I took the Paris-Tours TGV, and my best guess is we hit 110-120mph. What's even more impressive is the almost silent, very smooth operation up unitl about 60 mph. Like a hydraulic horizontal elevator. You won't see a ripple in a water glass until 70 mph. Standard European rail widths are the same, in fact the same all over the world. Russians are very different, and narrow gauge railways are different. During the steam age you could travel by train from one European city to the next on the same train. en.wikipedia.org Details of flanges, angles, track flexibilty etc. become critcal at high speeds, and need to be controlled. Voltages are another concern. I was told actual cost of the TGV was about 3 X the ticket price. This from a guy whose job was to sell the system abroad.
