A new station at (or nearish to) Devizes has go itself caught up in the need for a fourth platform face at Westbury which (surprise) cannot be justified based only on the extra station / traffic at Devizes. It strikes me as the same issue that the study of specifying from Newbury to Westbury came up with when the costs were loaded onto the two electric trains a day that would terminate at Westbury, and in contravention of the need to look at the whole picture including the net zero agenda.
More in another thread (I will copy elements here) and on Facebook
(here) Westbury is a bottleneck and needs a fourth platform to cope not only with more trains from the Devizes direction, but also for a better service from Swindon via Melksham, and a better service to Weymouth. More trains start this May from Bristol and on to Salisbury and it's creaking at the joints. To put the cost of what looks like a platinum solution onto poor little Devizes was never going to work economically. Better to extend the platform out to the track that's there and tell the freight operators to run to time.
