Goal: Train a $50 used O-scale locomotive to run as smoothly as a $500 brass model.
Step 1: The Roller Burnish (Penny Trick #2)
Remove the shell of a diesel or the boiler of a steam locomotive. Locate the center rail pickup rollers (usually 2–4 per engine). Using an old penny held in needle-nose pliers, gently roll the penny over the surface of each roller while rotating it. The copper in the penny burnishes the roller without removing metal. After 30 seconds per roller, you’ll see a shiny, smooth contact surface. Cost: $0.01 (same penny).
Step 2: Gearbox Simplicity
Open the gearbox. Remove old grease (which turns into waxy glue over time) using a toothpick and a drop of mineral spirits. Relubricate with one drop of light machine oil (3-in-1 blue bottle, not the red household kind) on the worm gear and one tiny dab of white lithium grease on the axle gears. Over-lubrication is the #1 killer of smooth running – it migrates to wheels and pickups, causing stutters. Penny Pax says: less is more.
Step 3: The Low-Voltage Schooling
Place the locomotive on a 3-foot test track. Using a variable transformer (any old Lionel or MRC throttle), run the engine at the lowest possible voltage that produces motion – usually 3–5 volts AC/DC depending on the motor. Run it forward for 10 minutes, then reverse for 10 minutes. Do not increase speed. This “schooling” aligns the brushes, seats the bearings, and wears in gear teeth without generating excess heat. Repeat this low-voltage training for three consecutive days. Cost: electricity negligible. penny pax training of o
Result: A locomotive that will crawl through a #4 turnout at a scale 2 mph without stuttering.
Goal: The dog self-interrupts the unwanted behavior.

That choice—to not jump—is the "O" (Offset of the unwanted behavior). Reward that choice 10x more generously than the correction.
In the world of balanced canine behavior modification, few tools are as controversial—or as effective in the right hands—as the Penny Pax. The “Pax” (Latin for peace) refers to the goal of a calm, neutral state in the dog. The "Training of O" refers to Operant conditioning focused on the Offset of a behavior—teaching a dog that ceasing an unwanted action leads to reward.
This method is not for simple sit/stay commands. It is designed for interrupting and extinguishing hardwired, self-rewarding behaviors like: Polarizing: praised for literary craft by some; condemned
The "O" also stands for Orientation shift—the dog learns to orient toward the handler upon hearing a specific metallic chime, rather than focusing on the trigger.
Goal: Condition the dog that the penny sound precedes a treat.
Do NOT use the sound to stop behavior yet. You are building a Pavlovian response: Sound = snack.
