From the developer:
SimSig Drain is a simulation of the Waterloo & City Line of the London Underground, colloquially known as the “Drain”.The Waterloo & City Line has only two stations: Bank and Waterloo, with unidirectional tunnels between them. South-west of Waterloo there is a 5-track depot. There is no way for trains to enter or leave the line other than with the aid of a crane.
