| CoolspringPowerMuseum "Stationary gas hit and miss engines, throttle governed engines, flame ignition engines, hot tube ignition engines, and hot air engines are all among the permanent exhibits at the Coolspring Power Museum in Coolspring, Pennsylvania. Engines in the museum's collection range in size from fractional horsepower up to 600 horsepower." |

Photo courtesy of Coolspring Power Museum "Among the operating engines are a 1902 Harvard-Stickney 3-hp single-cylinder farm engine (unusual, mass marketed by Sears-Roebuck), a 1895 Climax 50-hp flour-mill engine (with disc crank and pendulum governor), a 1885 Schleicher-Schumm 2-hp engine that was the American licensee of Otto and is the second oldest operating engine in the United States, two of the four known surviving Westinghouse vertical engines (dating from 1901, one of which is operational), a 1901 National Transit Klein Model 5 (John Klein's last engine, with a "masterpiece" pneumatically operated variable cutoff governor), and a 1927 Busch-Sulzer 400-hp four-cylinder vertical air-injection diesel (from the first American diesel manufacturer)." |
Chris Austin posted a photo and a video with the comment: "Here are two gas (natural) engines DC generator sets built by Westinghouse installed in the Wheeling Blaw-Knox rolls shop. These are were donated by Blaw-Knox back in the late 80's I believe, and are currently both in running condition at Coolspring Power Museum , Coolspring, Pa. Do any of you old timers remember these engines?"
Chris Austin: These were used for stand by DC power up till plant closing time.

| CoolspringPowerMuseum "Exley Station houses Coolspring’s headliner, the 600 hp Snow engine. Built in 1917, it spent 75 years pumping natural gas and was donated to the Coolspring by National Fuels in 1992. Its a two-cylinder (plus a gas pumping cylinder) but the pistons are in tandem, one in front of the other and double acting, firing on both sides of the piston. The two power pistons are 24 inches in diameter and the gas pumping piston is 18 inches. The gas piston takes natural gas at 50 psi and compresses it to 450 psi for delivery to the combustion chambers. The stroke is 48 inches so the power pistons displace 86,800 cubic inches. Torque is 31,512 lbs-ft at 100 rpm. The 140 ton Snow was removed from the National Fuels Royston Station in 10 ton chunks by museum volunteers and stored until the building project could be funded. Reassembly began in 2006 and the ceremonial startup happened in 2014." [DieselWorldMag] |

| DieselWorldMag "This brute, and we mean the Fairbanks-Morse 38F5-1/4 engine not the bushy-haired Mike Murphy, is one of the favorite runners in the museum because of it’s unique sound. It’s one of F-M’s legendary two-stroke OP (Opposed Piston) engines that went into production in 1937 and eventually built in many sizes, outputs and configurations. Four cylinders containing two pistons in each and driving two crankshafts, one above one below. The Model 38 type is probably most famous as a submarine diesel. The 38F5-1/4 (5.25 x 7.25 bore and stroke) engines debuted in 1939 were the smallest in the Model 38 line. It makes 300 horsepower at 900 rpm and mounts a 200 KW generator. It was used on the R.J. Reynolds estate on Sapelo Island, Georgia, until power lines were run from the mainland. The engine was rescued in the mid 2000s by a group of Coolspring volunteers, saving it from the scrappers." |

| DieselWorldMag "This is a 3/4-scale replica of the Otto-Langen free piston atmospheric engine that took the world by storm in 1867. The practical application of internal combustion pretty much started with this engine. Wayne Grenning built the replica in 2000. It’s a runner and on display in the Susong Building, along with several other original engines on the American branch of the Otto family tree dating back to the late 1800s." |
