Helium Car Trucks (Bogies)?
Author: RRBaron

I wish to up-grade an old AHM plastic helium car as used by US Navy, Bureau of Mines and AEC. Does any TOs know what trucks to use? They were 100 Ton trucks I recall with outside clasp brakes. Does any HO supplier make these trucks or similar ones? What were they called? Thanks in advance!

The photo shows standard 100 ton rb trucks which were an upgrade to some of the cars. It has 2 brake shoes per axle on the inside. The original 100 ton brass bearing trucks had clasp brakes had 4 brake shoes on each axle, 2 inside and 2 outside.

Models of those trucks show up on the auction site though I believe they are called tank car trucks.

Here is a link to a 3 part article from an SP modeler about upgrading the ahm car. There is another series from an ATSF builder as well.

Good luck. I finally got an ahm car a couple of months ago.

Thanks for the picture! Where was this shot? However, this is the modern-day 100-ton roller bearing truck that was used. I am looking for the original trucks used on these cars from the 1940-1950s that had outside brake hangers and who makes / made them in HO? Thanks beforehand!

I used the Model Die Casting (now Athearn) SP iron ore car trucks on my helium car.

If you poke around on the Internet (modelingthesp.blogspot.com) you'l find an informative multi-part  history of all of the helium cars that addresses the various trucks used.

I think it was shot at the Amarillo Railroad Museum.

Indeed I got it to guide me in converting an AHM car--cheaply. Then I will auction said brass car on eBay.

The other posted pic of the Helium car trucks were after their last modification when they lost their outside clasp brakes.  Here is a shot of the trucks with the clasp brakes.  These are obviously roller bearings, however the older cars had the same basic truck with solid friction bearings.  I did a detailed article that was published in the Santa Fe Historical Society's mag THE WARBONNET on rebuilding the AHM cars into something reasonably decent.   I the article I show how I modified a set of the Roundhouse ore gon trucks as the clasp brake trucks.  In the detail of the model trucks is after I added the solid bearing boxes salvaged off a sacrificial set of friction passenger trucks and you can see how I build the outside brake beams. 

Hope this helps
