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...
