Sample Assistant Diesel Locomotive Driver Qualification Attestation Practice Questions
Try these sample questions to review concepts for the Assistant Diesel Locomotive Driver Qualification Attestation exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 96+ question experience with AI tutoring.
1What is the primary regulatory purpose of the Locomotive Technical Condition Book (Form ТУ-152) during the acceptance and turnover of a diesel locomotive?
A.To record discovered mechanical and electrical defects, completed inspections, fluid additions, and turnover crew signatures
B.To serve as a commercial freight invoice listing cargo weights and destination customs codes
C.To log only the personal vacation and overtime hours of the locomotive brigade members
D.To provide dispatchers with a permanent telegraphic record of track switch alignments
Explanation: Form ТУ-152 is the official logbook kept in the locomotive cab where crews record equipment defects, maintenance work performed, oil and coolant replenishments, and official acceptance and turnover signatures. Reviewing and signing Form ТУ-152 is mandatory under Ukrainian railway operating rules before operating the locomotive.
2Which check of electrical protective equipment is appropriate during diesel-locomotive acceptance?
A.Check that ordinary work gloves and leather boots are dry; dielectric equipment is unnecessary below the locomotive's traction voltage
B.Check the required dielectric gloves for damage and a valid test date, and inspect insulating mats for cleanliness and damage
C.Check only the insulating mat's electrical-test stamp; ordinary gloves can then replace dielectric gloves
D.Check only insulated hand tools; gloves and mats are unnecessary when the equipment enclosure is grounded
Explanation: The crew checks that the required electrical protective equipment is present and serviceable. Dielectric gloves require a valid test stamp; insulating mats are inspected for damage and contamination rather than subjected to periodic electrical testing in service. Protective equipment does not replace the required isolation procedures.
3Which safety and signaling inventory must the assistant driver confirm is on board the diesel locomotive during acceptance?
A.Track tamping picks, ballast gravel bags, and rail alignment hydraulic jacks
B.Commercial cargo balance scales and parcel wrapping tape
C.Standard brake shoe chocks (гальмівні башмаки), red and yellow signal flags, a signal lantern, and acoustic petards
D.Overhead contact wire splicing sleeves and pantograph carbon strips
Explanation: During acceptance, the crew checks the required safety and signaling inventory: brake shoe chocks (гальмівні башмаки) for securing rolling stock, red and yellow hand signal flags, a serviceable signal lantern, and acoustic warning petards. Presence alone is insufficient; the equipment must be fit for use.
4When inspecting the diesel engine crankcase before starting, what should the oil level show on the calibrated dipstick (масломірний щуп)?
A.Above the upper mark, to provide a reserve for the entire shift
B.Below the lower mark, because the pre-lubrication pump will supply the missing oil
C.At any visible mark, provided the oil-pressure gauge showed a normal reading on the previous run
D.Between the upper and lower calibrated marks with the locomotive parked on level track
Explanation: Before starting a diesel locomotive engine, the oil level must be checked on level track using the crankcase dipstick. The level must lie strictly between the minimum and maximum calibrated marks to prevent both oil starvation (if too low) and hydrodynamic foaming, crankshaft drag, or oil ingestion (if overfilled).
5Where does the assistant driver check the cooling water level during the pre-trip engine room inspection of a diesel locomotive?
A.At the water level gauge glass (водомірне скло) on the cooling system expansion tank
B.At the diesel engine's lubricating-oil dipstick
C.At the fuel-tank level gauge
D.At the air compressor crankcase sight glass
Explanation: The expansion tank (розширювальний бак) provides the cooling-system level indication. Where a water-level gauge glass (водомірне скло) is fitted, read it and check the level against the locomotive's specified operating marks before starting the diesel.
6What is the primary visual check for hand-held fire extinguishers (powder and carbon dioxide) during locomotive acceptance?
A.A current service label only; damage to the locking device can be assessed after departure
B.Current service status, intact seal and locking device, legible marking, an undamaged horn or hose, and normal pressure indication where a gauge is fitted
C.A normal gauge reading only; the hose and safety pin do not affect readiness
D.An intact discharge horn only; charge and service status can be checked after the first use
Explanation: Check the extinguisher's service status, marking, seal, locking device, and horn or hose. Where a pressure indicator is fitted, its reading must be in the specified operating range. Do not expect every CO2 extinguisher to have a pressure gauge; follow its prescribed charge-check and servicing procedure.
7How should the assistant driver assess the operating condition and temperature of locomotive axleboxes (букси) immediately after a run or during crew changeover?
A.Check only wheel-tread temperature, because it reliably gives the temperature of the axlebox bearing
B.Look only for grease leakage; if none is visible, assume the bearing temperature is normal
C.By feeling the front and rear covers of each axlebox with the back of the hand or using an infrared pyrometer to detect abnormal overheating compared to adjacent axles
D.Use the outside air temperature as the axlebox temperature without checking the housings
Explanation: During turnaround and intermediate stops, the crew inspects roller bearing axleboxes (букси) by carefully checking the temperature of the housing and front cover (using an infrared pyrometer or back of the hand) and looking for grease leakage, loose bolts, or discoloration. Excessive heating relative to ambient temperature or adjacent axles indicates bearing distress.
8Under Ukrainian Rules of Technical Operation (ПТЕ), what is the allowable range for the height of the automatic coupler (автозчеп СА-3) centerline above the top of the rail head on a diesel locomotive?
A.950 mm to 1080 mm
B.980 mm to 1100 mm
C.950 mm to 1100 mm
D.980 mm to 1080 mm
Explanation: For a locomotive, the PTE coupler-centerline limits are at least 980 mm and at most 1080 mm above the rail head. Apply the limits for the vehicle named in the question; the minimum for a loaded freight wagon is different.
9Which statement correctly describes the required safety protection for a diesel locomotive's high-voltage chamber (ВВК)?
A.The chamber's door interlocks and guards must remain effective, and personnel must not enter while the diesel-generator is running
B.A warning placard alone is sufficient if an authorized crew member supervises access
C.An ordinary door catch can replace the protective interlocks if it holds the panel closed
D.Opening the battery isolator permits entry even while the diesel-generator continues to run
Explanation: The chamber's protective interlocks and guards must be intact and must not be bypassed. Ukrainian locomotive safety rules prohibit entering a diesel locomotive's high-voltage chamber while the diesel-generator is running. Follow the prescribed isolation procedure before access.
10What is the correct sequence when energizing a cold, parked diesel locomotive from its storage battery?
A.Leave the lighting and auxiliary loads switched on, then close the battery switch without checking readiness
B.Check readiness with loads off, close the battery switch (рубильник АБ), verify the specified battery voltage, then enable the required control and lighting circuits
C.Close the battery switch and begin the starting sequence; check battery voltage only after a failed start
D.Use the previous crew's voltage reading and enable all auxiliary loads before checking the present battery condition
Explanation: Follow the locomotive's preparation procedure: confirm readiness with unnecessary loads off, connect the storage battery, and check its voltage before enabling the required circuits. Starting-voltage requirements depend on the installed battery and starting system; use the specified value for that locomotive.
