What freight used 3 axle trucks?

Trying to find out what kind of freight cars used the 3 axle, buckeye trucks? I know alot of the 250 ton cranes had them, tenders, some military flat cars. what other kind of cars are there used the 3 axles? Im trying to figure out if im going to try and do a kitbash using HO 3 axle trucks.

Not just Military flats, but all heavy duty flats, with high capacities could have them. Drop center flats too. There are a few in the Philly 30th st., yard northwest of the Amtrak station. I've also seen "whale-belly" tank cars, with them too. Haven't seen one of those, since the early 90's, they look like a regular tank car, with a giant "guppy" like belly, that drops between the trucks, and hangs towards the tracks. These monsters were also sprayed with insulating foam and had external head shields mounted on them, to make them compliant with FRA requirements for crashworthiness. I've never personally observed a boxcar, or hopper with those cantilevered trucks. They look like a regular truck, with slight modification, with another casting attached, holding the third axle. Three axle passenger car type trucks, I haven't noticed. Here's a shot of a six axled tank, although not a whale belly. Sometimes the loads are so heavy, they need two trucks per end, and ride on a span bolster. Here's one of those too.

look towards the bottom of the page, on the last link, and see a flatcar with 4 sets of 3 axle trucks under it.

Don't forget hot metal "Bottle" cars.. I'm sure that some of the six-axle ones used buckeye trucks..

Goldern Arm, forgot to thank you last night for those links. Great information. Especially helpfull with schnabel car builds.

Hot "bottle" cars? whats that?

Hot Metal cars...basically a "Bottle" shaped car that carries Hot Metal. Walthers makes a four-axle model but I have seen six- axle cars as well. There is a hot metal run that goes thru my area from East Chicago, IN to Riverdale, IL on the Indiana Harbor belt. They use mostly six-axle cars.

Ryan, thanks for that explanation. I've definitely seen those cars. I'll check out rrpicturearchives.net after 11pm while im at work to see them.

The "Acme Steel" cars on the IHB older bottle cars have ten axles 3 + 2 --2 + 3, while newer ones have twelve 3 + 3 ---3 + 3

Celanese Acetate uses CELX tankers to haul acid to Celco in Narrows, VA. I recently saw two of them in the NS yard at Radford, VA.

are these 3 axle trucks meant to rotate at all or be cushioned more? it looks like a second piece adapted onto teh trucks. they look so much more different then heavyweight coach trucks.

The three axle trucks are designed to spread the weight of a heavy load, over a wider area, reducing axle loadings, both for the rails, and for the axles themselves. There is a degree of "cushion" built into the trucks, via the primary springs, with inner and outer coil packs. The truck does articulate up and down, but it maintains a constant contact with the bolster, thus sharing the weight load somewhat evenly, while tracking tangent. They do swivel, being mounted in a standard type center cup, but have no special pivoting in a lateral plane. The pivot points support vertical articulation only. Hope this helps.

Some of the big Treadwell Bottle Cars ment for moveing molton steel were built with 3 axle trucks under them.
