I think James meant that as the Kingston and Hounslow lines are loops, they run "Waterloo to Waterloo", without any other terminal at which they can stand for any length of time. For good timekeeping you need to have a little slack in the schedule, or else you end up like EasyJet flights, getting later and later all day. Trains to (say) Shepperton or Chessington can stand a few minutes at their outer termini, but the loop lines have no outer terminus and thus must be scheduled to stand a little while at Waterloo. This reduces the number of tph you can operate out of each platform there.Generally, too, you need to allow a longer sslack time for longer-distance trains, since they are more likely to lose more time en route. This probably helps Fenchursh Street's figures, since none of its services goes very far. |
