Union Pacific GCOR Terms and Definitions || Solved Correctly.
Automatic Block Signal System correct answers A series of consecutive blocks governed by
block signals, cab signals, or both. The signals are activated by a train or by certain conditions
that affect the block use.
Absolute Block correct answers A length of track that no train is permitted to enter while the
track is occupied by another train
Absolute Signal correct answers A block or interlocking signal without a number plate or
designated by an A marker
Adjacent Track correct answers Parallel tracks that are not separated by a single lane roadway or
similar distance; only applies if Track Breach Protection is required
Articulated correct answers Permanently connected multiple unit cars that share a common truck
Automatic Train Control Actuator correct answers An ATC brake applying apparatus
Automatic Cab Signal System correct answers A system that allows cab signals and the cab
warning whistle to operate automatically
Automatic Train Control correct answers A system to enforce compliance with cabin signal
indications. If the train exceeds a predetermined speed for a given cab signal indication and
speed is not reduced at a sufficient rate, brakes are automatically applied.
Automatic Train Stop Systems correct answers A system activated by wayside inductors
positioned to apply the brakes automatically until the train stops
Block correct answers A length of track: between consecutive block signals, between a block
signal and the end of block system limits, or in automatic train control limits, the use of which is

Cab Red Zone correct answers Exists during critical times or when multiple tasks are occurring;
an environment must be created in the locomotive control compartment that focuses exclusively
on controlling the train, verbally communicating restrictions, and proper application of the rules
Cab Signal correct answers A signal in the engineers compartment or can that indicated a
condition affecting train movement. Cab signals are used with interlocking or block signals or
without block signals.
Cars correct answers Railroad cars
Centralized Taffic Control correct answers A block system that uses block signal indications to
authorize train movements
Clearance Point correct answers The location closest to a switch where it is safe for equipment,
and a person riding the side of equipment unless prohibited, to pass equipment on an adjacent
track. Clearance Point location may be identified by a clearance cone and/or painting of rails and
ties
