ABTH 103.6.1

Once a train is moving, do not increase the throttle until:


  1. The air flow is below 20 CFM.
  2. The ETD indicates the brake pipe pressure is above 80 psi.
  3. Either the amperage or the tractive effort decreases.
  4. The accelerometer no longer indicates a speed increase.

Answer: Either the amperage or the tractive effort decreases.
Feedback:
It's important to monitor the amperage or tractive effort levels to determine when to advance the throttle. If you continue to increase your throttle before the load stabilizes and starts to decrease, the potential of creating high draft forces increases.
