Are there 25 kV AC lines in Britain besides the CTRL?

As the subject line says:

To elaborate, the British network uses 25kV AC as its standard overhead
system. The only exceptions are our tram and light rail networks, some
of which co-exist with the national rail network (e.g. the Tyne and Wear
Metro between Pelaw and Sunderland).

There are also electrified areas that use 750V DC third rail (mainly
south east, and Liverpool) and the London Underground uses a 4th rail
system.

What system(s) are in use in Germany?

Clearly you are with that warm welcome.

Having read about the Eurostar trains which had to run on 750 V= on
English soil, I originally assumed that this was nationwide.

15 kV AC with 16,6666... (two thirds) Hertz. The same is used in
Switzerland and Austria, which makes it relatively easy for German ICE
high speed trains to reach e.g. Zürich or Vienna.

Tramways and Underground systems are different, as are also the two
oldest metropolitan railway networks (S-Bahn) in Berlin and Hamburg,
which use a 750 V DC third rail system; the same applies to the Berlin
underground (U-Bahn) which actually consists of two technically
incompatible networks with different gauge and opposite polarity of
the third rail (on one it is plus, on the other minus). More recent
S-Bahn systems like in the Munich or Frankfurt area run the same
system of power supply as the regular trains, i.e. 15 kV sixteen two
thirds Hz DC.

Was one network the west german system and one the east german?

and Switzerland. Excuse me for forgetting the Scandinavian
countries.

Do the Danish railways use 25 kV @ 50 Hz on all electrified lines,
or do other electrical systems exist there, too?

As you may know, that ends on November 14, when the new (25kV 50Hz)
line to St Pancras opens.

An eighth was 6.6kV 25Hz, and a ninth 6.6kV 50Hz (both Lancaster -
Morecambe - Heysham).

Arguably, the autotransformer 25kV - 0 - 25kV sections are a tenth
system.

Other historical systems are the City and South London centre third-
rail, and the Great Northern and City twin outside rails.

I believe so. However, it may be desirable for future extensions to
be 25kV overhead, given that 313s will be available soon.

Germany was changed from 16.2/3 to 16.7 Hz about 10 years ago.
