Here are the biggest ones.

To use this method, builders dig a trench in the riverbed or ocean floor. They then sink pre-made steel or concrete tubes in the trench. After the tubes are covered with a thick layer of rock, workers connect the sections of tubes and pump out any remaining water.
When I posed this question to Michael Horodniceanu, he immediately made a clarification: The subway tunnels in New York are not necessarily "underwater," but rather, underneath the riverbed. Workers would dig by hand through the riverbed, placing cast-iron rings around them as they went.
191st Street is the deepest station in the New York City Subway system, at a depth of about 180 feet (55 m) below street level.
A few early subways used steam engines, but in most existing subways, the trains, tunnel lights and station equipment all run on electricity. The third rail lies outside or between the subway tracks, and a wheel, brush or sliding shoe carries the power from the rail to the train's electric motor.
The Park avenue tunnels were 24 feet in width by 18 feet in center height, the tracks being 12 feet center to center. The deep tunnels were 25 feet wide by 18 high.
The London Underground first opened in 1863 as the oldest section of underground railway in the world, running between Paddington (then known as Bishop's Road) and Farringdon Street on what is now part of the Circle, Hammersmith and City and Metropolitan lines.
The average speed on the Underground is 20.5 miles per hour, including station stops. On the Metropolitan line, trains can reach over 60 mph. The shortest distance between two adjacent stations on the network is only 260 metres and the longest is 6.3 kilometres.
The tube is deep because it had to go well under existing buildings to no interfere with their foundations. Most of London is clay, and if you destabilise it near buildings, they suffer.
Around 60 stations had the Metropolitan line's red diamond instead of the “roundel” between 1919 and the 1970s. The Underground Sans font, still used in a modified form for all the Tube's posters and design, was created by Edward Johnston in 1916.
Dave Welsh (Letters, 21 May) says the London underground has been publicly owned for 80 years; it was actually nationalised, along with the rest of the railways, by the Attlee government in 1948. The London Passenger Transport Board of 1933 had a complex structure.
The London Underground is a system of electric trains that are in London, UK. Even though it is called the Underground about half of it is above the ground. The "Tube" is a slang name for the London Underground, because the tunnels for some of the lines are round tubes running through the ground.
The largest and most complex metro station in the world is the Paris Métro-RER station Châtelet-Les Halles in France.

The Beijing Subway is the metro system with the longest route length and highest ridership. The New York City Subway has the most stations. The London Underground is the oldest metro system.
Rapid transit or mass rapid transit (MRT), also known as heavy rail, METRO, subway, tube, U-Bahn, or underground, which is a type of high-capacity public transport generally found in urban areas. Metro word has become popular from word of mouth. 203 views. What is the full form of VRE?
Less power usage, very high space occupancy. The Metro Rail System has demonstrated to be the most effective in the transportation. Metro rails are very High-capacity carriers and journey hours are very less than compared to road ways. It is Eco-friendly – no pollution of the air, much less noise is produced.
A Metro Train is named as "Metro" because it is most sutable for the Metro Cities or metropolitian area which have large population. Not all Metro Systems use Metro in their names, like in Toronto it is named as "Toronto Rapid Transit" and in Beijing it is named as "Beijing Subway" .
Metro trains do not always run underground. Most metro systems that run underground in the city centre also have stretches where they run above ground farther out. Building underground is expensive, so it is only done a last resort.
For some of us living in big cities, imagining our lives without the Metro would be difficult. The method of transport allows us to travel major distances much faster while simultaneously helping us skip the road traffic and greater exposure to pollution.
Your target audience is on the street, not in the sky! I generally leave about 80-100 units between metro stations, and get pretty good ridership (~60% car trips saved). What helps is that all my high density and businesses are clustered around stations, to maximize the number of trips that the metro is useful for.
2 Answers. If you'd like to delete an entire transit line, you can do this by clicking on the Transit overlay from the info panel in the top left corner, which allows you to click on transit lines to modify their name or color. There is also a "Delete line" button.
Mass Transit brings several new systems into play to help citizens traverse their towns in speed and style. Commuters can now get around on water, up high mountain peaks, and even through the sky thanks to the addition of ferries, monorails, cable cars, and blimps.
