OK Folks,
Here is a holiday physics quiz that might explain how real railroads
use slack action. If you have a two car train where the cars are identical,
the force between the two cars is half that of the locomotive pulling on the
first car. If you add a third car, the force between the second and the third
is one third of the force that the locomotive pulling in the first car. So how
many cars do you have to add before the cars are actually pushing on the
locomotive? ;~)
