I would imagine that when TfL takes over control of
SilverLink Metro services PrePay will be introduced
fairly quicky. It would be quite easy to implement: most
of the NNL stations are self-contained or have interchange
only with LU, and those that aren't often have a clear
division between SilverLink and other services (e.g.
Willesden Junction, where SilverLink use the high level,
or Stratford where they use the low level).

When TfL take over the NLL, it will be cut back from Woolwich,
and the Stratford terminus will have moved.
