I don't see tube stock clouting any of the bridges. between Ealing
Bdy and West Ealing. WRT to speeds, 92 stock accelerates quicker
than anything on the mainline and it's only travelling about three-
quaters of a mile anyway.

It's not a matter of the tube trains hitting lineside structures, it's
a matter of what you're going to use to get a defective 1992TS off of
the line when it can't move itself...

What do you use to move a failed D78 on the Richmond branch or a l65 on the
Amersham line?

Somebody probably goes and finds a barrier coach. The DC lines once had
them to allow standard stock to mate with Oerlikons, to allow the
latter to push the former out of the way. I haven't a clue what they
use nowadays.

Probably nothing as methods of dealing with failed trains have developed.
It's extremely rare that an EMU can't be got moving under it's own power
albeit on reduced power.

Battery loco from Lillie Bridge or Acton Town?

The control systems on a D can be split in half, so that if there is a
failure on one the other can get the train back to depot. Even on LU metals
the need for an assisting train is extremely rare and only due to a
catastrophic failure.
