Sadly, true.

Hmm , I'm not sure how well dry grass in the summer would get on
with sparks off the 3rd and 4th rails!

Lucky nobody's told them about Richmond, Harrow & Wealdstone or
Harrow-on-the-Hill, then.

Those services are historical and we're set up long before the
current generation of bed wetters got into power. They'd never
be allowed to be set up today.

Unprotected 3rd rail would not be allowed today on an entirely new
railway, but that has nothing to do with mixing tube and mainline, both
of which use the same technology at Richmond, except that LU is 4-rail
rather than 3-rail.
