Duncan has created his own coalition of ten Members of Parliament calling for a new direct rail service between Oxford and Bristol.
They have written to the Secretary of State for Transport, Patrick McLoughlin MP, urging him to introduce the service and requesting a meeting with him to discuss it.
The proposed route would connect Bristol, Bath, Chippenham and Swindon to Oxford and Bedford, and is the key to unlocking the campaign to re-open Corsham station.
In their letter, the MPs call for the service to be included in the next Great Western franchise.
“An Oxford to Bristol rail service would better connect Chippenham and Swindon with the region’s important cities and would run along existing track that is currently being electrified, so would require relatively little new infrastructure.
“It is naïve to think either Wiltshire Council or the Department for Transport will ever rebuild Corsham station without a train service which would realistically stop there.
“Instead of making a lot of noise on my own, I have worked cross-party to enlist the support of other MPs – and even Government Ministers – to maximise our chance of success.
“We know people in Corsham have long wanted their station re-opened. Now I am looking to businesses and major employers to make clear their support for the economic benefits of connecting Corsham and Chippenham to cities and universities from Bristol to Oxford.”
