Would love to have the ECML from late 70s/80s with the Class 55 when it was running along side it's replacement the HST. Be nice as it joing the TVL. And ideally, getting the iconic Forth Bridge in would be perfect. I've always loved the bridge across the Tyne into Newcastle, and the stunning east coast scenery as yoiu go so close to the sea north of there.
Love the idea of having something join up with Tees valley. Could add an AI layer of passing traffic to the TVL route perhaps.
