All these photos were taken on a day trip to Reading on 29 July 1987.
In the bays at the east of the station are class 204 and 117 (?) units
33037 on a parcels train
One of the class 210 units
59003 on a train of Yeoman hoppers.
56059 on a stone train
50013 heads west on the 1145 Paddington - Penzance
50002 with the 1217 Paddington - Oxford.
I travelled home as far as Oxford on the 1612 Paddington - Oxford, hoping for a class 50 (I'd never ridden behind a class 50) but instead got 47500, seen at Oxford.
While waiting at Oxford for my train north 56111 headed south with an MGR train to Didcot.
