966 (54494 & 53618) takes the Westbury line at Bathampton on 5 April 1990 as it works the 09:35 Bristol Temple Meads to Yeovil Pen Mill service. This unit had recently been transferred from Chester, where it ran as set CH252. On the Western Region the formation of 966 was fairly fluid, as although the rear vehicle here (53618) was constant, 54494 was replaced at various times with 54202, 54208 and 54191!
