Announcing 4 Wheel Lightweight Passenger Trucks
River Raisin Models and our long time builder, Boo Rim Precision, are producing the 41-HR-11 truck and two versions of the 41-N-11 truck, one with a plain drop equalizer bar, and the other with an I beam drop equalizer. The 41-HR-11 was used under more Pullman-Standard, Budd and ACF-built lightweight passenger cars than any other 4-wheel truck during and immediately following WWII. The 41-N-11 was the most popular post-war 4-wheel truck.

Other roads, notably theused the earlier and nearly identical, 41-HR or the 41-N truck, which used slightly smaller 5 1/2" x 10" roller bearings. The 41-HR and 41-N trucks are indistinguishable from the versions that we are building.
Some years ago, Mainline Modeler published a one-page truck chart showing which railroads used which trucks. Click to view.

Finally, if your looking to put some well detailed, sprung, equalized trucks under your American Models lightweight passenger cars, the correct replacement truck is the 41-N-11.
These trucks will be constructed in brass with stainless steel wheelsets and will be fully sprung, fully equalized, with a swing hanger mechanism. Available in black, silver or unpainted. The 41-N-11 will also be available in Enchantment Blue for the C&O and Pere Marquette.
