As I mentioned, the added factor is the start of services on the 1st section of the east/west route, from Oxford to Bletchley. Track laying is completed and it is expected that the infrastructure at the Bletchley section will be handed over to Network Rail later this year, for services to commence, extending to Milton Keynes in 2025. Chiltern is the passenger service operator. As east/west will be an evolving route, as the next stage from Milton Keynes to Cambridge is constructed, they may be looking at using currently available stock in the interim, for the truncated first part of the route.
