Apologies. I was due to travel but abandoned plans because journey check starte there was no service between Worcester and Paddington. Didn't realise there was a partial service running.
Journeycheck is an on-the-day state of service indicator, not a journey planner.
In addition to the shuttle trains to and from Hanborough on Sunday, there was an 18.16 through service from Hereford to Paddington, which was routed from Worcester via Stroud, and 18.22 and 20.22 departures from Paddington also ran, reaching Worcester via Stroud, as is typical when the route via Oxford is not available.
There will be a limited through service for Worcester/Hereford via Stroud for the next three weeks during the Oxford resginalling blockade, in addition to the handful of trains that normally run that way.
