Just seen a piece on my local TV news programme, and apparently South West Trains are running an experiment, in combination with Network Rail, where if there is some kind of "incident" that needs attention that would delay trains, like a track problem, or a lineside fire, the BTP drive them where they need to go with their lights flashing and sirens going. The idea is to get problems resolved sooner and therefore shorten delays. If this experiment is successful it will be rolled out across the country. Thoughts?
