Air Brakes and Train Handling Rules - Alaska Railroad

64 Train Handling64.2.1 Slowing or Controlling Train SpeedFollow these train handling requirements when slowing or controllinga train:1. When using the stretch braking method and the desired speedhas been reached, reduce the throttle until train brakes are fullyreleased.2. When using dynamic and air brakes and the desired speed hasbeen reached, maintain enough dynamic brake to control slackuntil the train brakes are fully released.3. When operating in curved territory, keep the total braking effortfrom dynamic brakes, automatic air brakes, and independentbrakes at the lowest practical level.64.3 Train BrakingEnsure compliance with Rule 64.1, General Requirements For TrainHandling, by using proper train braking.64.3.1 Automatic BrakeUse the automatic brake as follows:A. Applying or Reapplying BrakesWhen applying or reapplying brakes, make brake pipe reductionsaccording to these guidelines:1. Make an initial brake pipe reduction as follows:a. For a fully charged system, reduce the brake pipe at least5 psi.b. For an uncharged system, reduce the brake pipe 5 psi belowthe previous reduction.2. Limit brake pipe reductions as follows:a. For light to heavy grade territory, limit the effective brakepipe reduction to 15 psi or less.64-2 ARRC Air Brakes and Train Handling Manual June 1, 1996
