“Who still has trollies besides San Francisco?”
I don’t know of any city with an actual trolley system. Modern light rail or streetcars are multiple axle and they often function in multi-unit consists and are often inter-urban transit.
Birney cars were an example of small, two-axle neighborhood trolleys that used to be common in the US.
