About this Exam
Prepare with the Amtrak Maintenance Level 2 (AMT-2) Practice Test practice quiz. This question bank includes 10 questions covering electric, approach, function, located, and equipment. Use it to review important concepts, identify knowledge gaps, and build confidence for the related exam, course, or assessment.
Sample Questions
Question
1
What is the function of a Bus Jumper?
Explanation:
A bus jumper is a high‑voltage conductor that links the traction power buses between pantographs or between units in a consists, carrying the main current from one part of the electrical system to another. This allows multiple pantographs or cars to share the same power source and keeps power flowing when connecting different sections or units. It’s designed for the system’s voltage and current, and must be checked for proper insulation, wear, and secure connections. The pantograph insulating pad, a switch that disconnects the overhead line, and a monitoring device are different components with separate functions.
Question
2
Which term describes a device located on top of electric equipment that collects power from the contact wire by means of a collector head assembly?
Explanation:
Pantograph is the device mounted on the roof of electric locomotives or other electric equipment that collects power from the overhead contact wire. It uses a collector head assembly—often a carbon or metal shoe—that slides along the wire and maintains spring-loaded contact so current can flow into the traction system. This arrangement lets the train draw the electrical power it needs while maintaining a stable connection as speed and alignment change. Other components like a ground wire, impedance bond, or phase break serve different functions in the electrified system (grounding, signaling/return isolation, or phase separation) and do not collect power from the overhead wire.
Question
3
What is the minimum approach distance for AMT-2 qualified employees when walking over and around energized Third Rail?
Explanation:
Working near an energized third rail requires a precise clearance to prevent electric shock or arcing. The minimum approach distance is six inches, because this small air gap reduces the chance that an arc or incidental contact could occur if a worker’s body, tool, or equipment comes close to the live rail. The third rail carries high voltage traction power, and arcing can happen across surprisingly short gaps, especially under certain conditions like moisture or contamination on footwear or gear. Maintaining a six-inch clearance allows AMT-2 qualified employees to move over and around the rail safely while following established procedures for near-rail work. Distances like three feet, four feet, or fifteen feet would unnecessarily hinder operations and are not the required minimum.
Question
4
How must the Third Rail be considered?
Explanation:
The third rail is part of the traction power system and presents a high electrical hazard, so it must be treated as energized in normal operation. You only regard it as de-energized when you have confirmed isolation and have tested to verify there is no voltage present. When work is being done, a third rail warning device must be in place to alert others, and protection must be provided by a qualified Class a third rail employee. This combination balances safety with the need to perform maintenance, because it prevents accidental contact with live power while permitting authorized work under controlled conditions. The other approaches fail because they either assume it’s always off, rely on a simple switch without the full protective process, or allow work near a live third rail with no warnings, all of which would be unsafe.
Question
5
Where are Phase Break (PB) signs or Position Light (PB) indicators located?
Explanation:
Phase Break signs and their indicators are placed to give the train crew advance warning of an approaching electrical phase change. To achieve that warning effectively, the PB signs and Position Light indicators are mounted on the first catenary pole in advance of the PB sign. This setup ensures the operator in the cab can see the cue early enough to slow down, adjust power settings, or prepare for the change before reaching the actual phase break. Placing the indicators on a later pole would reduce the available reaction distance, and putting them on the ground or inside the cab would either degrade visibility or remove the external, forward-facing cue. So the first pole before the PB sign is the standard, reliable location.
