Helsinki is another place which co-ordinates streetcars with subways. Also the northernmost subway in the world, which I have ridden ― by apparently about 50 km compared to that of Petrograd! Not, however, the most northerly electric street railway, which is elsewhere in Finland, & which I have not ridden.
