I'm not so sure. That document you linked went to every home in the form of a leaflet in central and north Bedfordshire. Bedford Midland has had a lot of bad luck with train timetables and OHLE works lately. The station itself is overly congested with trains and has become a bottleneck. I don't have the answers, but Bedford wants it wants and although funding has been granted to upgrade the station (Abellio report) it doesn't say anything about the lack of platforms available when the THL trains have at least 2 out of 3 of them for the most part of the day. Add EWR there and you have more congestion. If you read back though we did find that a 3 car unit will fit into p1A at Bedford. Which means if it stays that way Bedford Midland can accommodate EWR until the Cambridge section is built.
