If you've been following some of the recent comments/posts on OTPgen, then you may have heard about 909001-8 derailing at Westerleigh over the weekend (30 Sept).

It had been working in a possession on the Westerleigh oil terminal branch, and derailed on some hand-points when returning to base (the old Avon refuse terminal)...

It was re-railed by a team from Margam and was taken away the following day by Allely's..
