DEFINITIONS BLOCK-A length of track of defined limits, the use of which is governed by block signals, cab signals, or both, or Manual Block Rules. MANUAL BLOCK-A block, the control of which is maintained by a designated employe, through the use of communications, for which Manual Block Rules are in effect. BLOCK MARKER-A sign of fixed location indicating the limit of block.
BLOCK SYSTEM-A series of consecutive blocks. AUTOMATIC BLOCK SYSTEM (ABS) --A series of consecutive blocks governed by block signals, cab signals, or both, actuated by a train, or engine, or by certain conditions affecting the use of a block .MANUAL BLOCK SYSTEM (MBS) -- A block, or series of consecutive blocks for which Manual Block Rules are in effect. TRAFFIC CONTROL SYSTEM (TCS) -- A block signal system under which train movements are authorized by block signals, cab signals, or both, whose indications supersede the superiority of trains for both opposing and following movements on the same track.
DIVISION-That portion of a railroad assigned to the supervision of a Superintendent. SUB-DIVISION-A portion of a division designated by Time Table.
ENGINE-A unit propelled by any form of energy or a combination of such units operated from a single control. CONTROL CAR-A passenger car equipped with engine and air brake controls, whereby it may control an engine located elsewhere in a train.
INTERLOCKING INTERLOCKING-An arrangement of signals and signal appliances so interconnected that their movements must succeed each other in proper sequence and for which interlocking rules are in effect. It may be operated manually, automatically, or by remote control (Controlled Point). INTERLOCKING LIMITS-The tracks between the home signals of an interlocking. ROUTE-The way or course which is, or is to be, traveled. PI LOT PILOT-An employe assigned to a train when the engineman or conductor, or both, are not fully acquainted with the physical characteristics or rules of the railroad, or portion of the railroad, over which the train is to be moved. SIGNALS FIXED SIGNAL-A signal of fixed location indicating a condition affecting the movement of a train, engine
or cars, and includes such signals as switch, train order, block, interlocking, semaphore, disc, stop boards, yard
limit boards, slow boards, or other means for displaying indications that govern the movement of a train, engine
or cars. APPROACH SIGNAL-A fixed signal used in connection with one or more signals to govern the approach thereto. BLOCK SIGNAL-A fixed signal at the entrance of a block to govern trains, engines or cars entering and using that block. INTERLOCKING SIGNALS-The fixed signals of an interlocking. HOME SIGNAL-A fixed signal at the entrance of a route or block to govern trains, engines or cars entering and using that route or block. DWARF SIGNAL-A low home signal. CAB SIGNAL-A signal located on an engine indicating a condition affecting the movement of a train or engine and used in conjunction with interlocking signals and block signals, or in lieu of block signals. SIGNAL ASPECT-The appearance of a fixed signal, conveying an indication as viewed from the direction
of an approaching train; the appearance of a cab signal conveying an indication as viewed by an observer in the
cab of an engine or control car. SPEEDS NORMAL SPEED-The maximum speed permitted by Time Table or General Order for a designated track. LIMITED SPEED-A speed not exceeding forty-five (45) miles per hour. MEDIUM SPEED A speed not exceeding thirty (30) miles per hour. SLOW SPEED-A speed not exceeding fifteen (15) miles per hour. REDUCED SPEED-Proceed prepared to stop short of train or obstruction. RESTRICTED SPEED-Proceed prepared to stop short of train, obstruction, or switch not properly lined, but not exceeding fifteen (15) miles per hour. YARD SPEED-A speed that will permit stopping within one-half the range of vision. SPEED WHEN ACCEPTING APPROACH SIGNALS -- In conforming to the speed requirements when operating under
Rule 285, the train should not exceed Medium Speed when passing the signal. When the signal cannot be seen a sufficient
distance to reduce to Medium Speed before passing the signal, the speed should be reduced as soon as proper handling
of train will STATIONS BLOCK STATION-A place designated by Time Table as the limit of a block for which Manual Block Rules are in effect. INTERLOCKING STATION-A place from which an interlocking is operated. STATION-A place designated in the Time Table by name. CONTROLLED POINT (CP) -- A location where home signals and switches are remotely controlled. TIME TABLE TIME TABLE-The authority for the movement of regular trains subject to the rules. It contains classified schedules with special instructions relating to the movement of trains. SCHEDULE-That part of a Time Table which prescribes class, direction, number and movement for a regular
train. TRACKS MAIN TRACK-A track extending through yards and between stations, upon which trains are operated by Time Table or train order, or both, or the use of which is governed by block signals. SECONDARY TRACK-A track designated by Time Table or General Order upon which trains and engines may be operated without Time Table authority, train orders or block signals. SINGLE TRACK-A main track upon which trains are operated in both directions. CURRENT OF TRAFFIC-The movement of trains on a main track, in one direction, specified by the rules. SIDING-A track auxiliary to the main track for meeting or passing trains. CONTROLLED SIDING-A siding where movements are governed by signal indication, for which TCS Rules are in effect. SIDE TRACK-A track, other than a siding, auxiliary to the main track. YARD-A system of tracks provided for the making up of trains, storing of cars and other purposes, over which movements not authorized by Time Table, or by train order, may be made, subject to prescribed signals and rules, or special instructions. ELECTRICALLY LOCKED SWITCH-A hand operated switch equipped with an electrically controlled device which restricts the movement of the switch. SPRING SWITCH-A switch equipped with a spring mechanism arranged to restore the switch points to normal position after having been trailed through.
TRACK CAR TRACK CAR-A hand car or a self-propelled car. The term "Track Car" shall include such self-propelled
units as: Locomotive Cranes, Hy-Rail Cars, Weed Burners, Tie Tampers and other similar equipment. TRAINS TRAIN-An engine or more than one engine coupled, with or without cars, displaying markers. REGULAR TRAIN-A train authorized by a Time Table schedule. EXTRA TRAIN-A train not authorized by a Time Table schedule. It may be designated as:
SUPERIOR TRAIN-A train having precedence over another train. TRAIN OF SUPERIOR RIGHT-A train given precedence by train order. TRAIN OF SUPERIOR CLASS-A train given precedence by Time Table. TRAIN OF SUPERIOR DIRECTION-A train given precedence by direction as between opposing trains of the same
class. TRAIN REGISTER TRAIN REGISTER-A book or form used at designated stations for registering the time of arrival and departure
of trains and such other information as may be prescribed. |
