RAILKING
O-31 OPERATION
While the RailKing Doodlebug 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 Doodlebug
through O-31 switches. Should this occur, we suggest adding weight to the
cars making them heavier and less likely to derail.
