.following .speed .control .apparatus, .a .cab .signal .indicator, .sealed .application
.valve .or .switch, .audible .warning .device .and .acknowledging .switch, .in .operative
.condition .for .the .direction .in .which .it .is .to .move.
Engine .(ENG) .- .CORRECT .ANSWER-A .unit .propelled .by .any .form .of .energy .or .a
.combination .of .units .operated .from .a .single .control, .used .in .road .or .yard

.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.
Interlocking .(INT) .- .CORRECT .ANSWER-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.
Interlocking .Limits .- .CORRECT .ANSWER-The .tracks .between .the .extreme
.opposing .home .signals .of .an .interlocking.
Pilot .- .CORRECT .ANSWER-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.
Aspect .- .CORRECT .ANSWER-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.
Block-Limit .Signal .- .CORRECT .ANSWER-A .fixed .signal .indicating .the .limit .of
.the .block, .the .use .of .which .is .governed .by .manual .block .signal .system .rules.
Block .Signal .- .CORRECT .ANSWER-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.
Cab .Signal .Indicator .- .CORRECT .ANSWER-A .signal .indicator .located .in .the
.engine .control .compartment .displaying .the .maximum .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.
Distant .Signal .- .CORRECT .ANSWER-A .fixed .signal .used .to .govern .the
.approach .to .a .home .signal.
Fixed .Signal .- .CORRECT .ANSWER-A .signal .of .a .fixed .location .indicating .a
.condition .which .affects .the .movement .of .a .train.
