I notice in this contrast video I watched a few days ago in the 90s clips the trains seemed to bounce more compared to 2010 and 2024 clips. The d stock also bounced more louder than the 313 noticeably.
But even in memory, I think the 72ts use to bounce more in the late 90s than now. I remember as a toddler the bouncing would cause people to nice with it but maybe I just noticed that more at that age compared to now.
But I imagine, don’t factually know, that the 313’s felt smoother than the 378’s. But then I get 165’s and they feel smoother than some modern emu stock but I imagine it might have to do with how they coast? The coasting making the train feel like it’s sliding on the tracks more than if I heard the motors with make me think that the trains are dragging abit more on the track. This is just my opinion though, I may be wrong.
