London Underground’s 'Secret' Tube Station

Ianvists.co.uk has an excellent post about a London Underground station that is used for training. What's unique about it is that it's built on the third floor of an office block!

The station comes complete with a platform, Oyster card readers, signalling and display boards although the trains don't work. There is a also a model railway and a simulator that is used to train LU staff.

Ian has posted lots of photos although with a detailed account of his visit to 'West Ashfield Station'
