Beautiful model. But isn't the body actually a Cable Car?

Yes it is cable hauled, but is called (apparently) a streetcarBeautiful model. But isn't the body actually a Cable Car?

If it grabs the cable through the slot, cable car... there are some old cable cars that have been motorized to run on the street, but only cable cars run on the cable car tracks (with the slot between the rails).

In most of my 3 point compensation applications I use a central pivot, you could add a brass bearing if you felt the mechanical need. A pic below shows my crude method on a Gauge 3 Wagon. For removal of the axle I solder some brass rod to the bearings at the outside, then cut to allow the axles to drop out. I then push a piece of wire to hold the axles and bearings in place.To overcome my issues and understand my traction problems I started a thread on Bogie Construction, which provided lots of ideas guidance and advice, with the two main potential issues to traction being Sprung Compensations on the axles and Drive to both wheels. To enable these I decided to build a bogie chassis with inside frame, which would later have dummy bogie outer frames.
The bogie frame made with 0.080" brass sheet, commercial frame spacers, and Horn Bl;ocks with Sprung Compensation, and Delrin chain drive. It has taken some time due to domestic duties, and waiting for parts, but I assembled it yesterday, and the bogie ran, so temporally attaching the Streetcar I gave it a run including my 1:24 gradient, and there was NO wheel slip. Of course other issues that I suspected would manifest themselves, did, but these were poor judgement calls on my part and are easy fixes, the good point is it worked:
The original bogies that I wish to emulate in looks, and a rough drawing:

A view from underneath showing the compensation and my messy (but effective) soldering:

Wheels removed to chemically blacked the frames to make them less visible through the dummy frames

The dummy frames are almost complete however due to the bogie pivot being behind the motor, I am in the process of devising an assemble method which will allow easy(ish) disassembly.
