50 TON DALMAN TWO LEVEL TRUCKS WITH LATERAL MOTION
These have insulated metal RP-25 contour wheelsets.
Dalman 2 Level trunks 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.
