Just heard on BBC London this morning that service is still
suspended.

According to TfL this is now due to signalling problems affecting
the entire Northern line.

LU have been blaming the tripcock problem on the "signalling system"
from the start.

Another question: what, if any, differences are there between the
tripcock systems on the 1995 (Northern) and 1996 (Jubilee) trains, which
are generally of similar design from the same manufacturer?


I think it has to do with the company that maintain the Northern Line
stock, who are different from Jubilee Line stock maintainers.

They are both maintained by (Tubelines) Alstrom. The diffrence is that ILRC
is the Northen line was a Alstrom design and build and the Jubliee line was
a LU design and Alstrom build. Therefore despite them only being a year
diffrent in age 95 Nor 96 Jub there are signifcant diffrences.
