PROTO COUPLER WIRE CONNECTION
If you are operating your RailKing F-3 B Unit with the MTH RailKing F-3
AA set see figure 2 for connecting the Proto-Coupler wire harness. If you are
operrating your RailKing F-3 B Unit with a non Proto-Sound® engine, you
might want to remove the shell as shown in figure 1 and place the
Proto-Coupler wire harness into the shell so that the wire will not cause any
operational problems.

O-27 OPERATION
While the F-3 B Unit diesel is more than capable of operating on O-27
curves and switches, you may find that certain light freight cars are prone to
derailing when being pulled or pushed by the RailKing F-3 B Unit through
O-27 switches. Should this occur, we suggest adding weight to the cars
making them heavier and less likely to derail.
