the Snow- 600 hp gas engine at Coolspring Power Museum

"This engine was manufactured by the Snow-Holly Works of Buffalo, New York, in 1917. It has two tandem 24-inch bore x 48-inch stroke cylinders that are double-acting. Fuel for the engine is natural gas with make-and-break igniters providing ignition. Total displacement is 86,800 cubic inches, or 1,423 liters. The rated output of the engine is 600 hp at 100 RPM, which yields a torque value of 31,500 foot-pounds.
The natural gas compressing cylinder at the front of the engine was also manufactured by Snow and features an 18 inch bore and 48 inch stroke. The compressor accepted gas at approximately 50 psi and raised it to 450 psi. Upon peak compression, the gas in the cylinder exerted a force of about 114,300 pounds on the piston.
At 75 feet long with an 18 ton, 18 ft diameter flywheel, this acquisition is one of the largest gas engines ever to be preserved in running condition. The overall weight of the engine is estimated to be about 140 tons."
Note: This engine is owned and operated by the Coolspring Power Museum, and the above information was provided by them.

If you listen carefully, you can hear the pressure sound of the gas filling in when the intake valve opens, and then the sound of the exhaust valve opening.

An impressive old machine in action. Wonderfull to see... 🙂

I've never seen a machine like this. What a unique sound! Thank you for sharing!

This video popped up today, I was just thinking about a 600 snow this morning! Oh my god. of all things! What are the chances, glad to see it still doing its thing! My two year old neohew is a gearhead like me and loves old trains and engines, maybe one of these days I'll get to take him there!

What would this monster have been used for? First things that come to mind is mining and power generation

[@aaronwilcox6417]

Yes. Old mines used engines like this for mine hoists and compressors to create air pressure for drills. They also used air driven muckers and track equipment to transport rock.

@thomas7529 They were used primarily for pumping natural gas along pipelines. At the far end of the engine is a compressor head, within which a double-acting piston pressurizes inflowing gas to 450 PSI and sends it down the pipeline to the next pump station. It was not uncommon to see 6-12 engines like this aligned in a row in those stations. The natural gas was also the engine's fuel source!

Sounds like an AT-AT walker
