well yes, but only up to as point. It's necessary to step down from existing train services to the platform because... well because the train was built that way. For some reason that's a bit mystifying the size of the step is occasionally bigger than usual and they have an announcement to warn us. Doubtless the Victorians can be blamed, but why the solution is an announcement rather than some civil engineering is anyone's guess. I've been vaguely puzzled about this for years.
It all seems most peculiar to me, and they probably had to write a special exemption into the DDA to make it legal
.
But here is an opportunity to organise the new railway so that there is no step by, eg, building the train to fit the existing platforms and if there's a discrepancy at some station to make the platform fit the train (as they did on the Victoria line a few years ago). Having designed the train around the existing stations they can then design the new stations around the train.
On the same theme I wonder about the
mind the gag gap. It's inevitable on platforms built on a curve, but not all of them are, some are straight. So why not move the rails over a few inches, why insist people have to jump?
