I know that the rules for the DLR are not the same as the Tube, but what are the rules?
In the UK I have never seen a public bus system that allows you to take a (non-folding) bike on the bus. (There are long distance coaches that do allow bikes, however I am asking about local busses.) ...
Can I take a bike on the Tube (underground) in London, if so how much does it cost?
