I think they hoped to get it out of the door to try things on and then replace with gen-2 supersonics which were no doubt to arrive. As you know they never materialized due to lack of reasonable economic demand. I think the sadder story are Soviet high-speed trains. There were one or two, they did some speed records, worked on some experimental routes and never got wide adoption. Only in the last 15 years there's finally some viable high-speed options. Including one of Soviet designs incidentally.

Seems like there's a commonality with Britain there. We had a world-leading high-speed train design (the APT), rushed into a press demonstration 6 months before it was ready; the project was cancelled but the technology found its way to Italy and then, more recently, back into trains that are now used on the route for which the design was originally intended.

    No, totally different train afiak. I don't think the Fyra trains will tilt (no need as they run on new lines designed for high speed operation).

    It went to Fiat Ferroviaria (now part of Alstom), not AnsaldoBreda (now part of Hitachi Rail) who built the Fyra.

    They have a common heritage. The APT design was developed into the FS ETR 400 which was a collaboration between Fiat Ferroviaria (who have gone on to produce the Pendolino, the train I was talking about, and are now part of Alstom) and Ansaldo (who, as AnsaldoBreda, produced Fyra; now part of Hitachi).

      Note the ETR 450 uses hydraulic actuators, as do the later Pendolino models, whereas the APT used electromagnetic actuators. (I'm unaware of any ETR 400 having ever existed; the prototype ETR 401 did, but that used passive tilt rather than the active tilt developed by BREL.) SIG, then owned by Fiat Ferroviaria, built the electromagnetic actuators used by the Swiss ICN and the British Class 390 "Pendolino".
