Reduce the independent brake.3. Release the automatic brake.4. As the brakes release toward the rear of the train, advance thethrottle to RUN 2 or higher to start the train moving.5. Slowly reduce the independent brake until it is fully released.6. After the train starts to move, check to see if the amperage ortractive effort levels are decreasing.7. If these levels are decreasing, you may advance the throttle to thenext highest position.8. Observe the load meter and limit the throttle position if necessaryto avoid high draft forces.NOTE: If the train will not start, consider doubling. Applyingpower on a standing locomotive longer than necessary willdamage DC traction motors.CAUTION: Taking slack is not a recommended method forstarting a heavy train on a heavy grade.
