lowering Atlas car with 50-ton Bettendorf trucks
Atlas offers their 40' boxcars (single sheathed, double sheathed, rebuilt) with Andrews or Bettendorf trucks. The cars with Andrews trucks ride lower than those with Bettendorf (50-ton friction bearing). The truck mounting pad under the cars has a small cone on which the trucks ride. Bettendorf trucks can be drilled so the slid over this cone, after this the cars have the same riding height as those with Andrews.
