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

Is there a move to standardise line speeds internationally ?

Right now you seem to be suggesting there's an incremental increase with certain lines that are being built. Yet that seems short sighted for the simple reason that the track build and trains become a matched set which, due to the lack of replication, becomes expensive. Better for customers to gravitate to a secure widely available technological solution. It's only supplier organisations that have a real vested interest in continuously upping the ante.

That's not to say we shouldn't develop faster transport systems, but I think that there is a general limit being approached between the ability overhead wire - pantograph interface to convey sufficient power at high speed and the ability to develop high speed electrical motors within weight limts versus the damage to the track. Single percent improvements on this are probably ceasing to justify the increased costs inherent in customised solutions.

TGV was a generational improvement in railways. I thin it'll probalby be another genenration before we get such a leap forward again.
