The company has also said it wants passenger services to be battery-electric hybrid trains.
According to David Hughes, the East West Rail chief executive, “more frequent and higher-capacity trains alongside a new station at Cambridge East and a new entrance at Cambridge station, will help unlock housing, support new jobs and attract investment”.
But the EWR scheme has come under criticism from some living along the proposed route.
According to William Harrold, from the Stop the Arc pressure group, which opposes development between Oxford and Cambridge, local people are “very worried about the effect of the construction on the rural road network”.
“Where are the 24/7 HGV routes going to be?” he added.
Hughes said that he “encourages residents, businesses and stakeholders to take part in the consultation and share their views on our latest plans”.
The consultation is open until 9 June.
