The West Somerset Railway have announced the use of an additional loco hauled diesel diagram on the following dates:
SATURDAY 29TH APRIL, SUNDAY 30TH APRIL, MONDAY 1ST MAY
09:35 Bishops Lydeard-Minehead
11:10 Minehead-Bishops Lydeard
14:55 Bishops Lydeard-Minehead
16:45 Minehead-Bishops Lydeard
The service on each day will be operated by one the DEPG Locomotives based at Williton
I'm guessing these will be operated by a 33, 35 and/or a 52.
