A single 9 volt battery may drain too quickly, Try to wire 3 of them in parallel + to +, - to - then to the track . That will give you more amperage with the same voltage. Do not wire them + to -then to the track that will increase the voltage above 12 volts.
I almost forgot about speed control and direction. There you will need a double pole double through switch and a potememator or rheostat wired in between the batteries and track.
