Railcar Maintenance Fundamentals
1. What is the primary purpose of preventive maintenance on a
transit railcar?
A. Increase passenger capacity
B. Reduce scheduled service
C. Prevent failures and maintain safe, reliable operation
D. Eliminate all component replacement
Preventive maintenance identifies wear and developing problems
before they cause failures, helping maintain safety, reliability, and
availability.
2. Before beginning maintenance on a railcar, what should a
technician do first?
A. Remove the carbody panels
B. Start troubleshooting immediately
C. Review applicable procedures and establish the required safety
controls
D. Disconnect the batteries without documentation
Maintenance must begin with proper procedures, hazard
identification, and required safety controls.
,3. What document normally provides the manufacturer's approved
maintenance procedures for a railcar component?
A. Passenger timetable
B. Employee roster
C. Maintenance manual or technical documentation
D. Fare schedule
Technical manuals provide approved inspection, adjustment, repair,
and replacement procedures.
4. What is a component's service life?
A. The time required to install it
B. The period during which it is expected to perform acceptably
under specified conditions
C. The time required to inspect it
D. The time a railcar remains in storage
Service life represents the expected useful operating period under
defined conditions.
5. Why should maintenance personnel follow torque specifications?
A. To make bolts easier to remove
B. To eliminate inspections
C. To ensure fasteners provide the required clamping force without
being damaged
D. To increase electrical resistance
Correct torque produces the intended clamping force while reducing
the risks of loose or overstressed fasteners.
6. What is the best general practice when replacing a critical safety
component?
A. Install any visually similar component
B. Modify the component if necessary
C. Use the specified approved component and installation
,procedure
D. Reuse damaged mounting hardware
Safety-critical components must meet specified design and
installation requirements.
7. What does condition-based maintenance primarily rely upon?
A. Fixed calendar dates only
B. Passenger complaints only
C. Measured or observed equipment condition
D. Random component replacement
Condition-based maintenance uses inspection data, measurements,
diagnostics, and other indicators of equipment condition.
8. What is a maintenance defect?
A. A completed inspection
B. A condition that prevents equipment from meeting required
performance or safety standards
C. A normal operating characteristic
D. A maintenance schedule
A defect is an abnormal condition requiring evaluation, correction,
monitoring, or other action.
9. Why should maintenance records be completed accurately?
A. Only for payroll purposes
B. To increase train speed
C. To provide traceability of inspections, repairs, parts, and
equipment condition
D. To eliminate future inspections
Accurate records support safety, regulatory compliance,
troubleshooting, warranty tracking, and maintenance planning.
10. What is the purpose of a maintenance inspection checklist?
, A. Replace technical manuals
B. Provide a consistent method for verifying required inspection
items
C. Eliminate technician judgment
D. Increase passenger fares
Checklists help ensure required inspection points are not overlooked.
Section 2: Workplace Safety and Lockout/Tagout
11. What is the primary purpose of lockout/tagout?
A. Increase equipment voltage
B. Prevent unexpected energization or release of hazardous energy
C. Improve train acceleration
D. Reduce documentation
Lockout/tagout protects workers by controlling hazardous energy
before maintenance begins.
12. Which condition should exist before a technician works on an
isolated electrical circuit?
A. The circuit should be assumed dead
B. The absence of voltage should be verified using an appropriate
test instrument
C. The circuit should be energized
D. The circuit breaker should remain closed
De-energization must be verified because equipment can remain
energized through unexpected sources.
13. Why is stored mechanical energy hazardous?
A. It always increases electrical voltage
B. It can cause unexpected movement or release of force
C. It prevents corrosion
D. It improves lubrication
