I love these maps. Here is one from Switzerland: https://maps.vasile.ch/transit-sbb/, just a tad bit busier than the US

UK (not a map, similar view to what the signallers see): https://traksy.uk/live/M+58+STIRLNG

Australia and New Zealand: https://anytrip.com.au/

(although it also includes some buses and ferries, and you can only look at one region at a time)

Yandex has it for (mostly Russian) trains that it has on schedule.

I love that the map doesn't show any borders
