Cheat Sheet
- Fundamentals of CN USOR Air Brake Tests -
Review mandatory Class I air brake tests outlined in CN USOR Section 138.10 and FRA 49 CFR 232 to verify brake pipe reductions of 15 psi within 15 seconds for a 100-car train. Use the mnemonic ΔP = R × T (Pressure drop = Rate × Time) to remember application and release rates. Consistent brake cylinder pressure above 70% of full service ensures reliable stopping power.
- Hand Signal and Radio Communication Protocols -
Solid conductor exam prep includes mastering official hand signals from the Canadian Rail Operating Rules (CROR) Section 30 and CN USOR guidelines to ensure clear, nonverbal crew communication. Pair each gesture with a radio call sign (e.g., "Go - Engine One Off") to reinforce understanding during a conductor practice test or railroad safety quiz. A helpful mnemonic is "Yes/No/Slow/Stop" in sequence to drill common commands under pressure.
- Train Securing Procedures on Grades -
In CN USOR Section 137.3, secure equipment using the three-point method: Apply air brakes, set hand brakes, and chock wheels when required. Use the memory aid "AHS" (Air, Hand, Secure) to recall each step under exam conditions. Understanding slope tables and minimum hand brake counts (e.g., one brake per ten cars) is vital for safe operations.
- Hazardous Materials Handling and Placarding -
Familiarize yourself with the Transportation of Dangerous Goods Act classifications and CN USOR Section 501 to identify placard classes and emergency response guides (ERG). Practice labeling a tanker car with the correct placard number (e.g., Class 3 for flammables, ERG 127) during your rail operations test. This foundation boosts confidence for any CN USOR practice quiz on hazardous materials.
- Locomotive Pre-Departure Inspection Checklist -
Master the 22-point inspection outlined in CN USOR Section 161, covering brake rigging, traction motors, lighting, and fluid levels. Use the acronym "BATTLE FL" (Brakes, Air, Traction, Truck, Lights, Electrical, Fluids) to work through each item systematically. Practicing this checklist in a conductor practice test scenario improves retention and speeds up real-world inspections.
