Operating Instructions
Basic Operation (DCC)
- Placing on Track: Carefully place the locomotive on the track, ensuring all wheels are properly seated on the rails.
- Power On: Turn on your DCC system. The locomotive should respond with an initial sound sequence.
- Addressing the Locomotive: The locomotive is pre-programmed with a default DCC address (typically 3). Refer to your DCC system's manual for instructions on how to select and change locomotive addresses.
- Controlling Speed: Use your DCC throttle to control the locomotive's speed and direction. Increase the throttle gradually for smooth acceleration.
- Controlling Lights:
- Headlights/Taillights: Typically controlled by Function 0 (F0) on your DCC throttle.
- Ditch Lights: Operating ditch lights are a feature of this model. Consult your DCC system's manual and the locomotive's specific function mapping for activation (often F6 or F7).
- Controlling Sound Functions: This model includes a full sound suite. Common sound functions include:
- Horn (Nathan K5LA): Typically F2.
- Bell: Typically F1.
- Coupler Crash: Often F3 or F4.
- Dynamic Brake: Often F5.
- Volume Control: Some decoders allow volume adjustment via a function key or CV programming.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your Athearn HO GP40-2L locomotive.
Cleaning
- Wheels: Periodically clean the locomotive's wheels with a soft cloth and a small amount of rail cleaner to ensure good electrical contact with the track.
- Track: Keep your track clean. Dust and dirt are major contributors to poor locomotive performance.
- Body: Use a soft, dry brush or cloth to gently remove dust from the locomotive body. Avoid using harsh chemicals or abrasive materials.
Lubrication
Light lubrication of moving parts is recommended every 20-30 hours of operation or annually, whichever comes first. Use only plastic-compatible model railroad lubricants.
- Axle Bearings: Apply a tiny drop of light oil to the axle bearings where the axles pass through the sideframes.
- Worm Gears: A very small amount of grease can be applied to the worm gears if accessible. Refer to advanced maintenance guides or seek professional assistance if unsure.
Note: Excessive lubrication can attract dust and hinder performance. Apply sparingly.
