So why are there signal failures on the less than 10 years old Jubilee

Tubelines for the **** that they inherited, even if they should have
known what they were letting themselves in for.

Scientifically speaking, when you're talking about complex
electromechanical systems like train signalling, 30 years and 50 years
is Pretty Damn Old.

I notice that you didn't mention the less than 10 year old Jubilee
Line extension. I accept that the Victoria Line signalling is probably
knackered I just wish that all concerned would stop going on how the
probelms are all due to the "Victorian" infrastructure. The DLR is
hardly Victorian and the signalling and all the trains have been
replaced since it was built.
I can't wait for the first signal failure on the new Westinghouse
system on the Victoria Line and on the new Thales system on the
Jubilee Line.

But lots of the newer kit is bolted on to or "talks to" the Victorian
or kit from the 20's-60's!

There will be problems with the new stuff, as it won't be built to
last....- Hide quoted text -

Not on the Jubilee Line and that still gets problems.
