LU are implementing a metro style ATO system (whether they should have used
one of their existing implementations is a different argument).Given that
there is no working ATO system on the national system, why try and claim
that
there is? The system which they are implementing will at least talk to
trains
with the Chiltern ATP system.

When the SSL upgrade was being planned, was any thought given to handing the
Harrow - Moor Park fast lines, and the entire route and service to Amersham
and Chesham over to Network Rail and Chiltern? There would be disadvantages
(e.g. no through trains from Amersham to the City) but simplification should
give a more robust service.


If the Wycombe route ever becomes part of HS2, or Crossrail,
Transferring the Met. fast lines, north of Harrow-on-the-Hill, to
Chiltern, would seem to be the way to go. One cannot imagine Amersham
and Chesham commuters are thrilled with S8 stock. Moreover the
plethora of signalling systems is, almost, destined to induce failures.
