I am just wondering for a debate in another group, is there a
restriction on electric locomotives on certain routes because of
limitations in the power supply?

There certainly are some routes that are or have been power supply
limited, notably the King's Lynn line. There may, though, be other
reasons for restrictions unrelated to power supply, though, so just
because a restriction exists, that might not be the cause.

And sometimes, freight companies don't want to pay what NR charges to
use electrified lines - supposedly why DB ceased to use its Class 90s.

It is a number of years ago now and may no longer be true but there used
to be one through train a day from Skipton to Kings Cross - under the
wires the whole route. However it was always an HST. When I queried this
I was told the the OHL from Leeds to Skipton did not have the capacity
to operate an electric loco, hence diesel power was used.

Still "No locos north of Milton" I think.

But that's not much of a problem because most freight trains would want
to go to Ipswich, Peterborough (and beyond) and Norwich, and none of
those three lines are electrified.

Presumably the Southern area 3rd rail network as unless I have missed them
no modern multi mode locos have been created to haul freight on any routes
so equipped, we have overhead 25.000V/Diesel and 25,000/Diesel/Battery
possibilities but none for third rail.

Indeed , I am guilty of over editing my own post . The original posting was
longer and would have mentioned them but also that for much freight work
such as container traffic to and from Southampton docks their lack of being
able to go the last mile off the juice makes them impractical,
no one wants to mess around swapping locos just to get in and out of the
container terminals.
That is why I mentioned the modern designs which can and with class 92’s
getting towards 30 years old describing them as modern is stretching the
point.

It certainly would be nice if the last few miles to Felixstowe could be
electrified but my suspicion is that the branch is used to heavily
that's it's not worth the disruption
