The data is usable for a Scotland Yard map with stations from 1 to 199. There is an other version that ends at 200 but the station 108 is missing in this version.
The base version of the data was created by @frog32, but I, @AlexElvers, have corrected many station positions and connections.
The station number, x-position, y-position and the station type are separated by a space.

Both stations and the connection type are separated by a space. The first station is smaller than the second as there are no one-ways and the data is an undirected graph. Whenever there is a connection from A to B, you have to ensure that it is possible to move from B to A.
