37197 & 37158 arrive at Llandrindod Wells on 26 May 1996 with the diverted 06:49 Margam to Llanwern steel train. This was one of a number of steel trains diverted over the Central Wales Line over the Bank Holiday weekend due to engineering works in South Wales. An amazing diversion considering the short distance over basically level track between Margam and Llanwern had been changed into a tremendous detour via a reversal at Craven Arms, over a single track line with some fearsome gradients!
