These very attractive trolleys were made by Lincoln Line of Chicago, based on the American PCC streetcar. They feature plastic bodies with extensive decals to create the doors and windows, and a metal floor. A trolley pole is added on the roof. They're floor toys, but having recently acquired a second one (the green one seen here) I've been thinking about retrofitting some trucks as the size is pretty good for O gauge. I've not been able to find much information about Lincoln Line out there, although they are covered in Kurt Resch's Collector's Guide to Bus Toys & Models, which advises they were made in the 1960's.
