>>980557Helsinki. To be fair, much of the tram network is on major streets that may even become quite congested. Most of it is now on concrete slab, but some areas remain where it is just laid on the ballast in the old school way, but even then the track bed is covered with sand. I guess that makes easy cleaning too. I wouldn't mind about the east German style railroad track but it would be a trash magnet.
But yes, the emergency vehicle argument is getting ridiculous. Like this Bridge we may have, the foamers have spotted from the project plans that it too would have the track bed in concrete and with grooved rails. It makes no sense (or at least, there would be like one fire truck or ambulance for every 100 joyriders) and may inflict unnecessary speed limits to the bridge, as you can't have guard rails.
