From the May/September 1982 - Aberystwyth trains pictures.

25298 (front) and 25322 are coupled onto the 08.45 Birmingham - Aberystwyth train at Shrewsbury.

The last Sunday Birmingham - Aberystwyth service produced a new class 25 for me in the form of '298 so I ended up with a day in Aberystwyth despite having an All Line Rover ticket.  (Let's just say that thankfully one of my friends exerted some pressure on my decision).
