Abstract

Public transportation plays a huge role in the lives of everyday Londoners. It allows for fast and efficient travel across the city while helping to decrease pollution and traffic problems, though it hasn't always been this way. In this article we will discuss the history of London's transportation systems, what made them successful, comparisons of methods of transportation, and predict where transportation is going in the future. Andrew does not have much experience with humanities and arts courses at WPI. He has taken one writing course, WR 2010, and has taken two other writing classes at another institution that he was able to transfer the credits from. Emily has taken 2 history courses and 1 philosophy course at WPI: HI1332, HI2332, and PY1731. Our major take away from this project is seeing the transportation system as a living thing. It is constantly growing and evolving much like a living thing. It also brought us to see its importance regarding the growing of London into a world city. Without effective means of transportation, the city would not be where it is today.

Introduction


The goal of this project is to understand the underlying causes of why the transport systems of London have become iconic to the city and give input on what the possible future of transport technology could be. Also, the project aims to make comparisons between these systems and other systems from around the world, in order to uncover the reasons for why and how they have evolved differently from each other or how they have become similar. We believe it is important for everyone to understand the history of transport technologies and systems in order to look ahead to the future and be able to improve upon the strong foundation that has been in place in these systems for years. Also, without public transit systems like the Tube or the double decker bus, the city of London would most likely not be able to function in the way that it does today.

Our methods of research for this project were somewhat different from past experience in HUA courses at WPI because we were able to utilize museums, specifically the London Transport Museum, to find information for our background section. Neither of us have had the opportunity use a museum so much for information in this kind of project. We also used methods of research such as books found at the library and journal articles found on the internet, which we are both very familiar with from past research experiences.

Section 1: Background


The Tube


History

The world's first public railway was a horse drawn line near London in 1803. Steam locomotives would come to take the place of the horse in 1825, when the steam engine was applied to passenger trains. George Stephenson built the first inter-city passenger line in London, the Liverpool & Manchester Railway, in 1830[1]. The first suburban railways opened in 1837 and took passengers from London to Paris and vice versa.

In 1854, The Metropolitan Railway Company was given the task of building an underground line to relieve the city traffic congestion. The underground construction also meant that no property needed to be destroyed at ground level, in central London. This line would bring passengers to Paddington, Euston, and King's Cross stations[2]. This line would be known as the Metropolitan Railway.

Outside of Central London, in the 1860s the main southern lines were given permission to extend across the river to Victoria, Blackfriars and Cannon Street and shortly after this the Northern and Eastern lines were given permission as well to expand. Due to this expansion, by 1900 London had more terminals than any other city in the World. Unfortunately this meant that at least 100,000 British people had their homes destroyed by the creation of new lines and stations[3]. In addition, railway companies were not legally responsible for finding places for them to live, leaving thousands of people homeless.

In the early 1900's, thousands of people traveled to London's city center for work from the suburbs. Horse drawn carriages could not take them the distance needed to get to their jobs. Trains became the preferred mode of transportation. This allowed the middle class to move out of the city center to more affordable suburbs and still work in the city. In 1912, it was estimated that 25% of all riders rode the cheap, early, workman's train. This 25% was dominated by men. Women often rode the suburban rails for leisure travel.

During the beginning of the Second World War, preparations were made to protect the city's transportation systems because many feared that the city would be destroyed by Nazi air raids. Staff for the various transportation systems were trained in fire fighting and first aid in case of emergency, and some of the Underground's stations were converted to air raid shelters. The government also utilized the underground stations as administrative offices and for military purposes. Evacuation procedures were also created in case of emergency, so people could find safety in case of an attack situation. Similar to many other jobs during World War II, women began to replace men working on the Tube as they went off to war[4].

Technology that made the Tube possible

With the ability to harness water pressure, the first lift was installed into the underground in 1890. This was the first lift of its kind because while Elisha Otis (who did work in Worcester MA) was building lifts to bring people up floors, this lift was designed to bring people down levels. This lift brought people down 50 feet. Those who rode it said it gave them the sensation that the earth is rising around you. Without this technology, the tube would not be where it is today. People are more inclined to use the tube because it has a safe and easy way to get to the platform as opposed to taking 5 flights of stairs with their stuff (baby carriages, groceries, etc). It also allows the handicapped to easily access the platform[5].

Electricity was another major technology that allowed the tube to thrive. Prior to 1890, the trains were not electric. This means that they were using steam engines. When you are 50 feet below the ground in a concrete tube full of steam-exhaust, it gets quite warm. People often did not take the trains because it felt like torture, an article in The Times wrote in 1884 "a journey from Kings Cross to Baker street is a form of mild torture which no person would undergo if he could conveniently help it". They would rather walk than pay to go into a boiling hot tunnel[6]. With the introduction of electricity, tunnels became cooler and quieter. This attracted more people and made the ride more enjoyable.

Similar to the invention of the lift, the escalator became a necessary part of the Tube, after its first use in 1911, as it expanded deeper underground. Traveling to the track from ground level could become a very strenuous task in certain stations that go very deep underground, such as in the Angel underground station where one escalator rises 27.5 meters vertically[7]. Climbing this distance on a staircase would be very difficult for some people and by implementing the system of escalators the Tube has become accessible to many more people.

A much more recent innovation that helps the London Underground system run smoothly is the Oyster Card. Launched in 2003, the Oyster Card was simply a card with microchip technology that allowed the passenger to more easily enter the tube, by simply tapping their card on the yellow circle on the gate to enter the station. This is a fast and effective way to get passengers in and out of stations, making busy morning commutes much easier. However, the original design of the Oyster Card was somewhat flawed because it was easy for hackers to clone Oyster Cards. The cards were changed eventually and now used radio-frequency identification (RFID) technology. RFID technology uses an electromagnetic field to operate. The Oyster Card has contributed to the popularity of the Tube as well, because it is convenient for many commuters to easily check travel records and the balance of their card online[8].

Successes and why

The tube is popular for numerous reasons. It is a fast and efficient way to get around the city. It can reach speeds of up to 20.5 mph in some areas and 60 mph in the metropolitan line without having to worry about the city traffic above ground. It has 250 miles of track so it can take you almost anywhere in the city you can think of. The flat fare is also another reason for its success. This started in 1907 with a rate of 2 pence. This was fairly cheap for the time and allowed people to get across the city. People saw it as a major convenience.

The tube gained so much success because it played an important role in the development of suburbs outside of London. Suburbs at Neasden, Wembley, and Pinner were built close to railway stations which helped improve inner city overcrowding, by allowing Londoners to expand in all directions away form the city. Wembley's population grew by 552% with the expansion of the tube and Harrow gained over 100,000 new residents in the time between the World Wars[9]. Specifically suburbs to the North-West of the city, such as Edgeware and Kenton, grew substantially.

Today, the Tube is still extremely popular, and its is showing a continuous pattern of exponential increase. In 2007 over 1 billion journeys on the tube were recorded. Also, in 2011 there were just under 1.2 billion users of the tube making it the third most used metro system in Europe, behind Moscow and Paris's systems[10].

The Double Decker Bus


History

The London bus dates back to 1829 with the introduction of the omnibus. Due to licensing regulations, monopolies of public transportation in the city center were tightly controlled. To get around this, George Shillibeer ran his omnibus on heavily traveled routes outside of the city. This bus held 22 passengers and had only one route: from Paddington to Islington. This bus would often get crowded so uncovered seats were added to the roof, creating the first double decker bus. As they gained popularity, features were added to them such as a roof on the second deck. It was advertised saying "(the) omnibus is fashionable, French, and suitably respectable for Ladies and Children." Eventually the government stepped in, in 1832, to end the monopoly of public transport and competition among bus services began to rise[11].

As public transportation became more popular, the bus lines expanded to accommodate more places and riders. During the first world war, public transportation became less reliable and led small independent transport companies to step in to solve this and make a profit. So many companies stepped in that the roads became reckless and dangerous. The government had to intervene to combat this issue and created a single authority responsible for overseeing London's public transport. This authority was later named the London Transport.

London Transport became a national authority in 1948 and was overseen by the central government. In 1970, oversight of London Transport was given to the Greater London Council. With the deregulation of bus services outside of London in 1986, oversight was once again shifted to the central government. The government then went as far as abolishing the Greater London Council. The government then created London Buses Limited. London Buses Limited had to compete against privately owned operators for lines and passengers. Currently buses are run by Transport for London which is overseen by the Mayor of London, who creates and implements transport strategies that will accommodate growth[12].

Technology that made the Double Decker Bus possible

Bus technology advanced the same as car technology. The same factors that allowed cars to gain in popularity and safety also apply to buses. The cab over design of the double decker bus gave it successes in the city. It allowed the bus to make tighter turns which was important in the narrow streets of London. The tires also played a major role in the success of the buses. This can be seen in the 20th century when they switched the solid rubber tires to ones filled with air. This increased the buses traction on the road, making them safer. While they have come far from where they started, bus technologies are still changing. Currently in the city there are around 2000 hybrid buses and 8 hydrogen buses in the fleet[13]. They were introduced as a green initiative to reduce on carbon emissions in the city. Within the past year, the city announced that the first fully electric double decker bus will begin routes along the city. This will help tremendously with pollution as the current buses run using natural gas. This technology will help to cut on fuel costs and environment emissions thus helping the city be more cost efficient and be more sustainable.

Succeses and why

In 1920 the bus was the most popular method of transportation in London. By the time 1930 came around, the people of London were making close to 2 Billion bus trips per year, which was more than double the amount that was being made in 1921. The large increase in popularity was caused by many changing aspects of the buses and their routes. Covered second levels of the buses were created and new pneumatics made the bus ride much more comfortable for the passengers. Bus routes also expanded to be just from central London to the new suburban areas and into the country. These advances to the bus and lines gave passengers a feeling that they were being taken care of and also gave them a pleasant experience[14]. Traffic times were greatly reduced because less people were in cars due to the fact that they were riding buses. Also, for some people it was found to be more cost efficient to ride the bus to the same place one would normally drive. Today many people take the bus because it is cheaper than the tube and has more stops in different areas of the city. The bus runs consistently all night where certain areas on the tube close down or have limited service, this contributes to its popularity[15].

Section 2: Deliverable


How have both the Tube and Double-Decker buses become so iconic?


The Official Tube Map

One way the tube has become so iconic is through its very unique map. The map itself is very different from that of the New York subway or the Metro in Paris. The lines of the tube are placed on a white background instead of being placed on a map of what the city looks like above ground. This map is also very heavily copyrighted by the London Underground Limited branding regulations and any other version of the map are never used for this reason. Even when asked how they would draw London, many Londoners simply said they would draw the tube map. Londoners also have created many associations to Tube stops shown on the maps to locations in London. The Tube itself has starred in numerous movies and video games such as Skyfall An American Werewolf in London, and Call of Duty: Modern Warfare 3. This further reinforced the Tube as a symbol of London. Also in Harry Potter, Albus Dumbledore has a scar on his left knee that is an exact copy of the London Underground map. Associating the City of London with the Tube in movies, creates a strong relationship between the two and contributes to the idea of the Tube as a symbol of London[16].
The Tube has also contributed to some of the greatest artists in recent history. As you enter a station you are instantly flooded with poster and billboard space filled with bright and colorful signs, hoping to draw your eye. While today it consists of mostly advertisements and signs, there used to hang beautiful art. The art you are most familiar with in Tube stations today is busking. There are many famous celebrities that used to busk such as Ed Sheeran, Passenger, Robin Williams, Pierce Brosnan, Sheryl Crow, Rod Stewart, Steve Martin, and BB King. The Tube has become an important part of art and music culture in London[17].

The Routemaster Bus (double decker bus) has become so iconic because of numerous media portrayals and tourism campaigns. The bright red buses were originally painted that color back in the early stages of transportation to stand out from its competitors; now practically every bus in the city is red. These red buses can be seen in almost every movie that takes place in London such as On the Buses, Live and Let Die, Diamonds are Forever, and Harry Potter and the Prisoner of Azkaban. They were also seen in TV shows such as Some Mother's Do 'Ave 'Em. These buses further reinforced themselves as a symbol of the U.K. when they came to America for a 'Come to Britain' campaign organized by the British Travel and Holiday association. They drove from New York to San Francisco then back through the Eastern Provinces of Canada, traveling more than 12,000 miles. Some say this was a way to show North America that Britain was not as boring as it was portrayed in stereotypes. In San Francisco there was an exhibit in the San Francisco Museum of Modern Art called 'British Art Today.' It included pieces such as a bobby, town crier, mini-skirted beefeater and a Routemaster shipped in just for the occasion. This bus was seen driving between the city's famous cable cars on the hills[18].

Transportation in the Future

Between 1975-1985, peak speeds of the bus and Tube were 11% slower than in 1968. The decaying bus and Tube services promoted greater use of cars and worsened the traffic congestion. Many calls were made to the government to invest in maintaining these services but they were ignored as a way to keep taxes low for citizens. Present day Londoners will hopefully never have to experience this again. The gridlock, that was so common during the 20th century became a major problem and the government decided it needed to be dealt with.

To combat this, the future is looking towards autonomy and car sharing, and making our vehicles healthier to be around. Currently, diesel fuels themselves aren't a major health problem to humans, but their brake dust, tire rubber particulates, and road particulates are. However, diesel emissions are dangerous to the planet because they produce nitrous oxide, which many scientists believe is contributing to global warming. Most people feel that if we had electric cars we wouldn't have this problem. They have no emissions and are advancing towards becoming more efficient than petrol engines. The major problem with this is the electricity still has to be created to power these cars. Renewable energy can be used to create electricity but in the winter and at night not enough energy would be produced to fill the demand. We would need to resort to nuclear power, which is dangerous, or burning of fossil fuels, which causes global warming[19].

To solve this problem, scientists, engineers, and urban planners believe that cars will become autonomous and by having self driving cars, people will ride share or use ride sharing services. It would be similar to using the popular service Uber but there wouldn't be a driver. This idea can be further applied to public transportation. By creating electric autonomous buses, there would be virtually no environmental impact and eliminate bus bunching. Bus bunching is very common for the city of London's bus system. Bus bunching occurs when a few buses traveling the same route arrive to a stop very close together. This causes people to have to wait a long time for the next bus if they miss those. This can be eliminated because with autonomous GPS, it can tell where the other buses are and can keep them from arriving too close together. This would allow the buses to arrive on a set schedule[20].

The current problem with autonomous drivers is pedestrians and unexpected hazards. A self driving car or bus may not know how to respond to a situation a normal human could respond to. This includes traffic jams, emergency vehicles blocking lanes, pedestrians jaywalking, and emergency braking. While eventually the coding would get better to accommodate these, people will likely die or be injured before it is fixed. It is very possible to run these autonomous buses if there were more one-way streets and better road markings but until these problems are fixed, it is unlikely that autonomous buses will be a part of the near future[21].

Autonomous trains require separate analysis. They seem to be more and more possible each day. They do not have to worry about the problems that drivers would. They have to simply go forward and brake at different stops. While occasionally things or people fall on the track, train conductors often do not have time to bring the train to a safe stop because the station is a very short distance away. It is very likely we will start seeing autonomous trains in the near future. Trains are a very convenient and a cheap way to move a lot of people. By making them autonomous, there would be less delays and could potentially make the tickets cheaper for passengers. I highly doubt the reduce price though, because governments always need as much money as they can possibly get[22].

As with anything that is autonomous there is a possibility of a cyber attack. That is why governments have been very reluctant to switch from human-controlled transportation. Who knows how many people would be injured or killed if an autonomous bus or train were to get hacked. The scary part is there is no real way to protect against this. Often when things are hacked people look to see how the program was exploited then patch the exploit to avoid being hacked in the same way again. This would not be safe for transportation because peoples lives are at risk[23].

A major question from many is, what about the train conductors and bus drivers that this will put out of work? This question can be simply answered. As anything become more industrialized or autonomous, current jobs may be lost but it will open new jobs to replace them. If we make trains autonomous we lose train conductors. But we need people to perform system checks on the autonomous system to make sure it is running alright. If we make autonomous buses we lose bus drivers. But we need people to perform maintenance on these buses. It may be smart to keep a bus driver on board incase of an emergency or situation known to cause the autonomy problems. This way the driver will be there to handle the situationk[24].

To conclude once a way to get autonomous transportation to be able to properly react to real-life situations and prevent them from getting hacked, we will see the implementation of both. It may seem that people will be out of jobs thanks to autonomy but soon after new jobs will be created to take their place.

Comparison of the Tube and Double Decker Buses to Other Transportation Systems

The Tube vs. NYC Subway

While they were created around the same time, the Tube and the New York City Subway have evolved to be two very different transportation systems.

First, as mentioned above in the background section, the Tube map has always been a unique part of the Tube. Its design is simple, and does not incorporate the city landscape above ground. This is unlike what the New York City subway map looks like, shown to the right, where streets and bridges are shown directly next to and on top of, the subways lines[25]. Another reason the maps differ is that the Tube's map is heavily regulated and only one version is shown in stations, while the New York subway has many different versions of the map. The map shown to the right is only one of the many versions of the NYC subway map. The Tube map is often found easier to read because of its simplicity, in comparison to the New York Subway map.

Another difference between the Tube and the New York subway is the use of the contactless card. The Tube, as mentioned in the background section, uses an Oyster card which is a contactless and easily used pass to enter and exit stations. The New York Subway has something similar but much less convenient, the MetroCard or MTA card as some call it[26]. The MetroCard is not a contactless card and must be slid by the user who then passes through the gate. This takes away some of the ease of using a contactless card, like the Oyster Card, and could be the cause of long lines and congestion when trying to get into the station. This is only a minor difference but can cause problems in the long run, especially during peak hours of the subway.

Cost of taking these two systems also differs. The Tube's system of pricing is a little bit more complicated because the all of the systems of transport in London cover nine distinct zones, each of which has a different price. However, for simplicity fares in Zone one can be compared fares of the New York Subway. For a single ride on the New York subway the price is only 3 US dollars[27], but a single ride in Zone 1 on the Tube is almost 6.5 US dollars. The Tube is actually much more expensive for someone without an Oyster Card and making a single journey. If a passenger has an Oyster card they will be paying 3.25 US dollars per ride and a passenger with a MetroCard for the NYC Subway will be paying 2.75 US dollars[28]. These prices are much closer together but overall the Tube is still more expensive. Both systems reduce the price for having a card, which encourages regular usage.

Historically, both the Tube and the New York subway have seen increases in their usage with both cities currently experiencing population growth. However there are more journeys made on the New York subway, despite London having a slightly higher population. The New York Subway has over 5 million journeys made per weekday[29] which is much more compared to London's maximum number of journeys in one day, which was 4.8 million.

The Tube vs. The Shanghai Metro

The Shanghai Metro is one of the busiest Metro systems in the World. It is the third oldest metro system in China and holds the record for being the largest transit system by route length and is the second largest concerning its number of stations. Comparing sizes, the London Underground is substantially smaller, it has only 270 stations while the Shanghai Metro has 364 stations[30]. This is because the city of Shanghai has almost 3 times the amount of people living in the city that London has. Both railways are still expanding and there is plans to begin connecting the Shanghai metro to other subway systems in China.

A difference between these two systems is the way they passengers are charged. On the Shanghai metro passengers are charged based on mileage which is very different from the tube where passengers are charged based on what zone they are traveling to and from. The highest fare on the Shanghai metro that can be paid is 14 Yuan[31], which is equivalent to about 2 US dollars. Once again, similar to the New York Subway, this is less expensive than a tube ride in Zone 1.

Also similar to the Tube, the Shanghai Metro has a Shanghai Public Transport Card which can be used on all of the public transport systems in Shanghai. This card also uses RFID technology[32] like the Oyster card, but was launched 4 years before the Oyster Card.

Routemaster vs. San Francisco Cable Car

Similar to the Double Decker bus, the Cable Car is iconic to San Francisco. Its routes are much shorter and it has less frequent stops, which makes sense because San Francisco has a smaller population than London and has a smaller area in general.

The bus in London is much less expensive than the cable car in San Francisco. The cable car is 7 US dollars for a single ride while the bus is only a little under 2 US dollars. The high cost may be due to the fact that the cable car has experienced a decline in usage over time[33]. It is more of a tourist attraction rather than something people use everyday for commuting purposes because it does not go to the same spots in the city it used to. The bus is a much more popular method of transport for both tourists and commuters in London.

Conclusion


To conclude both the Tube and the Double Decker Bus have had a long history and can only continue to improve. Both have had a large amount of success and this success has led them to both become iconic and synonymous with London. They would not be where they are today if it wasn't for technological advances. Modernization and innovation allowed for the Tube to be more efficient than the NYC subway. If we were to further investigate this topic, we would go more into the operational statistics of running both. Such as operating cost, efficiency, and other factors to determine the price of a ride.
