    Wow, bad moment, but a bit funny. The traction system and the braking system was unsynchronised at this moment I suppose. The electric braking was off before the complete stoping of the train. The train should have been freewheeling before complete stop and finish softly the breaking. It's braking system problem.
    It's the same problem in a car, if you brake to much and press the cluch, the ABS work and brake hard.
    Moderns trains have anti clutch systems to avoid struggling and clutching.
    This system is maybe the guilty.
    The sound of this train is like GTO inverters, actually yes it is. GTO are slower and harder to control in comparison to IGBT, that also explain why electric braking stop before complete braking and maybe this situation.
