37197 & 37158 pass through the diminutive Penybont station on 26 May 1996 with the diverted 06:49 Margam to Llanwern steel coils. 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!
