Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

I can't, its an internal discussion. But the assertion is that the track geometry for the the highest speed TGV's is 30% slope, the track geometry for "regular rail everywhere in the world" is 20% slope, therefore high-speed TGV's are restricted to TGV only track almost exclusively.

Is the distinction between the highest speed corridors and the lower speed corridors track geometry or the actual layout of the track ... curve radius, etc?

My belief is that he has received a garbled interpretation of a poorly understood fact from the middle of one of those pointless arguments between Express Rail and HSR.

However, I had only inferred the opposite from what I had gathered regarding TGV's, and did not know it directly.


I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
