Question 1

ACKNOWLEDGING DEVICE

Answer 1

The button, pedal or switch that must be operated to prevent a Train Control Apparatus initiated penalty application of train breaks when the cab signals changes to a more restrictive aspect or as required to prevent an alerter system penalty break application

Question 2

ALERTER SYSTEM

Answer 2

A safety device that ensures operator alertness and requires periodic acknowledgment to prevent a penalty break application.

Question 3

ANGLE COCK

Answer 3

The pneumatic shut off valve for the break pipe connections between units other than M-series equipment in a train consist. In “open”position, the valve handle is aligned with the pipe. 

Question 4

AUDIBLE INDICATOR

Answer 4

The device that provides an audible annunciation, when the cab signal changes to a more restrictive aspect, when the train exceed the speed authorized by Train Control, Apparatus, or when the alertness system is activated.

Question 5

AUTOMATIC AIR BRAKE

Answer 5

The primary break system of a train in which the reduction of brake pipe pressure will apply the brakes.

Question 6

AUTOMATIC TRAIN CONTROL (ATC)

Answer 6

A train control apparatus that initiates a penalty break application if the engineer fails to reduce speed in conjunction with the signal indication.

Question 7

AUTOMATIC TRAIN STOP

Answer 7

A train control apparatus that initiate a penalty break application if the engineer fails to acknowledge a more restrictive cab signal aspect.

Question 8

** BRAKE CYLINDER (BC)**

Answer 8

The device in which compressed air acts on a piston to transmit a pneumatic forced to apply break forces to the wheel

Question 9

BRAKE PIPE (BP)

Answer 9

The system of piping including branch pipes, angle cocks, cut out cocks, dirt collectors, hose and hose couplings, used for connecting the units of a consist in order to trainline, air pressure for the operation of the automatic brake system.

Question 10

BRAKE PIPE GRADIENT

Answer 10

The difference in the break pipe pressure between the lead locomotive and rear end of a train.

Question 11

CAB SIGNAL DAILY TEST

Answer 11

A test of the Train Control Apparatus performed by a QMP.

Question 12

CAB SIGNAL DEPARTURE TEST

Answer 12

A test of the Train Control Apparatus performed by the locomotive engineer.

Question 13

CLASS 1 BRAKE TEST

Answer 13

A comprehensive passenger train brake system test and inspection performed by a Qualified Maintenance Person (QMP) to ensure that the air brake system is 100% effective 

Question 14

** CLASS 1A BRAKE TEST**

Answer 14

A brake test and inspection performed by a Qualified Person who may be a member of the road crew, to determine the air brakes on each unit of a passenger train consist apply and release in response to train line commands.

Question 15

** CLASS 2 BRAKE TEST**

Answer 15

Test and inspection of braking system performed by a QP or QMP to ensure break pipe integrity in continuity from the controlling unit of a train to the rear end of a passenger train.

Question 16

CONSIST CALENDAR DAY

Answer 16

The daily equipment operating cycle of a passenger train on one day. Completion of the cycle for late night trains in continuous service may extend beyond 23:59 hours on that given date.

Question 17

DEAD ENGINE FEATURE

Answer 17

A feature of the air brake system by means of which the main reservoir is change from the brake pipe.

Question 18

DISK BRAKES

Answer 18

A retardation system that utilizes a flat metal disc attached to the axle and/or the wheel of the unit as the braking surface instead of the wheel tread.

Question 19

DYNAMIC BRAKE

Answer 19

A secondary braking method, whereby the inertia from a train’s motion is translated into electrical energy and then dissipated as he threw resistors or regenerated into the third row or auxiliary power.

Question 20

**ELECTRO-PNEUMATIC BRAKE (EP)

Answer 20

An electrically controlled system that applies and releases the primary service air brake on a unit utilizing an electrical trainline in lieu of brake pipe pressure.
