Along with delayed trains, ticket queues and slow-walking tourists, paying to use the loo is one of the most frustrating things about mainline London rail stations.
But passengers will be relieved to hear that charges are being suspended at Victoria and Charing Cross, two of London's busiest stations, in changes just announced by Network Rail.
'[We have] stopped charging passengers to use the toilets at Victoria and Charing Cross. This brings those stations into line with London Bridge, which has not charged since the new concourse opened, and Cannon Street, which has not charged for some years', said a spokesperson.
Last year passengers spent £12.8 million at Network Rail’s toilets, and in 2014 Victoria alone bagged the rail authority £600,000.
Finally, you can spend a penny without, y'know, actually spending a penny.
