GE Cat-44 H0

The GE 44-ton switcher is a 4-axle diesel-electric locomotive built by General Electric between 1940 and 1956. The locomotives were available with a choice of prime movers. Most were built with a pair of Caterpillar Inc.'s D17000 V8 180 horsepower (134 kW) engines. It was designed for industrial and light switching duties, often replacing steam locomotives that had previously been assigned these chores. This locomotive's specific 44-short ton weight was directly related to one of the more…

FM 6cyl 38D H0

One of the last to enter the US locomotive market and one of the first to leave, Fairbanks Morse is a historical manufactur known throughout the wold for their renouned oppsing piston prime movers. Maybe best know for the FM Trainmaster locomotives, Fairbanks Morse is still in business today as a Producer of Marine engines used in ships and submarines.

Not many examples remain and only a few of those are operational in the FM locomotive line. Many of the locomotives that are still running are more…


The EMD F40PH is equipped with a turbocharged EMD 645E3 V16 cylinder, two-stroke Prime mover. A standard F40PH has a gear ratio of 57:20 allowing a top speed of 103 mph (166 km/h). To support passenger service, the F40PH has another electrical alternator known as the head end power unit.(HEP) The HEP unit generates three-phase AC power at 480 V AC, 750 A or about 500 kW to provide power to the passenger cars for lighting, heating, and air conditioning. Originally F40PHs all powered the HEP more…

MP40PH-3C H0

The MPXpress line of locomotives were the first production passenger locomotives to meet EPA Tier 1 and Tier 2 emissions regulations, as well as FRA safety regulations regarding crashworthiness and fire safety. Numerous public transit agencies in Canada and the United States have ordered MPXpress locomotives for their commuter rail services. To date only GO Transit have MP40PH-3C in Service but Sounder Commutr Rail in Seattle does have an order pending for 3 Units.

ALCO251 (16 cyl) H0

The Alco 251 diesel engine was developed by the American Locomotive Company to replace the 244 and 539. The 251 Prime mover was Alco’s best selling prime mover. In 1954, the 251 went into production with the inline-6 at Auburn, New York. Ultimately a refined and successful design, the 251 outlived its designer. For a time it was built in Canada by Montreal Locomotive Works. Today it is still available from Fairbanks-Morse. Examples of the 16-Cyl 251 can be found in the following more…

Big Boy 4-8-8-4 H0

During the late 1930s, the Union Pacific often used helpers to move trains from Ogden to Wasatch. The UP wanted to simplify this move so they asked their "Department of Research and Mechanical Standards" (DoRMS) to design a locomotive that could pull a 3600 ton train unassisted over the 1.14% grade of the Wasatch.
The designers determined that to pull a 3600 ton train, a tractive effort of 135,000 lbs would be needed. Assuming a factor of adhesion of 4.0, the weight on drivers would have to be more…

Shay H0

The Shay locomotive was the most widely used geared steam locomotive. The locomotives were built to the patents of Ephraim Shay, who has been credited with the popularization of the concept of a geared steam locomotive.

Shay locomotives had regular fire-tube boilers offset to the left to provide space for, and counterbalance the weight of, a two or three cylinder "motor," mounted vertically on the right with longitudinal drive shafts extending fore and aft from the crankshaft at wheel axle more…

SP Cab Forward H0

Cab Forwards were designed to keep the crews from getting asfixiated from smoke while long tunnels. While a few other railroads considered purchasing the design, only the Southern Pacific Railroad ever bought any. Many wheel arrangements were used but most of them were of the 4-8-8-2 design.

Many Cab Forwards also contained a Seperate Air Horn. This Sound Profile also contains the ability to play this horn sound using Function 12. (remappable if desired)

AC-6 through AC-12 Cab Forwards Used more…
