I had seen these advertised some years ago with the 'feature' of actually rotating 'bearing caps' on the ends of the wheels' axles and wondered if that feature would add significant friction and drag to any engine pulling freight cars with these trucks. I finally made a purchase on eBay of 4 pairs of these and when they arrived I was stunned by the authentic detailing and the absolutely low-friction and easy-rolling characteristics. The 33" diameter all-metal wheel sets are to the NMRA RP-25 standard and ride in what appears to be a VERY low friction plastic molding (Delrin?). The axles appear to be a matte-finish rigid black plastic to insulate the two rails and the details in the precision-molded sideframes is astoundingly realistic - did you know there is a 'third' spring between, and slightly behind, the clearly visible two outer springs? I plan to carefully mask the wheel treads and the narrow axle ends(where the 'bearing caps' will be press-fitted on (DO NOT glue them on!) and airbrush the trucks with a rusty, deep brown Floquil paint and after that dries apply a very dilute 'wash' of flat black paint over the three springs(in the grooves between the coils) which should make the springs appear to be fully 3-dimensional! These are superb trucks for any ACF 'Precision Design' 70-ton capacity boxcar from the early 1960s to present day and are a true 5 STAR product from an excellent eBay seller! atget26 (9-10-2016)Read full review

The only "complaint" is the tiny bearing caps. I find keeping them on the sprue (plastic mold thingy) and pressing them on firmly before cutting from sprue is easiest One can put the slightest amount of super glue on the tops prior to pressing the bearings on, but don't get any on the truck or the brakes will be locked on.

Great detail, easy to assemble and a nice addition to most HO scale railroad cars.

Very realistic model of the prototype trucks.

Takes HO scale realism to the next level for those who appreciate fine precision detail in their model railroad layout.
