HO Dalman Trucks w/Lateral-Motion Detail w/RP-25 wheelsets (two trucks)

Dalman 2 Level trucks could also be equipped with the Barber Lateral Motion Device. This feature used steel rollers and a roller seat between the springs and bolster to provide a little side-to-side movement of the car body to the track, reducing wear to wheel flanges, journals and couplers. Railroads using these trucks included ATSF, CN, CP, CNJ, CB&Q, CNW, IC, MP (and subsidiaries I-GN and StLB&M), NP, RI, and SP.
