With this Terminal track you can connect one power pack and two controllers.  You can use it on 2, 4, 6 or more lanes. Simply get one track segment for each two lanes of track. And of course you will need to have one power pack for each Terminal track.  The white deco positions dots on the lane controlled by the controller plugged into that particular terminal location.

You can also change direction simply by flipping the power plug. Too easy!

These pieces will be shipped loose bulk.
