From the May/September 1982 - Aberystwyth trains pictures.

25182 (front) and 25083 arrive at Aberystwyth with a special train from Euston.  In the background can be seen the stock off the regular Birmingham - Aberystwyth train.

The last Sunday Birmingham - Aberystwyth service produced a new class 25 for me so I ended up with a day in Aberystwyth despite having an All Line Rover ticket.  Just before heading off to Devils Bridge on the steam service another special train arrived bringing in a few more enthusiasts.
