"what goes where and when."

Transport London Underground’s “secret” tube station:

"This is in fact a fully fitted out fake tube station built by London Underground on the 3rd floor of an office block in West Kensington and is used to teach new employees what goes where and when.

It is slightly surreal to go into a fairly generic office building, then on the third floor, find the entrance to a tube station – complete with fake newspaper stall and wire mesh grills.

Perhaps in hundreds of years when historians are trying piece together how we lived, they'll decide that there really was a tube station called West Ashfield.
