How does daily capping work on the Tube/DLR/London Overground/Tramlink/trains?
It depends on when you start travel (peak/off-peak) and in what zones you travel. Daily capping off-peak by Tube, in zone 1-2 is set at £5.10. Every journey in zone one is £1.60. 3 x £1.60 = £4.80, so when you make your fourth daily journey by Tube you will only be charged 30 pence and after that nothing at all until 04:30 the next morning.
