Route 1: Kings Cross - Doncaster 

Post privatization, better, smoother video. Via the ECML. With a choice of classes 47, 55, 90, 91 and HST, all in one package! Bit of a crawl out of the Cross but there's plenty of high speed (up to 125mph) running on the electrified east coast main line despite the nasty climbs to Potters Bar and Stoke summit. Britains fastest railway.
