Old home town, Taunton, Platform 1, the west end down bay. It was always like this, in the 1960s this was always the Barnstaple line bay, where the bay further alongside was for Minehead. Being on the old station side it may well have had this oddball arrangement before the big 1930 station rebuild. The guard always checked both sides before departure.
New home town, Canary Wharf DLR station, all three tracks are like this, platforms numbered separately 1-6. It does facilitate some interchanges and access to adjacent premises. Similar elsewhere on the DLR. Tower Gateway is one track, platform both sides. There is an attempt with announcements to have one side for incoming passengers and the other for outgoing, quite widely ignored and takes no account of alighting passengers wanting to use the east end exit, only accessible from the other side.
Numbering the platform sides either the same of differently each side forms a subgroup of this sort of track arrangement.
