The answer is that the line is fitted with TPWS as well as the
LUL trainstop system. At each signal, there is a TPWS loop and a
trainstop.

I thought there might be something like that. I'm also guessing
that it would be illegal to have tracks not equipped with some sort
of redundant saftey system in potential revenue service.

I thought TPWS was installed on a risk-of-SPADs basis, so not on all
stretches of all passengers lines?

That is correct, in fact a number of TPWS installations are being removed as
some overkill occured during the original fitting.

Yes. But the service trains that use it a

If I'm staying at my mother's I should be able to hear them.

Does that mean that AWS is then counted as the redundant safety system?
Or is even that not necessary? After all, not all lines have AWS.

The NR trains operate at lower speeds due to less responsive braking

That was one of the reasons that I thought the speed restriction would be
lower, assuming that there was no redundant system for BR trains between
East Putney and Wimbledon.

Alongside the down platform at Southfields there is newly installed NR
signalling equipment visible. Clearly renewals are to a NR design, whoever
is actually doing them...

What is that, signals with only two lenses that use LED lamps?

No, just electrical boxes with the same 'over engineered' supporting
framework in the current NR style...

Been on the late trains a few times plus have also seen them crossing
over the Upper Richmond Road, aka the A205 South Circular - hardly a
quiet backwater!

There was (at least within the last year or two) an empty working or
two leaving Waterloo between about 0930 and 1000. Such things ought
to be easier to spot.

Yes so have I,

I don't know, but my guess is that it would have to be one or the other in
order to safely and legally operate NR trains in revenue service.
