GCOR Questions and Answers

What does GCOR stand for?

GCOR stands for the General Code of Operating Rules, a standardized rulebook governing train operations across most Class I, regional, and short line railroads in the western United States. It was first adopted in 1985 to unify operating practices and is maintained by the GCOR Committee, with the 7th edition currently in use.

How many questions are on the GCOR exam?

The GCOR certification exam typically contains 50 to 100 multiple-choice and true/false questions, though the exact count varies by railroad and job classification. Union Pacific and BNSF often use 75-question versions, while conductor and engineer exams may include additional scenario-based questions covering specific operating rules.

What is the passing score for the GCOR exam?

Most railroads require a minimum passing score of 85% on the GCOR exam, though some carriers like BNSF and Union Pacific require 90% or higher for safety-critical positions such as conductors, engineers, and dispatchers. Failing requires remedial training before a retest is permitted.

Is the GCOR exam open book or closed book?

The GCOR exam is typically administered as a closed-book test, though some railroads allow candidates to reference the rulebook for certain sections during initial certification. Recertification exams are almost always closed-book and computer-based, completed at railroad training centers or approved testing facilities.

How long do I have to complete the GCOR exam?

Candidates are generally given 90 to 120 minutes to complete the GCOR exam, depending on the railroad and the number of questions. Initial certification exams may allow up to 3 hours, while recertification tests are usually shorter at 60 to 90 minutes.

Do I need prior experience to take the GCOR exam?

No prior railroad experience is required, but candidates must complete their employer's formal training program before testing. New hires typically attend 4 to 8 weeks of classroom instruction covering GCOR rules, air brake regulations, and timetable special instructions before being eligible to sit for the exam.

How do I register for the GCOR exam?

Registration is handled directly through your employing railroad's training department, not through a public testing agency. Once you complete required coursework, your trainer or manager schedules the exam at a company testing center. The GCOR exam is not available to the general public outside railroad employment.

What study materials are recommended for the GCOR exam?

The official GCOR 7th Edition rulebook is the primary study resource, supplemented by your railroad's timetable, special instructions, and air brake rules. Practice tests, flashcards for rule numbers like Rule 6.5 (shoving movements) and Rule 5.3.1 (signal indications), and study guides from trainers help reinforce key operating concepts.
