GCOR - General Code of Operating Rules Handling Switches and Derails Questions and Answers

Question 1

An employee has finished using a hand-operated main track switch for a switching move. After the entire movement is clear of the switch, what is the final required action regarding the switch's position?

Accepted Answer

Line and lock the switch for the main track.

Answer

GCOR Rule 8.3 states that the normal position of a main track switch is for main track movement and it must be lined and locked in that position after use, unless specific exceptions apply (such as being attended or under dispatcher authority).

Question 2

According to GCOR Rule 8.2, who bears the ultimate responsibility for the position of a hand-operated switch while it is in use?

Accepted Answer

The employee who is operating the switch.

Answer

GCOR Rule 8.2 explicitly states that the employee handling or operating the switch is responsible for its position. This is a rule of personal responsibility.

Question 3

A train is authorized to enter a yard track protected by a derail. Before the train occupies the track, what must be done with the derail?

Accepted Answer

The derail must be removed from the rail or placed in the non-derailing position.

Answer

The purpose of a derail is to protect another track (often the main track) from an unauthorized movement. The derail must be placed in the non-derailing position to allow equipment to safely enter the track it protects.

Question 4

When making a trailing point movement over a spring switch, which of the following is a primary requirement before proceeding?

Accepted Answer

A crew member must observe that the switch points are closed and fit properly.

Answer

For a trailing point movement over a spring switch, the points are forced open by the wheels and then spring back. It is critical to ensure the points are properly closed before the movement starts to prevent a derailment. Testing the switch by hand (lining it over and back) is required only for certain facing point movements under specific signal indications.

Question 5

A crew needs to use a hand-operated crossover between two main tracks. What is the correct procedure for lining the switches?

Accepted Answer

Both switches of the crossover must be opened and properly lined before the movement begins.

Answer

GCOR Rule 8.12 requires that both switches of a crossover must be opened and lined for the crossover movement before the movement starts. This ensures a continuous and safe route.
