No, I bought a CDR - that was 6 quid (or 10 with a network railcard)!


I know what went wrong here. You bought a Stratford to Enfield Lock
"via London" CDR - i.e. for a journey that would have routed you via
Liverpool Street. What you really wanted was a Stratford to Enfield
Lock "not London" ticket for a direct journey, which costs the
slightly more reasonable sum of £4.10.

I'm guessing you purchased from a ticket machine, based on your
comments about the Network Railcard price of £10, which is something
would only ever be presented as an option to a passenger by a machine
rather than a human (i.e. a ticket clerk, though perhaps some are on
the edge of being robots)!

Yes.

One thing I'm wondering with hindsight is whether the return portion
of my CDR from Cambridge to London Terminals would have actually been
valid for a trip from Stratford to Enfield Lock? In the event, I ended
up going straight back home from Enfield Lock, changing at Cheshunt,
rather than returning to Stratford.
