even as small as 50 feet radius, was too slight to be noticed or measured in a model one-eighth full size. This construction of the trucks would allow a car 50 feet (15 metres) long to from a street only 28 feet (8.5 metres) wide into another of the same width. Passenger car The floor of the passenger car was a frame of C-channel beams of 5 inch (12.7 cm) gauge. It was 51.16 feet (15.6 metres) long, and 7.5 feet (2.3 metres) wide. The cylindrical car body was formed of hoops of light iron T-bars bent into a circle of diameter 10.7 feet (3.26 metres). The publicity emphasised the luxuriousness of the fitting out: The cars possess many novel features, both outside and inside. The circular section and rounded ends admit of the strongest possible construction, without an overweight of material. The framing of the body is filled in by panels covered with rich upholstering, which covers all the interior. The exterior is sheathed with paper and copper. While adding to the strength, this form is expected to diminish the wind resistance fully one-third. The interior of the car is light, roomy, and pleasing to the eye. The seats are upholstered like the rest of the car, and comfort and luxury have been carefully studied in every detail. At each window was a specially designed device for securing ventilation without the annoyance caused by dust. There is an entire absence of sharp corners, so that, in case of a serious accident, the liability of the passenger being greatly injured is largely avoided. There is no mention of any insulation, or of heating arrangements for winter. Despite the reference to copper sheathing, the surviving photo of the fire damage indicates that the metal used in the experimental car was cheaper, with a lower melting point. The car had two rows of horizontal rectangular windows down each side, with the frames fitted in between the hoops and attached to them. The ends had open platforms for entry and exit, with canopies, and passengers passed into the body of the car via swing doors with glass panels and spring closures. Lighting was by hanging oil lamps. There was a continuous run of padded and upholstered seating down each side, with backs resting against the curve of the cylinder. In addition, there was a line of swivel or barbershop chairs along the major
