PTS Critical Communications 3

Question 1

A worker receives a mandatory directive (MD) from the dispatcher. What must the worker do?

Accepted Answer

Record the MD number and read back the key contents for verification

Answer

Mandatory directives require the worker to record the MD number and read back key information to confirm accuracy before acting on the directive.

Question 2

Which communication method has the LOWEST reliability for track safety warnings and should not be used as the sole means of protection?

Accepted Answer

Verbal shouts between workers

Answer

Verbal shouting is unreliable due to ambient noise from equipment, wind, and train sound, and must not serve as the sole warning method.

Question 3

What action should a gang foreman take if radio contact with the dispatcher is lost during active track work?

Accepted Answer

Immediately suspend work and move workers clear of the track

Answer

Loss of communication with the dispatcher during active track work requires immediate work stoppage and track clearance until communications are restored.

Question 4

What information must a roadway worker provide when calling the dispatcher to establish track and time authority?

Accepted Answer

Location (milepost/subdivision), number of workers, equipment, and requested limits of authority

Answer

When requesting authority, workers must provide their location, the number of personnel and equipment, and the requested track limits so the dispatcher can grant precise protection.

Question 5

Under what circumstance may a roadway worker share their track authority with another worker?

Accepted Answer

Authority may not be shared; each protected zone requires its own authority

Answer

Track authority is granted to a specific individual or gang and cannot be shared with others who must obtain their own separate authority for protection.
