The BBC mentions that Network Rail are finally looking at putting in a flyover across the East Coast Main Line at Hitchin so trains to Cambridge will no longer have to cross three tracks, including the express lines. Cool beans. The Network Rail site has pictures, track plans, lots more detail, and a video.
Aside from the practical benefits of fewer delays, alternative routes, and so on, it looks quite impressive too. It is due in 2014 if all goes to plan, including planning applications in 2009.
