The Hornby Rivarossi HO Scale 2-Truck Heisler is a replica of one of the famous American geared steam locomotives. The Heisler was designed in 1891 and patented in 1892 by Charles L. Heisler. 850 were built with the last delivered in 1945. This detailed model features a flywheel-equipped drive mechanism, a five-pole skew-wound motor, working headlight and magnetic knuckle couplers. This locomotive is equipped with a sound and DCC decoder. Like the prototype, it′s ideal for handling curves slightly sharper than 15′ radius, and RP25 wheels will handle Code 70 and larger rail. The 2-Truck Heisler is part of the line of Rivarossi/Hornby HO trains.
