O-31 OPERATION
While the RailKing SD-90 MAC diesel is more than capable of operating
on O-31 curves and switches, you may find that certain light freight cars are
prone to derailing when being pulled or pushed by the RailKing SD-90
MAC through O-31 switches. Should this occur, we suggest adding weight
to the cars making them heavier and less likely to derail. In addition, the 6-
wheel version may rub the switch box.
