My favorite debate:
What the Fuck is Light Rail??
Because it is fascinating how we have a whole class of train that isn't a tram but it can run in the street but it also has dedicated Rights of Way Usually and can even run on elevated tracks but it's also not an elevated metro and like people will call any local train a light rail when it's not
Good question, it’s a thing that exists but defies a concrete definition, you can see it and say that system is a light rail but there is no real definition of Light Rail beyond the kind of vehicle it uses
