Network Rail has confirmed a level crossing where a train hit a car on Friday is one of those earmarked for closure.
A man in his 40s was taken to Addenbrooke's Hospital with serious head injuries following the crash between Cambridge and Ely.
His Land Rover Discovery was hit by a train on the private level crossing at Stretham where drivers have to call a signaller for permission to go over the tracks.
Network Rail is in the middle of a consultation to close more than 130 of its level crossings in the Anglia region.
Today a spokesman confirmed the Nairns No.117 crossing was among those it wanted to get rid of to improve safety on the rail network.
Drivers would instead be diverted to the A1123 Newmarket Road which passes over the railway line.
The Stretham crossing is a private crossing with no public right of way and a telephone point.
On Saturday, Network Rail confirmed no call was made to the signaller to get permission to cross before the crash.
