Green Steam Products is a model railroad supplier that has served hobbyists since 1996. The business began with three products: an optical train-detector module, a grade-crossing-signal flasher module, and an LED HO crossbuck signal. Its range has since expanded to cover the equipment and materials needed to build and operate model railroads.

Products include electronic-animation modules and supplies, DCC systems, decoders and accessories, operating signals, locomotives, rolling stock, track, turnouts, and cork roadbed. Green Steam also offers knuckle couplers, metal wheels, trucks, slow-motion switch machines, scenery materials, scenic accessories, and tools. Its signal and crossing-related offerings include products from other makers, such as hand-built lineside signals, servo actuators and decoders for crossing gates or semaphore signals, and grade-crossing bell modules based on recordings of real bells.

The company’s selection supports both layout construction and operating features, including train detection, signal control, and realistic crossing effects. Green Steam Products presents itself as a source for model railroaders seeking practical electronics, operating accessories, and essential layout supplies.
