AMT 2 MAIN EXAM 2025/2026 QUESTIONS WITH
ANSWERS GRADED A+
✔✔Electric equipment used by commuter RR in local passenger service. Most units
have a pantograph on each car. There are some units called married pairs that have
one pantograph for two units. - ✔✔Multiple Units (MU)
✔✔A system of wires suspended between poles and bridges supporting overhead
wires. - ✔✔Overhead contact system
✔✔A device located on top of electric equipment which collects electric power from the
contact wire by means of a collector head assembly - ✔✔Pantograph
✔✔A location in the catenary to provide an isolated section between different sources of
power - ✔✔Phase Break (PB)
✔✔A document that acknowledges that a section of the catenary or third rail may be de-
energized. It graphically communicates this fact to all involved parties that electric trains
or electrical equipment are prevented from entering into the de-energized area. -
✔✔Plate Order
✔✔An employee in charge of power distribution. He manages the operation and
sectionalizing of Electric Traction power distribution, signal power, and 3rd rail systems
within their assigned territory. - ✔✔Power director
✔✔This designation is used throughout these instructions to indicate either the power
director of the train dispatcher. Either position may represent the correct employee to
contact in different situations. - ✔✔Power Director/Train Dispatcher
✔✔A diagram which indicates the area in which there are to be no electric train or
electric equipment moving. - ✔✔Power Sectionalizing Plate
✔✔The combination of rails, jumpers, impedance bonds, and cables that provide an
electrical return path from the train to the substation. - ✔✔Rail Return
✔✔A location designed to provide a separation of circuits while allowing for a
continuous collection power from the catenary. - ✔✔Section Break
✔✔Apparatus which is used to isolate or connect sections of the catenary, signal power,
or 3rd rail - ✔✔Sectionalizing Switch
✔✔The wire normally located on top of pole which protects conductors lighting by
providing a low resistance path to the ground - ✔✔Static Wire
