There is a real Berlin live map of subway, bus and railway at: https://www.vbb.de/fahrinfo/ by the operator.

Seems no english version available, you have to

  - click upper right corner "Livekarte"
  - click on the menu again "Livekarte"
  - select means of transport: radio buttons for subway, railway etc
  - zoom in to see subway

Note that this just interpolates the vehicles' positions based on their delay, which in turn is calculated based on periodic pings that the vehicle sends AFAIK. So the map does not show realtime positions in the same sense as e.g. HSL's trip planner does [1][2]. In fact, the location and speed of a vehicle can be very off.

Personally, I loathe this map, because it gives an impression of accurate data, even though it isn't that precise. VBB gets credit for providing supposedly reliable data, even though they could (and should, given amount of tax money spent) provide much better data!

[1] In the departures section on the left, tap on one of the upcoming departures to see the vehicle in realtime: https://reittiopas.hsl.fi/terminaalit/HSL%3A1000105?locale=e... [2] https://digitransit.fi/en/developers/apis/4-realtime-api/veh...
