footer_05 4 Wheel Passenger Truck Project Update

We have received and reviewed the sample trucks from Boo Rim and now they are making the production run of trucks. The complete run has been reserved footer_05

 

 

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.

 

The 41-HR-11 features a 9-foot wheelbase, 6" x 11" roller bearings, clasp brakes and Houdaille rotary shock absorbers. As per Pat Wider's article, "Lightweight Passenger Car Trucks" in Railway Prototype Cyclopedia, Vol. 6, the 41-HR-11 was used by the following roads: AT&SF, B&0, C&NW, ERIE, ILLINOIS CENTRAL, ROCK ISLAND, MKT, MISSOURI PACIFIC, PULLMAN AND THE UNION PACIFIC.

 

This version of the 41-N-11 features an 8'-6" wheelbase, plain drop equalizer bar 6" x 11" Timken roller bearings, clasp brakes, Houdaille rotary shock absorber. Our truck will have Monroe Shock Absorbers. It was used by ACL, B&0, C&NW, CB&Q, D&RGW, ERIE, FEC, GN, ILLINOIS CENTRAL, L&N, L&W, NYC&StL, Pere Marquette, PRR, RF&P, SAL, SP&S, SOUTHERN, and WofA.

 

This version of the 41-N-11 features an 8'-6" wheelbase, I beam drop equalizer bar, Hyatt 6" x 11" roller bearings, clasp brakes, a Monroe shock absorber, and was used by C&O, ILLINOIS CENTRAL, N&W, PRR, SEABOARD, WABASH, and UP. There may be additional railroads that also used this type truck. Pat Wider's Railway Prototype Cyclopedia article "Lightweight Passenger Car Trucks" states that "trucks with I-Beam equalizers became the more popular truck beginning in 1948.

 

Other roads, notably the New York Central, Southern Pacific, Northern Pacific and Kansas City Southern, used 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 HERE to view.

 

If you would like a detailed listing of each road's passenger truck usage, click HERE to view Pat Wider's 5-page sleeper car listing.

 

If you would like to really learn more about the various 4-wheel, lightweight truck types produced during the late 30s through the 1950s, click HERE to read an excerpt from Pat Wider's article, "Lightweight Passenger Car Trucks." When reading Pat's article, you'll notice that there are several truck designs almost identical to the 41-HR-11 and 41-N-11. These include the 41-NO-11, 41-C-11, 41-CS-11, 41-CN-11 and the 41-CUS-11. They're difficult to tell apart. You be the judge.

 

Another valuable resource is the 15 volume set of "The Official Pullman-Standard Library."

 

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.
