Read the first 6 GCOR - General Code of Operating Rules Train Handling and Speed Restrictions flashcards as text

  1. Under GCOR, what must a locomotive engineer do before exceeding the maximum authorized speed when conditions improve?

    Answer: Ensure all restrictions have been cleared and conditions permit

    Engineers must confirm all speed restrictions are lifted and conditions permit before increasing speed to the authorized maximum.

  2. According to GCOR, what is the maximum speed allowed when moving against the current of traffic on a double main track without a specific authority?

    Answer: 10 mph

    GCOR restricts movement against the current of traffic on double main track to a maximum of 10 mph unless specific authority is granted.

  3. Under GCOR, when must an engineer reduce speed to 20 mph or less at grade crossings not equipped with automatic warning devices?

    Answer: Always, regardless of visibility

    GCOR requires trains to reduce to 20 mph or less at all passive grade crossings (those without automatic warning devices) regardless of conditions.

  4. When a GCOR train must stop and the engineer cannot stop within half the range of vision, what action is required?

    Answer: Apply emergency brakes and sound the horn

    When unable to stop within half the range of vision, GCOR requires the engineer to apply emergency brakes and sound the horn to warn others.

  5. Under GCOR, what speed restriction applies to a train with defective or inoperative dynamic brakes on grades exceeding a specific percentage?

    Answer: The train must not exceed the speed authorized by the chief mechanical officer or equivalent

    GCOR requires that when dynamic brakes are defective on steep grades, the speed must not exceed what is authorized by the designated mechanical authority.

  6. According to GCOR, what must occur before a train exceeds 49 mph when operating with a distributed power unit (DPU)?

    Answer: Communication and control of the DPU must be verified as operational

    Before exceeding 49 mph with a DPU, GCOR requires verification that communication and control of the distributed power unit are fully operational.
