Following the research I (Owen Dunn) did late last year into the operation of the Fen Road level crossing I sent a letter to the Rail Minister, Jo Johnson, asking whether anything could be done to improve the situation. I've now had a reply from the DfT's policy lead on level crossings.
Bertie Bricusse from the Department for Transport writes:
I recognise that there may be scope for reducing the amount of time the barriers are closed, including the suggestions raised in your letter. I have asked Network Rail to consider these options and to contact you directly, so that you may be able to take these ideas forward.
I look forward to talking to Network Rail to see what we can do for the communities and businesses to the east of the railway line, and I'll also be discussing these problems with the County Council in the next couple of weeks. Needless to say, I'll post updates here when I have news.
