The table in the map booklet says that there may be delays on some lines and then gives other figures for particular stations. How do I use these numbers?
The main cause of delay will be getting onto trains that are very busy and getting into, or changing lines at, extremely crowded stations. The line delay indicates how much additional time you may need to get onto a service at the worst affected stations along that line. The delays for individual stations provide an estimate of how much delay you may face in getting onto a service at that particular station.
