I sign Basingstoke except for P5 as we cannot be routed into it, Salisbury drivers might sign P5 though. At Clapham I only sign platforms seven to eleven, I don't sign the Southern or Overground lines nor the 'Windsor lines'. As a guard our route knowledge includes, platform lengths, dispatch procedures, location of disabled access points, location of signals and associated banner repeaters or OFF indicators, knowledge of which stations are not accessible to mobility impaired passengers is another important point so we don't strand someone on a platform.
