I'm a little surprised that they claim it uses less power than a
conventional lift. If you have to raise a given mass through a
given vertical distance, shouldn't the answer be the same?


More efficient and I suspect the actual lift body weighs less than a
wooden escalator.

He was comparing it to a conventional lift, not an escalator. I think it
needs a less powerful motor than a vertical lift as the rate at which the
weight is lifted vertically is less.

In any case, the old escalator was wood-panelled, which wouldn't have
affected the weight of the moving parts. They could have fitted a second
escalator in the same space, but that wouldn't help people in wheel chairs.
As it is, the able-bodied will be able to ascend using the other escalator,
but are expected to walk down the stairs when arriving at the station.

These inclined lifts are apparently much cheaper than conventional lifts,
and are a cost-effective way of providing step-free access in stations that
have multiple staircases but no convenient place for a vertical lift shaft.
