I don't often go on the DLR, infact yesterday was the second time
ever, and prompted a couple of questions.

1. are the rails made form recycled corkscrews?!? thats one hell
of a shimmy going on along some stretches, what's that all about?

It's a design flaw, and also the reason why there are sinusoidal
wear marks on the rails and a speed limit.

2. why are there drivers sometimes?

Unionisation?

They can occasionally be driven manually in emergencies, but the
reason why you sometimes see them at the front isn't because they are
driving.

As well as from each doorway, they can also operate the doors from
the front of the train. Sometimes it may just happen to be
convenient, and sometimes, eg at Canary Wharf, they need to be able
to use the mirrors to see both sides.

but why be on the train, operating the doors for a few stations, and
then not for the rest of the line?

I thought the train captain (are they still called that?) was always on
board, and always operated the doors, but only rarely drove. I think
they sometimes checked tickets at one time, though I'm not sure of they
still do.
