a typical HSR train accelerates at 0.45 - 0.7 m/s². There's no way these trains accelerate faster than a Desiro; I have 0.68m/s² for the 102.

Thanks! About the accel/brakes, yeah I think that too, but according to a paper I found, the brake should be 1.27, and the acceleration should be the same as the 102 series, which is supposed to be 1.2. I'll try to balance it later with some videos to eyeball the accel/brakes.

oh yes, I have an acceleration of 0.53 for this train.

Oooh, very nice, especially with the couplers visible in the middle. I would say that the acceleration and braking rates are...a bit optimistic, though.

that is a very detailed mod, hats off to you
