Only one track call button is needed. Pushing it once turns off the power and pushing it a second time turns it back on. Most tracks have a hand held switch on an extension cord, that works best if there is a spare person to work the button. If the drivers have to use the track call button it is probably best to have a button for each driver's station, however there is a possible hitch with that arrangement. When there is a crash two drivers might hit their buttons at the same time, in that case the track call would be cancelled. If it was me I would add a fourth track call button on an extension cord, SCC sells those as well. Track calls can also be activated from the computer keyboard using the Enter key or spacebar, my experience with that is that in the heat of battle the wrong key may sometimes get pressed.
