Does anyone know why the new Siemens 7** classes curve inwards towards the
bottom of the doors which makes its very awkward to stand next to the doors
when its packed? It can't be loading gauge issues because (until the LU S stock
where it was done to fit in the platforms when they dropped the floor height)
there's a socking great step protruding out probably 6 inches from the bottom
of the door.

This seems a strange design decision to me.
