It's super smooth on Chrome, but it's doing (say) 1 frame per second on Firefox.
It's getting choppy for me in Chrome when enabling the S and U Bahn mode

#52Nice! Would be more realistic (and more Mini Metro-like) if the trains actually stopped at the stations though. Also, the trains don't have to disappear and reappear at the terminal stations, they could just stay there until they are scheduled to go back - after all, that's what they do in reality as well... Any chance that the source could be made available ;) ?
Strangely S-Bahn does stop at stations, U-Bahn does not.
Maybe a difference in the source data?

#53What's the purpose of animation here?
It seems to have no information about actual train position, or am I missing something?

#55There 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

It's definitely a website bug, as goes from 1 FPS to smooth if you go to S+U and back to U again. (debugger didn't help, but it's all minified anyway)
The slowness in firefox comes from the station name drawing.
Going from U to S+U and back again seems to reset the setting for drawing them.
The settings option for drawing the station names is somewhat buggy.
To optimize this the text should probably be drawn to another canvas/surface and layered behind the main one and not be updated that often.

#58The problem with Berlin is than there are many operators for public transport by train:
* U-Bahn, for the subways (underground & aerial)
* S-Bahn, for sub-urban lines (mostly aerial)
* Traway in est-Berlin
A map, live or not need at least to combine the U-Bahn and the S-Bahn, (and if possible the tramway too), because you generally need to use both networks (with the same ticket) to travel. Staying in only one of the network is just not practical.

Thanks! I used the search to find it but always got to the German version.
