C583 (51069, 59428 & 51097) passes Pirton on a very warm Sunday 15 June 1986 with the late running 16:33 Swindon to Worcester Shrub Hill service. Note the crudely applied C (for Cardiff), replacing the former B (for Bristol) in the set number. This set was disbanded the following year, with all three vehicles going for scrap, the two driving cars at Mayer Newman, Snailwell, and the centre car at Vic Berry's, Leicester.
