Replacement transport has been arranged but this is not expected to arrive into Trowbridge until 09:20. This will run from Trowbridge to Melksham and to Chippenham and then back again.
Classic illustration of the delay caused by road replacement transport in addition to the bus being slower.
As I read this, the 07:43 train (07:53 Melksham, 08:03 Chippenham,
08:19 Swindon) is cancelled because they don't have the right sort of staff to run it.
There's a bus expected at 09:20 from Trowbridge, which will be 09:35 at Melksham and 09:55 at the earliest at Chippenham. Very unlikely to catch the 09:56 to Swindon so the next train will be the 10:11 and get people to
Swindon at 10:34. Ironically, that's the bus connecting into the next train from Westbury ...
Thank you to
GWR▸ for honouring their promise to lay on a bus if this train is cancelled. Yesterday there were (look back at notes) between between 50 and 60 passengers using this train. But I wonder how many of them will still be there for the bus ...
Return bus - say - 10:00 from Chippenham in place of the 09:00 train, say 10:35 into Trowbridge rather than 09:19, connection to
Westbury at 11:00 rather than 09:26. Slightly more useful than the bus the other way, as after 09:26 the next train arrival from Swindon is not until 11:47.
Oh for an appropriate hourly train service. Cancellations would still be regretted, but it would render the need for a practical alternative (which these buses today are not!) unnecessary.
