My children have Oyster Zip cards. We're travelling into London tomorrow. We plan to get the 9:32 train, so off peak, just!
Daft question but do we need to wait until the clock turns 9:30 before they tap their Oyster cards at the stations and then race down to platform for train in order to get the off peak fare or will we still get the off peak fare if we tap when we arrive as long as the next train due at the station is after 9:30?
