Southbound train. All this on 600HP ! David j Hayes saysThis picture looks as though it was taken well into the evening and the loco appears to be displaying a BB headcode, which might imply a working to Hither Green. Several possibilities are given below and are based on WTT information for that period. Passing times for Kenny-O (KO) are shown in brackets: 8O23, the 18:25 SSuX Temple Mills to Hither Green (KO 7:32pm). 8O15, the 10:42 SSuX (Q) Jersey Marine to Hither Green (KO 8:05pm); believed booked to call at Acton Yard for traffic purposes*. 8O24 (BB), the 21:25 SSuX Willesden to Hither Green (KO 9:43pm)**. *8O15 could also run alternatively as 8O45 to Norwood Yard. Both 8O15 and 8O45 could also start from Cardiff (Tidal?) at 12:07 if so required. **May have been running earlier than booked.
