So you didn't read, or chose not to agree with, hwl's subsequent post 9003?Yes I did read your post a page or two back but chose to go with Gralister that sulphurous fumes in a damp humid atmosphere tends to become acidic and causes more corrosion to the overhead bar and connections than humidity alone.

As others have made clear, the operation of the circuit breakers are initiated by trackside permanent magnets, an example may be found in the Unipart rail catalogue here.As to balises at neutral sections, it is immaterial what they do. They still have to be installed at the neutral section at St Brides and are not additional to a temporary end of energisation as was implied in the original post about providing them.
