FUEL CONSERVATION - SHUTTING DOWN LOCOMOTIVES Due to the cost of fuel and the need to conserve this resource, locomotives MUST be shut down in accordance with the following fuel conservation methods at all times.

• Place the reverser in the CENTER position anytime the locomotive is stationary.

• To the extent possible, avoid using the stretch breaking method of speed control.

• Avoid having more locomotives on-line than those required to maintain the maximum speed permitted. Isolating from the rear of the consist forward; never isolate the controlling locomotive.

• Empty coal train movements will use only the locomotives necessary to move the train. Trailing locomotives will be isolated and when weather permits, SHUT DOWN.

• When handling lite locomotive movements, use only the lead locomotive for power. Trailing locomotives will be isolated and when weather permits, SHUT DOWN.

• Unless instructed otherwise by the train dispatcher, yardmaster, SHUT DOWN the diesel

engine in locomotives when: -The locomotive will not be used for sixty (60) minutes or more, and -Ambient temperature is above forty (40) degrees Fahrenheit.

Engineers must ask the train dispatcher, yardmaster, or work train employee-in- charge to determine the anticipated length of time the locomotive will not be used.

If necessary to do so, you may allow one diesel engine to idle in order to maintain an air supply to the train.

The following instructions apply regardless of the temperature:

[1] When a locomotive is equipped with the Automatic Engine Start Stop (AESS), this does not apply unless the AESS is known to be inoperable. Unless properly authorized, the turning off of AESS systems is prohibited.

[2] When taking locomotives in a consist off line, the lead locomotive will remain on line unless mechanical difficulties require otherwise.

[3] When a train or locomotives are stopped, the Engineer must center the reverser handle to activate the low idle feature and allow the Automatic Engine Start Stop (AESS) system to operate on units so equipped.

[4] When locomotives are set out on the line-of-road, shut down or isolated, the Engineer must notify the Train Dispatcher.

[5] When locomotives are shut down and moving in a consist, it will NOT be necessary to open the battery knife switch.

[6] Prior to any locomotive being shut down, it must idle for 10 minutes for temperature stabilization. Except in an emergency, never shut down a locomotive immediately after loading as this may result in engine damage. When locomotives are shut down, the main battery knife switch must be opened.

When shutting down locomotives you must also comply with NORAC Rule 108 and IHB-1 Rule L-237 and/or L-238.

When starting locomotives after being shutdown you must comply with IHB-1 Rule L-227 as found in the Summary Bulletin Order No. S-12

EXCEPTIONS: Power should be left running when:

1) Power is maintaining air brake pressure on a train (trailing units can be shut down as long as the lead unit remains running to maintain pressure) 2) Power has some known defect, such as faulty batteries, etc. which would prevent the power from being restarted.
