Cardiff Central station

Cardiff Central Station was a large railway where children being evacuated from London to the Wales countryside briefly stopped at in 1941. Tom Flanagan was left behind, but the train returned to get him.

In 2007, Jack Harkness, Gwen Cooper and Owen Harper chased Sean Harris through the station. Though they failed to catch him, Gwen caught his alien Quantum transducer and it activated, allowing her to see Tom in 1941. (TW: Ghost Machine)
