Oyster Card users were “overcharged” more than £60 million last year with rail travellers most likely to be hit in the pocket.
Passengers failed to swipe in or out on five per cent of all rail journeys last year — and were charged the maximum single fare of up to £8.30 as a penalty.
On national rail services into and out of London, there were 4.6 million incomplete Oyster journeys totalling £23 million in revenue in the first 10 months of 2013.
