To clean model train wheels, you can use methods ranging from simple scraping and running the locomotive to utilizing dedicated cleaning tools and fluids.
Keeping model train wheels clean is crucial for smooth operation and reliable electrical pickup, which is essential for power and control, especially in DCC systems. Dirt, grease, and grime can build up on the wheel surfaces, causing erratic running, stalling, and flicker lights.
Simple Cleaning Methods
One basic approach involves physically removing accumulated dirt from the wheels. The provided reference describes a method using a scraper and then running the locomotive.
Scraping and Running (Method Referenced)
As suggested in locomotive maintenance tips, you can directly address the dirt on the wheels:
- Scrape the dirt: Use a tool to carefully scrape the dirt off the wheel surfaces. This helps dislodge stubborn grime.
- Run and Reverse: After scraping, place the locomotive on the track and run it for a short period in one direction. Then, change direction and then set it off again. This back-and-forth motion can help further clean the wheels against the rails and distribute any remaining lubricant or cleaning residue evenly.
This method serves to scrape the dirt off the wheels and help push the wheels and clean them up at the same time by running on the track.
Other Effective Cleaning Techniques
Beyond the simple scraping and running method, several other techniques are commonly used by model railroaders for more thorough cleaning:
- Cleaning Pads or Blocks: Special abrasive or chemically treated pads and blocks are available. You can hold these against the wheels while the locomotive sits on a powered track or a roller stand, allowing the rotating wheels to clean themselves against the pad.
- Practical Tip: Always lift the locomotive slightly to apply gentle pressure, avoiding damage to the motor or mechanism.
- Cotton Swabs and Cleaning Fluid: Dip a cotton swab in a small amount of dedicated model railroad cleaning fluid (like contact cleaner or isopropyl alcohol – check what is safe for your specific models). Gently rotate the wheels by hand while cleaning the contact surface with the damp swab.
- Caution: Avoid flooding the locomotive with liquid, as it can damage motors, gears, or plastic parts. Ensure good ventilation when using solvents.
- Track Cleaning Cars: Some model railroaders use dedicated track cleaning cars that can also help clean locomotive wheels indirectly as they run. These cars often have pads or abrasive surfaces that contact the rails, and the locomotive wheels pick up some of this cleaning action.
- Roller Stands: For easier and safer cleaning with pads or swabs, a roller stand allows the locomotive's wheels to spin freely while it is held stationary.
Regular cleaning using methods like scraping, running forward and backward, or employing dedicated cleaning tools will ensure your model trains run reliably and provide consistent performance on your layout.
