I don't recall the closure event on Taunton-Yeovil, only heard about it afterwards. It was one of those lines where each of the half-dozen services in a day might have a different class of loco. 45xx, 4575 (different shape, bigger tanks), 41xx, 61xx (Taunton got several of these in the 1960s displaced from Paddington, wonderful locos), 82xxx (the opposite), and 57xx Panniers. Yeovil would send out some of the same, and also 412xx tanks and N class 2-6-0s - 31840 for some reason seemed to be used more than any other. Like most of the sheds west of Salisbury, a lot of what was sent out each day was actually Exmouth Junction allocated locos. Yeovil shed, alongside Town station, quite commonly had three or four Bulleid Pacifics on hand, though they never came to this line. Prove me wrong somebody. Never saw a D63xx diesel on it but have seen pictures, nor a dmu, but apparently it had previously had a GWR diesel railcar turn, one of the original ones without buffers, which broke down at somewhere like Martock with a jammed transmission and was a nightmare for the Taunton breakdown crew to recover.
Only use of the line I made was a summer excursion (maybe two) to Weymouth, reversing at Pen Mill. The stock was equally diverse, old GWR B-sets, BR standard non-corridors, and green Southern coaches, these being the only corridor ones. That Sunday excursion was in a B-set.
