Not sure why they dont include scotland? There are significant lines there that are 25AC, as well as the Glasgow underground system which would be I guess 1500v.
Scotland is coloured green as far as the Antonine Wall or thereabouts, which is fairly accurate. Electrification is limited to parts of the central belt and East and West Coast Main Lines south of Glasgow and Edinburgh. They've accidentally left the Western and Northern Isles coloured green too.
Glasgow Subway is 600V DC, converted from cable hauled.
Thats interesting, I has thought it was the same as the London Underground system.
Yeah, its ECML and WCML. They WERE going to put in an AC link as far as Glasgow Airport (one of our contractors actually went so far as build a model of it), but they never actually built it.
