Image and data from "Porter
Steam Locomotives Light and Heavy".
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 logs used for rail ("poles"). It could haul as many as 10 loaded cars. Note the size of the steam dome.
