no mention of any signalling alteration. I'm not clear what the comment re cannot be used anyway means - are they some o/o/u already, or just not accessible with 25/26 clipped?
That sounds very much like a mechanical locking overhaul. They should be done every 5 years but it can be extended with approval of the Route Asset Manager - Signalling depending on the results of previous annual checks.
