- Inspect for obstructions: Look for any debris or foreign objects on the track or in the locomotive's mechanism.
6.2 Derailment
- Verify track alignment: Ensure all track sections are securely connected and properly aligned, especially on curves.
- Check wheel gauge: Ensure the locomotive's wheels are correctly gauged for N scale track.
- Reduce speed on curves: Operating at excessive speeds on curves can lead to derailment.
6.3 Headlight Issues
- Confirm power: Ensure the locomotive is receiving power from the track.
