For odd little termini, visit the north east.
Whitby is now a single track/platform affair, although it still retains some of its former glory in its station frontage buildings and facilities.
Battersby, now theres an odd one which used to have a through line, now requiring through trains between Teesside and Eskdale to reverse.
Bishop Auckland used to be an important junction station with six radiating routes and was set in a triangular shape. Now its a single platform with shelter at the end of a bumpy branch line. Even the mothballed through line to Weardale passess the wrong side to the current platform.
Those stations are all single platform affairs, have all at more significant origins and are all now quite adequate for the measley service they accomodate.
There are however single platform termini omn far busier routes, though these also have much shorter turnaround times. These are South Shields and South Hylton on the T&W Metro. The latter is also on the site of an old through route, the typical closed crossing standing as evidence to what was a railway and now is a cycle route to the Leamside line at Penshaw.
Saltburn is the only termini in the north east iirc with two platforms, though im not sure if both are used and sees a regular half hourly service. Interestingly it's situated on a spur from what was the old through route to Whitby via Redcar, which is a freight only branch today serving Boulby potash and Skinny.
