East Coast Main Line

Comrade Misfit posted this train video yesterday (Because It's Friday). I wondered about the "ECML" in the title, and she replied:

Charles, yes, "East Coast Mainline" or "East Coast Main Line"...people disagree. It refers to the high-speed rail corridor between London and Edinburgh in the UK. It has no level crossings, one of the key criteria of high speed rail, and one of the main blocks to high speed rail in the US.

I'll be durned. That's something you never hear the talking heads mention.
