Now for the obvious question - do you have a list of those four
stations? Presumably if a person starts their journey (and touches in)
or ends their journey (and touches out) at one of these four trial
stations but has failed to touch-in/out at the other end then the £4
charge applies.

I saw the poster at Surrey Quays on the East London Line the other day.

According to Paul C in another part of this thread:

Aldgate, West Ham, New Cross, Stepney Green, Upney are the LUL trial
stations.

Westferry and Tower Gateway are the DLR trial stations.
