Brake commands from the LEAD Locomotive. The Locomotive Computer
changes Diesel Engine speed in response to certain operating conditions,
such as low Main Reservoir pressure, causes PCS OPEN by Air Brake
Computer or Hot Engine-extended time and TH limit to 6 notch. In these
circumstances, Diesel Engine speed is not precisely related to throttle setting.
10.5 Precautions Before Moving Locomotive
Before attempting to move the Locomotive under its own power, carefully
follow these precautions:
1. Make sure that main Reservoir Air pressure is normal.
2. Make sure that the Brake system is set up as LEAD on a single or
lead Locomotive and TRAIL on trailing Locomotive.
3. Check for proper Air Brakes application and release. Observe Brake
cylinder and Brake rigging.
4. Release Hand Brake and remove any wheel blocking.
10.6 Handling Light Locomotive
After starting the Engine, placing the Locomotive on line and completing the
preceding inspections and precautions, the Locomotive is handled as follows:
1. Set the ENG. RUN and GEN. FIELD switches "ON" on Control &
operating switch panel.
2. Set the Air Brake system on single or leading Unit for LEAD position.
3. Insert the Reverser Handle (Direction Handle) and set in the direction
of travel, Forward or Reverse. (Engine speed increases from low Idle
to Throttle 1 speed, as soon as the Reverser handle is thrown)
4. Release the Air Brakes.
5. Advance the Throttle handle as needed to move Locomotive at
desired speed.
6. Switch Headlights and other lights ON as needed.
Engine water temperature should be 49ºC or high before full
load is applied to Engine.

Locomotive response to Throttle movements is almost
immediate. There is little delay in power build up. Do not
operate Reverser Handle, Reverse to Forward or Forward to
Reverse when the Locomotive is moving.
