B. the train weighs less than 6250 ton.
C. Under any circumstances.
C. Under any circumstances.
Engineers are responsible for ensuring all locomotives in their charge are inspected each calendar day the locomotive is used. If the controlling locomotive has a current ME-65, is a Calendar Day Inspection required on the trailing locomotives?
A. No. A current ME-65 on the controlling locomotive indicates a current Calendar Day Inspection on all locomotives, including DP power.
B. Yes.
A. No. A current ME-65 on the controlling locomotive indicates a current Calendar Day Inspection on all locomotives, including DP power.

A. 1 and 1/3 conventional (non-high adhesion) axles.
B. 1 and 2/3 conventional (non-high adhesion) axles.
C. 1 and 1/2 conventional (non-high adhesion) axles.
A. 1 and 1/3 conventional (non-high adhesion) axles.
To avoid extensive traction motor damage, under no circumstances should diesel locomotives pass through water, which is deeper than 2 inches above the top of the rail. When passing through water less than ____ inches above the top of rail; speed must not exceed ____ to ____ MPH.
A. 3 inches above the top of rail; speed must not exceed 1 to 2 MPH
B. 2 inches above the top of rail; speed must not exceed 1 to 2 MPH
C. 2 inches above the top of rail; speed must not exceed 2 to 3 MPH
D. 3 inches above the top of rail; speed must not exceed 2 to 3 MPH
C. 2 inches above the top of rail; speed must not exceed 2 to 3 MPH
A freight train in dynamic braking is entering a 25 MPH turnout at a speed of 24 MPH. The locomotive consist is made up of three six-axle locomotives, all of which are equipped with EXTENDED RANGE dynamic brake. Until the lead half of the train is through the turnout, the dynamic braking force must not be permitted to exceed: A. 200 amps. B. 400 amps. C. 600 amps. D. 750 amps.
B. 400 amps.
Engineers will check the operational status of the dynamic brake on the locomotive(s) they are called to operate by:
A. Reviewing the completed Form ME-112 that has been left in the cab of the controlling locomotive.
B. Completing a new Form ME-112 indicating the status of the dynamic brake of each unit in the controlling consist before going off duty. NOTE: Any locomotive checked “Inoperative” must also be tagged with Form ME-109.
C. Leaving the form in the cab of the controlling locomotive of the consist and discarding any previously completed forms.
D. Complying with instructions in (a), (b) and (c).
D. Complying with instructions in (a), (b) and (c).
An Engineer is at the throttle of the lead locomotive of a 3 unit consist in control of a freight train that has been operating at the maximum authorized speed of 50 MPH. Due to a consistently flashing wheel slip light, indicating the possibility of a locked wheel or slipped pinion gear, the Engineer has reduced the throttle in an attempt to get the light to go out. The light has remained illuminated. Therefore, the Engineer must:
A. Immediately stop.
B. Perform a roll-by inspection to ensure all axles in the locomotive consist are turning freely.
C. Both (a) and (b).
C. Both (a) and (b).
When examination of the Form ME-65 indicates the required calendar day inspection is not in date for a locomotive and there are no mechanical forces assigned to perform the inspection, Engineers will:
A. Inspect the locomotive.
B. Report defects to the LCDI desk (if mechanical forces are not on duty locally).
C. Note the time and location of the inspection in the appropriate line for the current date on the Form ME-65 in the operating cab of each locomotive in the consist.
D. Comply with all items above.
D. Comply with all items above.
A running release must not be made on any freight train following a penalty application of the train air brakes. Following penalty brake application, freight trains must come to a complete stop before train air brake is released.
A. True
B. False
A. True
A locomotive that develops a non-complying condition en route may continue to utilize its propelling motors, if it is safe to move the locomotive, until:
A. The next calendar day inspection.
B. The nearest forward point where repairs necessary to bring the locomotive into compliance can be made.
C. The earlier of A or B.
D. It is safely possible to shut down the locomotive and continue dead in tow to the nearest point where repairs can be made.
C. The earlier of A or B.
Except where authorized by Special Instructions, no more than the equivalent of \_\_\_\_\_ conventional powered axles may be used in pusher service. A. 8 B. 12 C. 16 D. 24
C. 16
The independent brake may be used only in:
A. Switching or handling a light locomotive
B. Starting a train on descending grade
C. In an emergency
D. All of the above
D. All of the above
When performing a brake pipe leakage test, the initial brake pipe reduction to be made is: A. 10 PSI. B. 15 PSI. C. 20 PSI. D. 25 PSI.
C. 20 PSI.
