On RTT yes, but it's Reverted to 1V35 on the system.The only 08.10 I can see from Crewe to Cardiff is an ecs movement, 5V35? Which matches in digits the 5Z35 Chester to Crewe and 5F35 Cardiff to Canton.
The 08.10 is pathed through to Carmarthen, so I guess it's an ecs part using the path of a passenger service as far as Cardiff; an ecs move for 175s would make sense - and it doesn't mean they'll be coming back into service.
May well not happen though could Just dissappear like last week or go back to a class 5 ecs
