Nah, they'll just keep making the walls thicker and thicker.

Honestly, why must modern trains have four-inch thick hollow walls?
Thin, space-maximising walls with no poky-into-your-arm ledges are
attractive features of both A stock and Desiros.

Not to mention plenty of other trains on other metro systems such as
New York. It seems new train interiors in this country whether LU or
national rail seem to have a sort of pseudo nursery school look with
big chunky fittings everywhere. If Fischer Price were ever to design
train interiors they'd probably get a lot of business from the UK rail
industry.
