Incomplete journeys are currently charged at the maximum fare but TfL says in future the Oyster system will attempt to calculate the likely journey and charge the appropriate fare.
TfL say the change is intended to help passengers who occasionally forget to touch out at the end of their journey.
Shashi Verma, TfL’s Director of Fares & Ticketing, said: “The vast majority of customers use it correctly and are charged the right fare for their journeys. A small minority of rail journeys however are still not being touched in and out correctly and are being charged maximum fares.
“We don’t want to penalise customers who normally touch in and out for occasionally forgetting, so, for such customers, we are looking at ways of correcting journeys that have been left open without a final touch at the destination. ”
Caroline Pidgeon, Leader of the Liberal Democrat London Assembly Group, said it was “regrettable that the new system only addresses just one form of Oyster overcharging caused by people who occasionally forget to touch out. “
Pidgeon is calling on Mayor Boris Johnson and TfL to “address the much bigger problem of Oyster overcharging caused by the system not always working properly, for example when barriers are left open, or the machines are not working at the start of the journey.”
