Cab signalling would not work for NLL at the current time because

ELLX would have been a good route to try it on with all new trains,
but I think they decided the technology was not mature enough when
they had to let the contracts.

That could apply to the core route, but the extensions over NR
routes would have then required dual fitted trains, for the same
reasons as you point out for the NLL.

But a cab equipped train can run over non cab equipped lines (look at
Eurostar for an example).

Course it can, but why bother? Surely it is just a waste of money to have
cab signalling on a minority of the route. The interface between London
Bridge and New Cross signalling centres would presumably be more complex as
well - another expense with no benefit.
