But all the platforms north of Harrow are still at compromise height,
with a step down from the 313s. Any provision for disabled passengers
could be taken into account by having a raised section in the northern
end of the platforms where the LO services stop and a lowered section
at the southern end, where only the Bakerloo line trains would have
doors; these short sections would have to be in the same spot at each
station and could line up with the areas of the trains with wheelchair
spaces etc.

Such raised sections have already started to appear on the Victoria
line, as part of the upgrade. It's quite unusual not having to step
down from the train.

Not only the Victoria line, they're appearing at other stations on the
LU network as well - the Northern line at London Bridge sticks in my
mind, but there are other places too.
