This is still an issue. I’m currently sitting at Paddington on 1C37, the 22:32 for Bristol, but we’ve been told it’s not going to leave until after 23:00 due to a lack of signallers, and nor is anything else.
A look at the open train times signalling map does indeed show every single train at a stand between Paddington and Reading. Seems quite a remarkable issue to have to deal with on such a major main line!
Can anyone with inside knowledge give an indication of how long it might take to resolve this staffing issue? I appreciate it takes months (years?) to train new signallers but even a “not before [date]” would be interesting to know.
