Shay N XL L M4

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…

EMD 16-567D1 2EXH NT N XL L M4

The 567 prime mover is a line of medium-speed diesel engines manufactured by GM Electro-Motive Division. They were used in many EMD locomotives from 1938-1966 when it was replaced by the EMD 645. The 567 proved to be exceptionally successful in passenger, switching, freight, marine and stationary services. The 16 cylinder 567D1 variation could be found in the following locomotives:

FL9, GP18, GP28, SD18, SD28

Heisler N XL L M4

The Heisler locomotive was the last variant of the three major types of geared steam locomotives.

Charles L. Heisler received a patent for the design in 1892, following the construction of a prototype in 1891. Somewhat similar to a Climax locomotive, Heisler's design featured two cylinders canted inwards at a 45-degree angle to form a 'V-twin' arrangement. Power then went to a longitudinal drive shaft in the center of the frame that drove the outboard axle on each powered truck through bevel more…

Dual CAT 8-D17000 N XL L M4

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…

EMD Dual 16-645E3A 2EXH T N XL L M4

The Dual EMD 16cyl 645E3A prime movers were used in Union Pacific's DDA40X locomotive. Each of the two prime mover provides 3,300 hp. The DDA40X is the most powerful single-unit locomotive ever built.

As the DDA40X program was a test, a number of experiments were conducted during the service life of these locomotives. One such test included fitting a few of the units with air raid sirens to warn track-side personnel when away from grade crossings, but the results were inconclusive. Another of more…

Cooper Bessemer 6-FW-6-LT N XL L M4

General Electric produced the 70-ton switcher as a complement to its 44-ton model. The idea behind the development of the 70-tonner was to provide a locomotive suitable for branch lines, switching and transfer service. To be a success, the locomotive had to satisfy certain criteria. It had to be:

• Light enough to run on 50-pound rail and light bridges,
• Powerful enough to move long cuts of cars in switching or road hauls.
and
• Fast enough to make light passenger runs.

The 44-tonner could more…

EMD 16-645E 2EXH NT Ed3 N XL L M4

The EMD 645 family of diesel engines were designed and manufactured by the Electro-Motive Division of General Motors. The 645 series was an evolution of the earlier 567 series and a precursor to the later 710 series. The 645 series engines entered production in 1965. All 645 engines utilize forced induction, with either a Roots blower or a turbocharger. The 645 series has a maximum engine speed of between 900 and 950 revolutions per minute (rpm), an increase over the 800 to 900 rpm maximum more…

EMD 16-645E3B LATE EXH T Ed2 N XL L M4

The EMD 645 series engine was an evolution of the earlier 567 series and a precursor to the later 710 series. When the 645 prime mover entered production in 1965, a large series of new locomotive models were introduced. The turbocharged version was used in EMD's 40 Series (GP40, SD40 and SD45) in 3,000 horsepower (2,200 kW), sixteen-cylinder form and in 3,600 horsepower (2,700 kW), twenty-cylinder form. EMD also introduced the Roots-blown 38 Series (GP38, SD38) and turbocharged, twelve-cylinder more…
