It was running in addition to 2tph from Edinburgh to London in 2019. The London trains have more capacity and are better used. They serve "the north" pretty well too. I'm unsure what the third Newcastle to London service has to do with how frequent the TPE services between Edinburgh and Newcastle are.Personally I think is needed more so than an extra Newcastle to Kings Cross, also levelling up the north.

Not withdrawn, but reorganised. They still need to have the units transferred between the Liverpool - Newcastle services and their facilities in Scotland for trains and crew.I thought I read that TPE would be withdrawing from Newcastle - Edinburgh. How many fast trains per hour do you need on this section, two, three at the most?
