I've come full-circle with Weaver. When I started with Weaver products, they came 2-rail and I had to convert them to 3-rail. Now when I get them, they're 3-rail and I'm converting them to 2-rail. Kind of ironic in a way.
This one arrived yesterday. Won it on eBay last week.
Two of six Weaver 57-foot Mechanical Reefers I had two-railed. Installed the appropriate Weaver-supplied shock-control couplers. I just ordered five more sets of couplers even though I don't have the cars to put them on yet.
Four Weaver 40-foot frameless tank cars -- "Sinclair Oils". Switched over the 2-rail wheels and Kadee couplers.
OGR Commemorative cars, one autographed by the OGR staff. All switched over to 2-rail wheels and Kadee couplers.
I have several more cars for which I don't have photos handy -- probably about 30-40 more in boxes at home. They're mostly hopper cars -- ACF center flow hoppers (the first ones I bought), PS2's and high-side PS4427 grain hoppers with a few Stock cars. I donated a couple dozen cars to the club layout several years ago because I wasn't using them, so they're now layout rolling stock that the members use when they want to run but don't feel like hauling a bunch of cars down.
