Low Floor – Nothing New!
You would be forgiven for thinking that a low-floor transit vehicle is a recent invention – it was in 1992 that the first New Flyer D40LFs were delivered to the New York/New Jersey Port Authority. (The vehicle had been offered in 1991 after three years of development.)
But no! In 1913, BC Electric took delivery of Car #500 – a low floor streetcar.
Again, New York was a pioneer in the introduction of an accessible easy-to-board transit vehicle. Typical streetcars required passengers to step up to a floor over two feet above ground. The reason for this was quite simple and applied equally to buses produced before the D40LF: Virtually all mechanical and electrical components were below the floor. Streetcar operators believed that a low floor car would speed up boarding and alighting times and be safer for the public.
The “stepless” streetcar featured a floor just 10 inches above the ground. Two New York Railways’ engineers drew up the design. Frank Hedley was the General Manager, and JS Doyle the Superintendent of Car Equipment. The Hedley-Doyle streetcar featured a flat sloping floor. The electrical and mechanical equipment was redesigned and repositioned – resistors and compressor were moved into the motorman’s cab. The prototype was introduced in Manhattan in 1912. It appears to have been a success since more such streetcars were ordered from the car’s builder, J.G. Brill. The BC Electric Railway ordered one and numbered it 500. It was delivered in 1913.

There is a report that the trial lasted only two days before being abandoned. What went wrong?
Probably it was found to be incompatible with Vancouver’s trackwork – especially on hill sections where the 10” floor clearance would present problems. Too, the trucks used would have been problematic on some tight curves. As can be seen from the interior drawing and photos, the flat floor extended to the ends of the car where there was a raised motorman’s cab. Much like a D40LF, this raised area allowed mechanical components -in this case the truck – to be placed under it. But in the streetcar, a portion of the truck had to be located under the passenger compartment. To build-in adequate clearance, a semi circular bench seat covered the truck wheels nearest the centre of the car. But even this was insufficient, and the designers resorted to the use of the “maximum-traction” truck.
A normal truck has two axles, with wheels of equal diameter. The “maximum-traction” truck has one axle equipped with small pony wheels. The theory is that the weight of the streetcar is shifted to the larger diameter wheels, giving better traction. This design was a passing phase, the cars often derailed because the pony wheels carried very little weight.
New York Railways persevered with the design, even modifying it to a double-deck design. But by-and-large, those street railways that purchased the “stepless” streetcars (including two in Australia!) disposed of them within ten years or so.
