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

Many of your distances are too long, since roads take more curves than high-speed railroads. Your speeds are too high as well, since the top service speed is rarely the same as the top design speed - e.g. Beijing-Shanghai trains are limited to 300 km/h, London-York trains are limited to 201, Paris-Strasbourg trains are limited to 320, Seoul-Busan trains are limited to 305.

Some better travel distances - the French ones from Wikipedia, the British ones from actually drawing the lines in Google Earth and adding it up:

London-Birmingham: 181 km
London-Manchester: 295 km
London-Glasgow: 642 km
London-York: 303 km
Paris-Lyon: 425 km
Paris-Marseille: 720 km

Using the fastest speed attained every 1-2 hours, rather than the fastest daily train, we get average speeds of about 140 km/h on the WCML, 160 between London and York, 218 between Paris and Lyon, and 230 between Paris and Marseille.

I dealt with British distances in my own comment downthread; on the French, Wikipedia or this site can be used:

  • Paris [Gare de Lyon]-Lyon [Part Dieu]:the precise distance is 427.258 km (kilometerage changes: 29.426/0.000 at the start of the high-speed line outside Paris, 389.314/13.528 at the first station past the Lyon end; Lyon-Part Dieu: 5.010).
  • Paris [Gare de Lyon]-Marseille [Saint Charles]: I know the diary has Lyon-Marseille, but I too think this is more interesting (and non-stop trains bypass Lyon). The precise distance is 747.904 km (Marseille end kilometerage change: 711.001/854.580, Marseille-Saint Charles track endpoint: 862.057; I guess Alon forgot to add the Paris end conventional section), though for travel distance, you have to subtract 400 m for train length due to termini at both ends.

The best Paris-Marseille time is 183 minutes, giving a travel speed of 245.1 km/h.

Seoul-Busan is designed for 350. If their TGV knockoff can't do 350 yet it's their problem. Likewise for the Chinese if they don't want to raise speeds for whatever reason. Come to think of it, I should put the 225 back into the East Coast Main Line. Tough break if their signaling system isn't up to par.
