Signalling & Track diagrams

[metrailway]

I've stumbled across some LU signalling diagrams for the Northern and Jubilee Lines before their upgrade to ATO on the FOI site whatdotheyknow. I have also found some track diagrams as well for the whole network.

Apologies in advance if they have been posted on here before.

Hmmmm, interesting that the junction diagram appears to show the normal/reverse positions of points; exactly what was needed in the Ealing Broadway derailment!

These type of diagrams do these are for the controller but accessible on the internal network.

There are other diagrams which show what each signal needs to have before it clears also available on the internal network these do not show the normal lay of points. Hence the Ealing Broadway error plus Ealing Broadway was only showing the old layout not the current layout

Not that it would have made any difference; the offending set of points at Ealing Broadway were still there and would have still required securing under both old and new layouts.
