There are mass cancellations over the GWR Network today due to a shortage of traincrew. Significant routes badly affected are Portsmouth Harbour, Severn Beach and others round Bristol and Gloucester area later in the day. Services in the Exeter area are affected with cancellations on Exmouth and Barnstaple routes. One route which has suffered very badly is between Bristol TM and Cardiff especially in view of great numbers attempting to travel to Cardiff for T20 Cricket between England and South Africa. Late Engineering Work due to a track defect at Patchway has resulted in an hourly service between the two locations and, due to running over one reversible line in both directions, the Portsmouth Harbour service is scheduled to run independently from Bristol TM. This arrangement is due to additional time built in for the SLW. Many passengers turned up at Bristol TM for the cricket and there was a frantic search to try and resource Coaches and taxies but coaches are in place to cover the cancellations to enable people to return following the end of the match. Of the trains that did run there were just 2 carriage formations which were insufficient and approx 50 passengers left behind at Filton Abbeywood. The regular Sunday cancellations on the Paddington to Cheltenham route were, of course, taking place but there was a little relief today due to some of the South Wales to Paddington services (diverted via Gloucester due to track defect at Patchway) making special stops at Golden Valley stations.
