Steam & Excursion > Largest cylinders on a simple locomotive?Date: 02/01/23 12:27 Largest cylinders on a simple locomotive? Author: timz I assume the VGN 2-10+10-2 had the
largest cykinders of any steamer, but how about simple engines? Simple question, and you'd think we'd know the answer. I would have guessed the SFe 2-10-4, but turns out another engine beat it.

about tied with the SFe 2-10-4, in second place maybe. Date: 02/01/23 16:12 Re: Largest cylinders on a simple locomotive? Author: wcamp1472 Large pistons vary as the inverse of the boiler pressure,
or, the pressure sent to the second stage of a compound locomotive. Large pistons also increase the mass of reciprocating engine parts.. Meaning that you can expect corresponding increases in driver counter weights, etc., rough riding, and increased wear-rates on the entire drive-train. Whirling, heavy counterweights are a big problem at high driver RPMs, and also a bigger problem, with small diameter drivers. Large pistons don't show me much, except that they're designed for low operating pressures, and low speeds..... W. |
