Driving normal fixed frame locomotive on logging railways
was virtually impossible. The irregular underground made the wheels come off
the track and derailed the locomotive. One of the solutions to this problem,
among the more numerous Shay and Climax
was the Heisler.
The Heisler distincts itself by its V-shaped two cylinder steam engine, driving a central crank shaft which on its turn drove one axle of each powered truck. The other axle was driven through a conventional rod.

The model: Heisler "B", 2-truck and Heisler "C", 3-truck
In 2007 I stumbled over an online auction of both a 2-truck and a 3-truck version of the newly produced and reworked Heislers from Rivarossi. As the old model cannot compete with the new versions. RP25 wheels, nicely blackened wheels and rods, nice add-on details instead of cast-on details and better running quailties are the most significant improvements.
|The "pièce de resistance" of a 3-truck Heisler. For the rest the 2-truck and 3-truck version differ very little|
It turned out that both versions where coal fired. The box contained detail part to convert the loco to oil burners. To create more difference between the two models I converted the 2-truck version to oil burning
The coal burner version has a large stack with a voluminous spark arrestor
The oil burner has a fairly normal stack
|The coal bunker was removed||And replaced by an oil bunker.
This change suddenly gives the model a lot more "muscle"
