4 extra wheels, 2 extra magnetic couplers, 6 extra magnets. Instruction manuals for the Locomotive, Caboose and the Green Passenger car.
I do not have a manual explaining how to put the track together. It is easy to find out the information on You Tube.
I will leave the Locomotive and cars together. I put the track together and the train ran like a champ. Will see if I can add a video to this later.
