Replying to my own reply ... lots of short forms. Some are probably because of 1 or 2
IETs▸ out of service because of last night and the lack of [enough] hot spares to deal with any shortfall; that may be exacerbated by depot staff not being as happy to work voluntary overtime bearing in mind industrial unrest.
09:23 Swansea to London Paddington due 12:20
Facilities on the 09:23 Swansea to London Paddington due 12:20.
This is due to the emergency services dealing with an incident.
Will be formed of 5 coaches instead of 10. There are no reservations on this service.
The stock shortage (again lack of [enough] hot spares) is seen wider too - here's a train down from 2 multiple units to one:
09:39 Bristol Temple Meads to Cardiff Central due 10:23
Facilities on the 09:39 Bristol Temple Meads to Cardiff Central due 10:23.
This is due to more trains than usual needing repairs at the same time.
Will be formed of 3 coaches instead of 4.
and another train short formed - perhaps the three coach train that would have gone to Weymouth has gone to Cardiff, one of the two 2 car units has gone to Weymouth and the now-unallocated 2 car unit is running an unreported service which would otherwise have been cancelled.
09:04 Westbury to Weymouth due 10:42
Facilities on the 09:04 Westbury to Weymouth due 10:42.
This is due to more trains than usual needing repairs at the same time.
Will be formed of 2 coaches instead of 3.
