Most Tube station and all DLR station ticket machines (except at Lewisham, Woolwich Arsenal and Shadwell from Monday 10 August) are only accepting bank cards. You can top up using your contactless and Oyster account, the TfL Oyster and contactless app or an Oyster ticket stop. Ticket machines at all London Overground stations are still accepting cash.
Metropolitan Line: Severe delays between Harrow-on-the-Hill and Amersham / Chesham / Watford while we fix a signal failure at Moor Park. Tickets will be accepted on Chiltern services. GOOD SERVICE on the rest of the line.
