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.

Perhaps the design is intended to PREVENT people standing too close to
the doors when the train is packed.

Just because there is room in the loading gauge for steps at the doors
doesn’t preclude the body profile being shaped for loading gauge reasons.
The limit on body shape will be at car ends and centres where the throw on
curves is greatest. The doors, closer to the bogie centres have less throw
so can accommodate a large step, but the body profile can not easily be
contoured to make a wider floor in the door vestibules.

The 313s they're replacing on the moorgate branch are slab sided and don't seem
to have any issues but maybe the floor level is higher.
