MTA Conductor Study Guide
ABSOLUTE BLOCK - ANS-a block hooked up between block limit alerts or managed indicators
in which no teach is allowed to enter whilst it's far occupied by way of every other educate or
equipment.
Absolute Block Signal - ANS-Proceed at: Slow Speed within interlocking limits; Maximum
Authorized Speed (MAS) now not exceeding 59 MPH out of doors of interlocking limits,
technique the next interlocking signal organized to prevent.
ALERTER - ANS-a tool, which detects the frequency of the engineer's moves and initiates a
penalty brake utility while the desired frequency of such movement isn't maintained or
recounted.
Approach Block Limit - ANS-If authorized to occupy subsequent block, continue. If not
authorized to go into next block, proceed organized to stop at next Block Limit signal. Trains
exceeding Medium Speed need to immediately reduce to that speed.
Approach Restricting - ANS-Proceed, organized to forestall at the subsequent sign. Trains
exceeding Medium Speed have to at once reduce to that pace. Note: Does now not convey
block or track information.
Approach Sign - ANS-Proceed prepared to forestall on the Working Limits Stop Sign; trains
exceeding Medium Speed need to right now start discount to that pace.
ASPECT DISPLAY UNIT (ADU) - ANS-the device in the controlling cab on which cab sign
components are proven.
AUTOMATIC TRAIN CONTROL (ATC) - ANS-a system that initiates a penalty brake application
if the engineer fails to reduce pace in compliance with cab signal symptoms.
AUTOMATIC TRAIN STOP (ATS) - ANS-a device that initiates a penalty brake utility if the
engineer fails to renowned a more restrictive cab signal indication.
BLOCK - ANS-a period of tune of defined limits, using which is governed by block restriction
signals, cab alerts, or Form M.
BLOCK LIMIT - ANS-a place wherein a block restrict signal is displayed.
Block Limit - ANS-Do now not bypass until authorized to accomplish that. For Temporary Block
Limits, the station name can be unnoticed.
, BLOCK LIMIT SIGNAL - ANS-a fixed signal indicating the restriction of a block below Manual
Block System (MBS) guidelines.
BLOCKING DEVICE REMOVED (BDR) CODE - ANS-a computer generated, specific, random
number transmitted from the Operations Control Center (OCC) to a Roadway Worker-in-Charge
(RWIC) earlier than fouling a song or beginning paintings in which CTC or Interlocking Rules
practice.
BULLETIN ORDER (BO) - ANS-order issued through authority of the Senior Vice President -
Operations that incorporates temporary items affecting the movement of trains. Bulletin Orders
continue to be in effect until fulfilled or cancelled.
CAB SIGNAL - ANS-a sign positioned in the engine manage compartment indicating a
permissible pace.
CENTRALIZED TRAFFIC CONTROL (CTC) - ANS-a technique of operation, on tracks unique in
the Special Instructions, where moves are authorized and ruled with the aid of interlocking
signals, cab indicators, commands issued with the aid of the RTC, or a aggregate of the above.
CLEARANCE POINT - ANS-the vicinity close to a turnout past which it is risky for passage on
an adjacent music.
CONTROL CONSOLE - ANS-the equipment by which the RTC controls switches, indicators,
and path of visitors in CTC territory, and which shows tune repute and occupancy.
CONTROLLED BLOCK - ANS-the block, or collection of consecutive blocks, between
successive managed signals in Centralized Traffic Control (CTC) territory.
CONTROLLED POINT (CP) - ANS-a station wherein alerts are remotely managed from the
Operations Control Center (OCC).
CONTROLLED SIGNAL - ANS-a set sign able to showing a Stop indication that is controlled by
means of the Rail Traffic Controller (RTC).
CONTROLLED TRACK - ANS-a tune below the control of an RTC.
DAILY TRAIN OPERATIONS BULLETIN ORDER (DTOBO) - ANS-order issued by authority of
the Senior Vice President - Operations containing Working Limits Stop Sign locations (Rule 22-
A), temporary velocity restrictions, bridge moves, and different safety critical commands and
facts.
DEADHEAD TRAIN - ANS-a passenger train on which no revenue passengers are carried.

in which no teach is allowed to enter whilst it's far occupied by way of every other educate or
equipment.
