(Yesterday, 4:29 pm)Adrian wrote Gareth Dennis talks about why the East Coast Mainline is a mess North of Newcastle, in his latest episode of Railnatter: https://www.youtube.com/watch?v=R2SJRtjQidc - worth a watch!
I've just sat and watched this and found it very interesting and in turn there was nothing I didn't disagree with on the changes that are needed to the ECML between Newcastle and Edinburgh in terms of what he discussed.
One thing I did wonder in regards to capacity at Newcastle Central Station and options to increase it is where the sidings are adjacent to Platform 9 & Forth Street could you build an additional platform or 2 with an entrance from Forth Street as there is a gate from street level that leads up to the sidings?
