Trains no longer waiting for pulling-up train
In message . com, Neil
Williams writes Is it really necessary to stick strictly to the timetable if you're running a service as frequent as every 2 minutes? Surely you'd just feed the trains "into" the system at roughly the right frequency from each end, and keep them moving as quickly as possible. I'd agree, though, that if the service is really that frequent holding connections is probably counter-productive. Basically yes it is. As the trains are diagrammed to run at certain times, so are the drivers scheduled to be in certain places at certain times to drive these trains. Where branches are involved, you also have the issue of the trains not arriving at the junctions at the wrong times - causing that old chestnut, 'blocking back', thus delaying the service further. It can take over 2 minutes to get a train through a junction and ready to accept the next train. Once a driver ends up being more than 5 minutes late off their first half, by the time they've had their statutory half hour meal break (which they are not paid for and therefore is their 'own' time), they are then potentially late for the second half of the duty which then causes more delays... and so it goes on. -- Steve Fitzgerald has now left the building.
