GWR Journey Check states 1A40 will start from Plymouth tonight and will be held for
approx quarter of an hour for Cornish passengers who will travel up on a XC service to connect.
I am not aware which vehicle was affected but with another loco on the way it could have been the loco (57604) which looks destined to take the stock back to Plymouth/Laira
