Did you know that each successive generation of German high-speed trains has had air-conditioning plant built for higher temperatures? The trains from the early 90s handle a temperature range from -20 to +32 degrees Celsius. Those from the mid-90s, -20 to +32, but if necessary they can exceed that. The ICE Type 3 handles temperatures up to 35 degrees, and the ones still to be delivered up to 40. And the next class? They’re planning for 45 degrees. Apparently the International Railway Union standard is going to be revised upwards.

    Yes, climate change, obviously, but later German (or, actually, Siemens) kit is clearly intended to take on Alstom in the export market, and that includes hotter places than Bremen (Spain, for a start).

    IIRC the first gen ICEs have some loading gauge restriction that seriously limited their interoperability. Not entirely surprising that other elements were specced parochially. The later ones are rather more flexible, being aimed at the export market too and there’s a fighting chance that they’ll operate London-Cologne before too long, if (in a rare example of Elf’n’Safety really having Gorn Mad) the powers that be on the Channel Tunnel decide that it’s perfectly safe to operate the same type of trains that, say, operate on the long Alpine tunnels without too much bother. It’s not like the Chunnel has the world’s greatest safety record even with the over-stringent regulations in place.
