This is a HO Scale (1/87th) model of the frame and underbody of a CTA 4000 series rapid transit car. This uderbody is compatible with the Baldie and Plushie 4000 series shells offered in my store. The frame contains some of the major details present on the prototype from including the group switch, air compressor, and resistance grid box. The frame also has bolsters with a 1mm diameter hole in the center for easy mounting of trucks to the frame.
