I tried to find something equivalent in Europe to compare, maybe Frankfurt to Berlin? Google Maps is showing that as 4h16 by ICE over 549 km, for an average speed of 128 km/h. Ah, I took the ICE from Frankfurt to Berlin last year on a last minute ticket. A bunch of things come to mind. In no particular order:
- Tokyo - Kyoto is pretty much the premier Shinkansen line. Is Frankfurt - Berlin considered the same?
- I was pretty underwhelmed with the overall comfort on the ICE trip (slightly less than Amtrak's Acela). The Shinkansen (well, at least Tokyo - Kansai Region) is really on a whole other level.
- A last minute ICE ticket Frankfurt - Berlin was fairly expensive (> $100 if memory serves), I didn't price advance tickets. Berlin - Amsterdam tho got dramatically cheaper the further out you booked your ticket.
- Spain's Barcelona - Madrid train has regularly raised its peak speed (now at 310 kph) and if my calculations from the Wikipedia page are correct RENFE completes the 621 km trip in 2.5 hours (about 250 kph average).
- Amsterdam Centraal is perhaps one of the most obnoxious stations I've had to navigate. Every Dutch resident I've talked with has complained about the punctuality followed by complaining about how unnecessarily unintuitive the fares are.
Germany still has a fair amount of diesel service and a ton of legacy infrastructure. Spain is basically converting all of their non-standard gauge rail to a more common gauge and rolling out a ton of high speed service. I've only done relatively short trips (Madrid - Toledo) versus a variety of longer distance trips in Germany.
