Q

3 fundamental elements to railway train control

A

Movement authorities
- Safe operation requires that access and operational practices for all sections of track is strictly controlled

Communication
- means by which status of specific sections of track is monitored and operating instructions provided to trains

Speed control
- necessary for traffic control requirements and civil infrastructure constraints

Q

Methods of operation abbreviations

A

ABS automatic block system

CTC centralized traffic control

DTC direct train control

MBS manual block System

TWC track warrant system

Other than main track

21
Q

Uncontrolled track

A

Not directly supervised

Doesn’t mean out of track

Movement authority may be conveyed solely through the regulations given in rulebook

22
Q

Hierarchy of operating instructions

A

Operating rulebook

Operating timetable and instructions

General orders

Track bulletins

Track warrants or similar authorities

Shorter lifetime, more specific

23
Q

North American operating rules

A

Canadian Rail Operaing rules
CN US OR

CSX
NORAC
Norfolk Southern
GCOR General code of Operating Rules

24
Q

Operating timetable

A

Basis for train operation on a specific portion of railroad (division/district)

Contains
Station List
Special instructions
NO! Times

In effect for months/years

25
Q

Track bulletins

A

Issued to individual trains, group of workmen

Ensures awareness of
general order in effect
Infrastructure changes

Relatively short lifetime

26
Q

Track warrants

A

Written document to convey movement authority

27
Q

GCOR 1:

General Responsibilities

A

Safety
Actions when accident/injury
Personal conduct rules
Duties of crew members

28
Q

Accident rate history

A
  • 79% since 1980

- 42% since 2005

29
Q

33
Q

GCOR 6
Movement of trains
Includes:

A

Repeating instructions prevent misunderstanding

Written instructions safer

Movement authority needed

Defines
Meet/pass

Yard limits

Restricted speed

34
Q

Restricted speed

A

Must be able to stop at a range half of the vision

Maximum 20mph

35
Q

GCOR 7 is about

A

Switching

Maximum speed for coupling 4mph

Switching is high risk operation

36
Q

GCOR 8 is about

A

Switches

  • must be locked when not in use

Normal Postillion must be lined and locked (except in use)

Employees lining switches must go on opposite side of track while train is switching

Train not considered clear of track until switch is lined back in normal position

37
Q

Timetables are giving context for

A

Define operating protocols for
Yard limits
TWC
CTC

Define where protocols are in effect

Information about
Speed restrictions
Close physical clearances
Special behavior to follow
(Example: mountain grades)
38
Q

Internal stimuli that act upon the railroad

A

Routine maintenance

Inspections

39
Q

External stimuli that act upon then railroad

A

Severe weather conditions and seismic activity

Public events
Police and fire activity
Public works projects

40
Q

String chart deciption of Different causes of train delay

A

Meet
Slow-meet
Trailing-pass (with and without train 2 stop)
Trailing

41
Q

Graphical train diagrams are

A

Useful visual aid for understanding train movements over a line

Facilitates train management
Scheduling timetables

Evaluate conflicts
Understand effect of changes on line capacity

42
Q

On sight operations

A

Locomotive haul started 1830

Soon access and right of way had to be controlled

43
Q

Timetable operation

A

Gives information where a conflicting train would NOT be a a given time

Rear end collision solved with 10minute Intervall

Flag protection however difficult

44
Q

Time balls

A

Used as long distance visual communication

Limited usefulness

45
Q

Significance of the telegraph

A

Enables fast communication

Needs skilled telegraphers

Telegraph Locations stationary

Trains between stations out of communication

Made transfer of movement authority possible

Facilitates centralization of control

Advance in efficiency

46
Q

Superiority of trains

A

A train is superior to another train by
Right
Class
Direction

This enables dynamic responds to delays

47
Q

Train orders

A

Train order signals notify the engineer if he has to stop or reduce speed

Order gives new information about meetings

48
Q

Safety protocols

A

Station Names and numeric figures were spelled out
7 = Seven

Content of order was checked by all stations listening
Repeated by everyone listening
