>>1473467Cities with first gen tram systems should generally keep older units running in regular service for teh lulz.
Here in Zurich there's the museum line that runs the last weekend of each month between downtown and the tram museum, but any regular ticket is valid, so you can just use it instead of a regular line. Ir even buy a day pass and ride the old trams all day going brrrrr.
In December on the Sundays where the stores open there's also a special downtown circle line using old trams. Comfy af.
