Opening and Closing the Passenger Doors looks way too stiff. There needs to be a little bit of a rocking motion on the doors when they open.
As far as I'm aware, the door animations are realistic in most trains. Exceptions are for example on the 72 Stock the doors start closing a bit too quick, and on the 38 Stock the doors are way too fast and for some reason the guard's signal is rung before the doors close instead of after they're completely closed. Apart from these two, they seem pretty realistic.
