I think I caught the Shay bug!
They are very interesting and way out of my price range!
I'll have to start dropping hints for my birthday!
Does anyone online have any good images of Shays?
Aaron drool drool drool pass the napkins
Don't be embarassed, you have to learn somehow , the term "shay" comes from it's inventor, Ephariam Shay (I think that's how it's spelled) The shay has three vertical pistons on the engineer's side of the locomotive which power a horizontal, flexible. driveshaft, also on the engineers side which powers all the wheels through gears.OK ... I'm a bit embarrased to ask, but what is the definition of a "Shay"?
Is it a generic term for a direct-drive (i.e., driveshaft and geared powertrain) loco, such as a Climax?
Other locomotives like the shay were the climax and heisler, could be one of those, or a shay They were all geared logging/mining/industrial locomotives.Funny thing, I have a really awesome LHS and they have a couple of these sitting in the display case. I often wondered what they were, I don't recall the description saying "Shay". I never asked about them (don't know why) but they look pretty cool. I think they've been there for a while because the price is marked down on them.
Well, if you haven't figured this out yet, the two cylinder shays were smaller, (narrow gauge?) I'm just guessing but the three cylinder shays were standard gauge, possibly with a few exceptions.SantaFe & Shaygetz,
Thanks for the definitions! Quite clear, though I'm intrigued to learn of the differing cylinder setups that were developed way back when.
So on a 2- or 3-cylinder true Shay, were all cylinders working off the same steam pressure, or was it more of a compound setup, with steam discharge from the first cylinder being introduced to the second, and so on?
On the Shay in the photos above, I'm assuming that the tender is articulated from the main loco, and yet still has wheels that are gear-driven from the main propulsion system? One connecting shaft with differentials on both ends ???
I've ridden the Climax (or its cars, really) at Clark's Trading Post in Lincoln, NH. That old girl certainly pumps out some power. The drive shaft / gearing underneath the frame is pretty impressive. I recall (vaguely) a small 3rd cylinder under the frame that operates a breaking system, too.
Thanks, guys ... interesting stuff!
