SP design 40-ton caboose truck

The Vulcan design freight truck was designed and patented by George Floyd on May 3, 1910, resulting in the foundation of ASF (American Steel Foundries) in the early 1920’s, based on the Vulcan side frame.  It eventually evolved into a single casting.

The Southern Pacific adopted this truck for it’s caboose fleet in the early 1920’s and was used under hundreds of C-30 caboose in both the West and East Divisions into the 1950’s.

This fully assembled, all-brass model by Boo Rim Precision of Korea, follow’s ASF’s plans and features ball bearings, working journal covers, full brake detail, fully equalized construction with working leaf springs, tapered stainless steel axles, and sintered (70% iron and 30% stainless steel) rib-back wheels with accurate AAR profile.  Treads polish to a realistic running appearance.
