I think thats a slightly more complicated issue than just the train system.

Hmm is that a coincidence?

I worked on the Market Weighton By-Pass in the early 90's and remember speaking to Humberside CC at the time about extending the by-pass around Shiptonthorpe, apparently this was the original plan but as these things take so long to get from planning to construction the costs increased so much that the Shiptonthorpe bit was dropped. I remember this making the tie-in of the by-pass more difficult as the alignment had originally been designed for the extended by-pass. Dualling the whole stretch from MW to York would cost hundreds of millions and unless bridges were installed at the junctions could increase the number of accidents. The government won't spend that sort of money for some years yet.

Cheeky!!
