Post by eastenderCan I buy a return from and back to the last station on the Freedom Pass
limit and start journey from an earlier stop provided the train stops at that station?
Yes, you can, and the train doesn't need to stop at the boundary zone
station. But most ticket machines and ticketing sites fail to offer the
option. However, c2c is an honourable exception, and the journey doesn't
need to be on its trains. Manned ticket offices should also offer them.
