No wonder the trains are overcrowded - even lazy foxes are trying to get on board cub-lic transport.
This wily beast didn't fancy walking back to his den, and hatched a cunning plan to bag a train from Woolwich Arsenal last night.
Traveller James Hollands took this sneaky snap and tweeted: "Even this fox is waiting for the train. I wonder if he wants to go swimming too?"
Reports the fox was travelling to meet a close pal in Catford are unconfirmed.
This is not the first time foxes have been spotted behaving eccentrically in London.
Last summer, a cash-strapped fox was spotted queuing at an ATM.
