That is exactly what it is - a trial. If you consider the LU
environment it is hugely varied and we have to start somewhere with
evaluating a relatively simple approach to providing level access into
the trains. Given that wheelchair space is at specific points in the
trains then this trial is designed with that in mind. Raising the
entire platform is not cheap and still causes issues at those points
where you exit the platform into adjoining corridors / stairs or ramps.
Solving one issue may well cause other more complex ones. The real
challenge centres on what to do with places like Bank Central Line
(curved) or compromise height locations like Hammersmith D&P where you
step up to District line trains and down into Picc Line ones.

That's easy - change the level of the track on either side of the
island, so that the Picc lines are lower and the District lines are
higher.

The only disadvantage is that when trains from either line are
diverted due to disruption, the H&S nailbiters will howl because the
level access is gone...
