1976 was famous for the amazing Summer but March was a bit grim as seen on the 12th at Cardiff. L711 is arriving (presumably 52091 at the front), in the set was 59823 and completed the set for me! Remember when they kept dmu's together? The loco, by deduction, is probably 47504. It doesn't really matter at this distance in time. It's Cardiff and it's 42 years ago! Arnie Furniss.
