London Underground Sub Surface Network

London Underground Sub Surface Network is a game on Roblox, created by ostarlo96. It is based on the London Underground sub-surface lines, which are the Metropolitan, District, Circle, and Hammersmith & City lines. Most trains in the game are free, except for the A60 Stock which costs 30 Robux to drive, and the D70 stock in its original livery which costs 20 Robux.

As of 2021, due to a hacking incident, players are required to join the group "The OGroup" to drive.

Trivia

 * The secret drink can be bought for 10 Robux. When drinked, it plays the censored version of the London Underground song by Amateur Transplants, which itself parodies the Jam song "Going Underground".
