So your claim that "Sunset 3d Rail have lots of small engines" is retrospective.

I don’t understand what you mean by retrospective. I’m not claiming anything. Look through eBay and the encyclopedia that Brass Trains.com and you’ll find many small engines they have done and are available on the second hand market. If you’re trying to get a “rise out of me”, you won’t. LOL

“There was a fellow on what forums? Who is this fellow?“

His name escapes me as he changed it all the time. I think it was Hal and he always added something to it like Cactus Hal or Engineer Hal  or some such nonsense. He was pretty obnoxious.  He had a loop of track on a board that had a bunch of what I think were fiberglass garden rocks and sand. One thing that he kept harping on about was Walschaerts valve gear. Couldn’t have a locomotive with it!  Have seen him post lately anywhere so he’s either died of has been tossed off all the forums. Scott Mann lists the minimum radius for his 2 rail 2-6-0’s at 48.

You can always hit the "report" button.

Peter, a main rod connects the crosshead with the main driver crankpins.  Your photo shows a two piece side rod.  That does allow lateral motion, but so does a solid side rod if there is a tiny bit of clearance on the crank pins.  Real side rods are articulated at a clevis, usually off the crankpin a bit.
