Trivia: Stations (with 3+ platforms) where you have to leave the station to change platforms.

Shotton is an interesting station. 4 platforms, but essentially 2 stations connected by a long path. The Wrexham platforms have separate street entrances, so I guess counts for this thread.

Even within the NYMR part, there is a need to exit to get between platforms 1/2 and 3.
From memory you also need to exit between the NR and NYMR platforms.

Barassie, though the third platform has been closed for many years.

Especially if you want to change from the low level platforms to the Wrexham bound platform at High Level. The path connects the low level platforms to the Bidston platform.

In years ago wasn't there an old barrow crossing which has long closed due to H&S?
