Please, please, Dovetail, if you make it I promise to buy: (in order of priority ) 1) London Underground, Piccadilly line, or maybe Northern 2) York to Manchester Airport, going through the Standedge tunnel 3) WCML London to Rugby, through the Kilsby tunnel 4) Birmingham New Street to Sheffield 5) Newcastle to Carlisle along the Tyne valley. Outside the UK Paris Metro would be cool (line 2 has high-level sections with good views in places) Thanks for listening.
I second the Tyne valley suggestion. Specifically I'd like to see it backdated to include the rail served industry on Tyneside and branches such as the one to Alston. Might even get the Tanfield and Bowes railways in though I get the impression that rope worked inclines are a bit beyond TS.
