  • Running with 90 psi brake pipe pressure.  You make a 10 psi reduction, brake pipe is now 80 psi.  For some reason the brakes on the train start to release, you need to increase the reduction by another 5 psi, brake pipe now 75 psi. 

    A similar scenario, instead of the brakes releasing on their own you release them from a 10 psi reduction .  Train line climbing from 80 psi back towards 90 psi.  Before the system is fully recharged, you need to reapply the brakes.  In this instance you would need to make a 15 psi reduction.  

    Both cases are to ensure that brakes apply throughout the train.
