Trainline.com? :-)

I don't think they do local fares. In any case I could just walk to Wanstead
Park and jump on the train and most of the time there's never a ticket
inspector to sell me a ticket en route.

The Trainline does sell local fares, as long as you book them far
enough in advance for them to be posted. And it probably is the only
option for the GOBLIN, unless you're actually going between Gospel Oak
and Barking ?or Blackhorse Road? (can't remember whether it's
integrated with LUL station or not).

I commuted on the NLL for a year (with a Travelcard) and saw a grand
total of two RPIs. Although sometimes the GOBLIN does carry uniformed
bouncers, these are to deter the lairy rather than the ticketless.
