Which flag color signals that workers must immediately clear the track because a train is approaching?

Accepted Answer

Red

Answer

Question 2

A dispatcher issues a track bulletin restricting speed in a work zone. Which party is responsible for informing train crews of this restriction?

Accepted Answer

The dispatcher communicates the track bulletin to train crews through established railroad operating procedures

Answer

Dispatchers communicate track bulletins, slow orders, and other restrictions to train crews through the railroad's standard operating bulletin system.

Question 3

What must a work group do before beginning any track work after an unplanned interruption (e.g., equipment breakdown, personnel change)?

Accepted Answer

Conduct a job safety briefing to re-establish on-track safety and confirm all workers understand current protection

Answer

Any significant interruption requires a safety briefing to re-confirm the method of on-track protection and ensure all workers — including any newcomers — understand the current safety status.

Question 4

What does 'fouling the track' mean in PTS communications?

Accepted Answer

Any person, equipment, or material positioned close enough to be struck by a passing train

Answer

Fouling the track means being within the danger zone — the minimum clearance distance — where a passing train or its load could make contact.

Question 5

Under PTS rules, when does a gang foreman's track authority expire?

Accepted Answer

When the train dispatcher calls to check in

Answer

Authority expires at the limits specified — either the time, milepost limits, or when the foreman formally releases it to the dispatcher, whichever occurs first.
