Pole road lovo built by Robb Engineering Company (builder & designer) - Amherst, Nova Scotia, Canada - in 1903.
The boiler was tilted upward to help with water circulation and fire draught.
Two cylinders were mounted next to the boiler and at a similar upward tilted angle. They drove disk cranks which were attached to a shaft mounted below and perpendicular to the boiler. "This was spur geared, at a 4 to 1 ratio, with an intermediate shaft carrying chain-sprocket wheels, which drove the four carrying wheels by steel chains."
The four wheels were mounted on "sensitive springs". They were concave or double flanged with treads for gripping the poles
It could haul as many as 10 loaded cars.
Emile Stehelin (owner) - a French migrant lumberman who operated a 15 mile long "pole" railroad to haul logs out of his timberland.

Again by Robb Engineering Co Ltd - The locomotive “Maria Theresa” was built in 1897 for the W&NFR by Robb Engineering & Co., Ltd., Amherst. President D. W. Robb is seated at the throttle; standing behind him are Emile Charles Stehelin and (perhaps) Emile Jean, his oldest son. Although the locomotive is on iron rails in the factory yard, it was designed to run on rails constructed from wood logs, 20–30 feet long, squared on three sides and laid with the rounded side up.
