That track is not going to work for 9V. The rails on the 9V electric system have metal stripes that conduct electricity and send it to the motor. The rails you have are from the 12v/4.5v system from the 1980's. The 12v rails have one center rail that is used by the motor to take electricity and run.
12v/4.5v system
The 9V rail (shown above) has little holes for the conector, and does not have a center rail, instead it uses metal stripes on the rails.
