Under a leaden sky, 37521 runs wrong line though Craven Arms station on 27 May 1996 with the diverted 6Z92 05:40 Llanwern to Margam steel coils. The loco has just round its tiny load, and would shortly be branching off for its circuitous detour via the Central Wales line. Bank Holiday engineering works had closed the South Wales mainline, but it hardly seemed worth the massive detour for just six steel coils!
