L.E.T. Flashcards
After completing your trip, while entering defects into the LCDI system none of the choices describes the defect you encountered. What should you do?
Pick something close and add comments
Before starting the diesel engine you are required to check the fluids. What are you required to do with the fluids after the engine is started?
Recheck them Water Lube Oil ( dip stick mid engine near floor) Air compressor Govenor Oil ( if it has one )
What connects the locomotives so they are trainlined, or allows trailing units to follow what is done on the lead locomotive?
27 pin jumper cable (mu)
If you enter the cab of a trailing unit how would you expect the automatic and independent brakes to be setup?
Automatic- Handle Off Cut Out Pinned
Independent- Released Cut Out Pinned
When changing a locomotive from lead to trail, the final position of the independent brake handle would be where?
Independent- Released Cut Out Pinned
When preparing a locomotive for service you are required to inspect many areas and do certain tests. What test involves you, or another qualified employee observing the locomotive brake pistons?
Locomotive Brake Test
During the ground inspection, what are you visually looking for?
Jummper cable, Air Hoses, Hot, Cracked, Flat Wheels Brake Piston Travel, Shoe Wear, Rigging Clear, Pins Gas cap, Excessive Oil Leak, Air Tank Water Build Up Nothing Under 2 1/2 inches Above Rail
During the engine room inspection, What are you visually looking for? What fluids will you check?
Excessive Exhaust or Burn Water
Excessive Oil Leak Lube Oil
Anything Laying Around Air Compressor Oil
Govenor Oil If Has
How do you check deisel engine lube oil?
Dip-Stick, Usually Mid Engine, Near The Floor
During your trip you report a defect on your lead locomotive to the LCDI desk. When you enter into the LCDI system at the end of your trip you see that the locomotive you reported is showing “COMPLETED”. How should you handle this?
Check and make sure it was completed properly,
complete the rest of your consist.
Starting an EMD locomotive, which has the Engine Start Switch located in the engine room, you prime the engine 20 second, push the lay shaft 1/3 of it’s travel, and turn the statr switch to start. What does pushing the lay shaft do?
Sends Fuel To The Cylinders
After securing the locomotive, which is step one, there are six more steps to completing a locomotive brake test. What are they?
Release Brakes= Automatic if applied and Independent
Tests = Apply and Release
Apply Brakes = Make 20lb Reduction w/Automatic
Tests = Brake Pipe
Release Brakes= Bail
Tests = Actuating
Apply Brakes = Further Reduction Automatic (Full Ser)
Tests = Brake Pipe
Release Brakes= Release Automatic
Tests = Brake Pipe
Apply Brakes = Apply The Independent
Tests = Apply and Release
While inspecting your consist at a location where Mechanical forces are not available, you notice the rear locomotive has a slightly bent rail. What do you do?
Report it to LCDI (MOC) by radio or phone
Part of your job as a Locomotive Engineer is to insure that your locomotives have the proper inspection. How often do locomotives need to be inspected? Where do you record the inspection date and time?
Once Each Calendar Day The Locomotive Is In Use.
ME65
If you need to charge your train and want the air compressor to operate at maximum output what throttle notch would you use for an EMD with a shaft driven air compressor? What about a GE with a motor mounted air compressor?
EMD= Notch 3 or 4 GE = Notch 1
Air pressures are vital to the Engineer. How should the air gauges read before attempting to move locomotive?
a. Main Reservoir= 15 Higher than regulator valve setting
at least 105 for 90lb line
b. Equalizing = 75, 90, or 100 w/Automatic Released
c. Brake Pipe = Same as Equalizing Res.
d. Brake Cylinder= Whatever stenciled on the wall
w/ Independent applied
On trailing locomotive the Automatic Brake handle should be in Handle Off, but should you leave it cut in or cut out?
Automatic= Cut out in trail
Automatic always cut out unless it’s the leader
Out of the three trainline switches (Engine Run, Generator Field, & Control and Fuel Pump) on the control stand, which one(s) need to be up for the engine to start?
Control & Fuel Pump
The Engine Run, Generator Field, and Control & Fuel Pump switches should be up, or in the on position for a lead locomotive to operate. How should they be for a trailing unit?
Down/ Off/ Out
EMDs and GEs have different requirements about how long you can attempt to crank the deisel engine. How long should you attempt to crank an EMD with dual starting motors? Why? What do you do if the engine does not start in that amount of time?
EMD= 20 Seconds crank
Motors will over heat and may burn up
Wait 2 minutes if it doesn’t start for motors to cool
down look for any missed steps
If you were starting a GE Dash 8 or Dash 9, and it failed to start after 25 seconds what would you check?
DID Pannel for any faults
A completed ME-65 should have the date, time, place of inspection, and what else on it?
Signature
Each step of the locomotive brake test is used to test a specific air hose. Which step and action tests the Actuating Hose?
Bail off step 2
Some locomotives are equipped with governors that have a sight glass to visually determine the fluid level. How much oil should be visible before starting and after starting?
Before= Just Visible After = 1/2 Full
