Interesting façade

Thunder asked me to post this:

QUOTE (Thunder)I recently spotted this building with railway paraphernalia on the front of it, the left hand side shows a locomotive buffer beam and the other crossed telegraph pole and semaphore signal, this is repeated along the whole facade of the building, along with locomotive wheels, i wonder who knows where it is, there's no prises for the first correct answer, just wondered if any one recognised it?
