Yes, but just with max. 40km/h

So that's why my train slowed to 40kmph when the Norwegian Telecom died for a few hours 3 weeks ago.

Yes, 40km/h is for driving on sight in most Europa. I think in France it's even 30km/h.

		In the UK at night it's walking pace. Literally. The guard gets out and walks and the train follows. (At least that was the case 25 years ago when I had a very slow train journey.)

Depends. For example German Zs1 (https://en.wikipedia.org/wiki/Railway_signals_in_Germany#Zs1...) would give them the full clear outside of stations.
