HO Class D 4 Truck Shay Locomotive, Unlettered, Black with Paragon 4

Overview

Class D Shays had three cylinders and four trucks, and weight of 100 and 150 short tons. They were no more powerful than Class C, but had greater fuel and water capacity, resulting in improved adhesion.

The distinguishing feature of the Shay locomotives was their unique geared drivetrain, which allowed them to deliver high tractive effort and excellent pulling power on rough and steep terrain. This geared drive mechanism used a series of gears and drive shafts to transfer power from the steam engine to the wheels. The gears increased the torque available to the wheels, making them well-suited for hauling heavy loads and navigating challenging terrain. These locomotives were particularly popular in the logging industry, where their ability to negotiate tight curves and steep gradients made them ideal for hauling heavy timber out of rugged and remote areas. The Shay locomotives also found use in various other industries, such as mining, construction, and sugar plantations, where their reliability and power were valued.

They stand as a testament to the ingenuity and versatility of these remarkable steam locomotives that played a significant role in the industrial and transportation history of the United States.

In the first production run, Broadway Limited is offering several variations of the 150-ton Class D Shay locomotives. They offer locomotives in multiple road names and paint schemes. Each of the models will be available with the newest Paragon4 Sound/DC/DCC sound system with smoke and integral GoPack capacitors. The models have die cast locomotive and tender bodies for maximum weight and tractive effort. See below for additional model features including the full list of individually controllable lights.
