Brading will require new signalling, signals, point machines and train absence detection (track circuits or axle counters). It might be sensible to use axle counters for the short single line sections to St. John’s and Sandown and eliminate tokenless block. Given the age of the signalling from 1960’s(?) maybe even resignal Sandown (and even Ryde St. John’s to Pier Head?) to the same standard. Modular signalling would seem ideal.
