Today's 1C73 (0706 London Paddington to Penzance) failed on Rattery and had to set back to Totnes to get a run at the bank. It subsequently left Totnes 83 late and then ran non-stop from Plymouth to Penzance arriving 75 late. As a result, its next diagram, 1A89 (1303 Penzance to London Paddington) was cancelled between Penzance and Plymouth, where 1Z89 (1503 Plymouth to London Paddington) was substituted in 1A89's path.
At Newton Abbot, we then get the extremely confusing display
1641 London Paddington Cancelled
1641 London Paddington On time
And the even more confusing automated announcement......
"We regret to announce that the 1641 GWR▸ service to London Paddington has been cancelled. The next fastest service to Exeter St Davids, Taunton and Reading will be the 1641 GWR service to London Paddington"
Is it the responsibility of GWR Control at Swindon to make the appropriate changes to the display and automated announcements, or is it the responsibility of the local platform staff to make an appropriate announcement?
