Streetcars were the primary way to move around Saskatoon and Regina for the first part of the 20th century. The cars were attached to overhead electric lines and ran along a rail system through downtown in both cities.
Saskatoon, SK is of comparable population size to St. Louis, MO, and the latter has 2 light rail lines. It can be done again, and it seems the bus demand is there at least.
Just don’t hire whoever designed the LRT system for OCTranspo (Ottawa), or the Eglinton Crosstown (Toronto)
Car-centric city building took off in the late 1940s, and like many, many other cities, Saskatoon decided to dismantle their streetcar system in favour of having a couple extra lanes for car traffic.
Mid20th century many cities got convinced to phase out electric trolleys in favour of diesel-burning, tire-tread-shedding busses. And there were no negative consequences!
The streetcar rails are still under the asphalt in Winnipeg. You can see them when the potholes are really bad lmao
