Welcome to the second part of this tutorial on driving CSX locomotives. This second part covers the AC4400CW. For information on driving the GP40-2, SD40-2 and GP38-2 see Part 1. Any questions about this tutorial or a suggestion for a future tutorial can be added in the comments section at the bottom of the page

Driving the LocomotiveEdit

20171208194532 1
This section of the tutorial covers driving the locomotive when it has already been started. This is how the locomotive starts in services and some scenarios.
Firstly, move the independent brake to the release position, the independent brake is the black handle on the far right of the image. Secondly move the automatic brake, the red handle to the left of the independent brake into the release position. The reverser is the small handle in the center of the image, move this into either the forward or reverse position. Then move the throttle, which is located between the reverser and the automatic brake into the notch 1 position. Your train should now start moving.
To stop the locomotive, move the throttle into the idle position and then apply the automatic brake. Be careful not to apply the automatic brake beyond the 'full service' position. The dynamic brake may also be used to slow the locomotive down.

Starting the LocomotiveEdit

First, set the isolator switch to start, then press the engine button to power the locomotive. Wait until the engine is fully running, you can check the start-up progress by looking at the monitor on the desk in front of you. Once ready, switch the Isolator to run and turn the Engine Run, Gen Field and Control switch on. From the monitor, select the Air Brake button on the IFD Keypad underneath the screen. From there, change the Cut-Out Value setting to Cut-In, make sure to save the settings before exiting back to the main screen. Wait for the brake pressure to be adjusted to the right amount before releasing the Independent Brake, releasing the Automatic Brake will speed up the pressure. And finally, release the handbrakes if it was applied before starting up this locomotive.

Multiple Unit WorkingEdit

The same rules and settings apply to the GE AC4400CW as for the EMD SD40-2 and EMD GP38-2 as shown in tutorial 1.

For the brake configuration, you should use the 1 key on the engineer’s IFD Keypad to select the Air Brake Setup screen and select the appropriate setup. Once complete, press the F6 key to save the changes.

The Engine Run, Gen Field, and Control switches perform the same tasks as on the EMD SD40-2 and must be set up following the same rules as the EMD SD40-2 on each locomotive in the consist.

Correct LightingEdit

The GE AC4400CW has slightly different controls to the EMD SD40-2 and EMD GP38-2, with a five-position switch on the wall behind the engineer’s seated position.

If this unit is a lead unit, then set it to either;

Short Hood Lead Edit

If the short hood of the locomotive is outward facing and should have its lights operated.

Long Hood Lead Edit

If the long hood of the locomotive is outward facing and should have its lights operated.

If this unit is trailing, then set it to either:

Short Hood Trail Edit

If the short hood of the locomotive is outward facing and should have its lights operated.

Long Hood Trail Edit

If the long hood of the locomotive is outward facing and should have its lights operated.

Otherwise, if the unit is on its own or in the middle of a consist, set it to Single or Middle unit.

In the EMD SD40-2 and EMD GP38-2 examples, if those locomotives were replaced with GE AC4400CWs then they would be defined as follows:

Lead Unit: Short Hood Lead

Trailing Unit #1: Single or Middle Unit

Trailing Unit #2: Short Hood Trail

Resetting PCS ApplicationEdit

When the Pneumatic Control Switch (or PCS) is open, the train brakes cannot be released and the throttle controls are deactivated. To operate your train again you must reset the PCS.

You can tell if it is activated by looking for the PCS OPEN indicator being present on the engineer’s IFD.

Once the train has come to a complete stop, follow these steps:

If there is an alarm such as the Alerter sounding, acknowledge it (Q Key, B button on the controller).

  1. Set the Throttle to Idle
  2. Set the Reverser to Neutral
  3. Set the Independent Brake to Full Service
  4. Set the Automatic Brake to Emergency
  5. Wait for 60 seconds
  6. Release the Automatic Brake and wait for the Equalising Reservoir / Brake Pipe to return to 90psi

Important Note: The Compressor on the AC4400CW is computer controlled and will activate automatically to maintain the pressure in the Main Reservoir, unlike on the older EMD SD40-2 and EMD GP38-2 locomotives.

Once the Equalising Reservoir and Brake Pipe needles have returned to 90psi, and the main reservoir has recharged to 140psi, put the throttle back to Idle.

You should now be able to release the Independent Brake, set the Reverser and apply Throttle.
