Fair enough. But you've made me very curious to see a widely-agreed-upon list of which systems qualify as light rail according to a definition that excludes trams. (Wikipedia does not attempt to make any distinction -- e.g. https://en.m.wikipedia.org/wiki/List_of_tram_and_light_rail_...)

Edit: another example of Wikipedia not being able to agree with itself on a distinction -- https://en.m.wikipedia.org/wiki/Light_rail_in_North_America lists the Toronto streetcar system as "the busiest LRT system in North America" even though it's definitely a traditional tram system with mostly street-running. Below it calls it a light rail ('in the case of Toronto, actually streetcar').

Having played Mini Metro for over 100 hours, I can attest that a light rail and a tram are not the same ;)
