1. Block A length of track of defined limits, the use of which is governed by block signals,
block-limit signals, automatic speed control or any combination thereof.
2. Absolute Block A block established between block stations, block limit stations, interlockings or any
combination thereof which must not be occupied by more than one train except
as provided by the rules.
3. Automatic Block A block signal system wherein the use of each block is governed by an automatic
Signal System block signal, the cab signal indicator or both.
4. Block Signal Sys- A series of consecutive blocks.
tem
5. Manual Block Sig- A block signal system wherein the use of each block is governed by block signals
nal System controlled manually, by block-limit signals or both, upon information received by
telephone, radio or other means of communication.
6. Automatic Speed A system so arranged that its operation will automatically result in the following:
Control System ( A full service application of the train brakes if, while operating under a speed
ASC ) restriction, the speed of the train exceeds the predetermined rate. The application
will continue until the train is either brought to a stop or, under the control of the
engineer, its speed is reduced to the predetermined rate.
7. Speed Controlled A train equipped with the following speed control apparatus, a cab signal indicator,
Train sealed application valve or switch, audible warning device and acknowledging
switch, in operative condition for the direction in which it is to move.
8. Engine (ENG) A unit propelled by any form of energy or a combination of units operated from a
single control, used in road or yard service.
9. Multiple Unit Equipment capable of being propelled by electrical energy through the use of third
Equipment rail contact shoes.

A roadway maintenance machine, not classified as an engine, which is operated
on track for inspection or maintenance. It may not shunt track circuits or operate
signals and will be governed by rules and special instructions for trains other than
passenger trains.
11. Interlocking (INT) An arrangement of signals and signal appliances so interconnected that their
movements must succeed each other in proper sequence and for which interlock-
ing rules are in effect.
12. Interlocking Lim- The tracks between the extreme opposing home signals of an interlocking.
its
13. Pilot An employee assigned to a train or track car when the engineer, conductor or track
car driver is not qualified on the physical characteristics or rules of the railroad or
portion of the railroad over which the movement is to be made.
14. Aspect The appearance of a fixed signal which conveys an indication as viewed from the
direction of an approaching train; the appearance of a cab signal indicator as
viewed in the engine control compartment.
15. Block-Limit Sig- A fixed signal indicating the limit of the block, the use of which is governed by
nal manual block signal system rules.
16. Block Signal A fixed signal or a hand signal in the absence of a fixed signal, at the entrance to
a block that governs trains using that block.
17. Cab Signal Indi- A signal indicator located in the engine control compartment displaying the max-
cator imum speed for the movement of the train. It will be used in conjunction with
interlocking signals and either in conjunction with or in lieu of block signals.
18. Distant Signal A fixed signal used to govern the approach to a home signal.
19. Fixed Signal A signal of a fixed location indicating a condition which affects the movement of a
train.
