3. Setup Instructions
3.1. Unpacking
Carefully remove the Lionel 62900 Power LocKon from its packaging. Inspect the unit for any visible damage that may have occurred during shipping. If any damage is observed, do not proceed with installation and contact customer support.
3.2. Connecting the LocKon to Track
The Power LocKon is designed for easy attachment to Lionel O and O27 gauge tubular track sections. Follow these steps for proper connection:
- Select Track Section: Choose a straight or curved section of O or O27 tubular track where you wish to supply power. Ensure the track is clean and free of debris.
- Position LocKon: Place the LocKon on the track so that its metal clips align with the outer and center rails of the track.
- Attach Clips: Gently press down on the LocKon until the metal clips firmly grip the rails. Ensure a secure connection to both the outer and center rails. The clips should snap into place, providing a stable electrical contact.
- Verify Connection: Wiggle the LocKon gently to ensure it is securely attached and does not easily detach from the track.

3.3. Connecting to Power Source
Once the LocKon is securely attached to the track, connect it to your model train transformer or power supply:
- Turn Off Power: Ensure your transformer or power supply is turned off and unplugged from the wall outlet.
- Identify Terminals: The LocKon has two screw terminals. These correspond to the common (ground) and hot (power) outputs of your transformer. Refer to your transformer's manual for specific wiring instructions.
- Connect Wires: Strip a small amount of insulation (approximately 1/4 inch) from the ends of your power wires. Loosen the screws on the LocKon terminals, insert the bare wire ends, and tighten the screws firmly to secure the connection.
- Verify Wiring: Double-check that the wires are correctly connected to the appropriate terminals on both the LocKon and the transformer. Ensure no stray wire strands are causing a short circuit.
4. Operating Instructions
With the LocKon properly installed and connected to your power source and track, you are ready to operate your model train layout.
4.1. Powering the Track
The Lionel 62900 Power LocKon acts as a conduit for electrical current from your transformer to the track rails. Once the transformer is turned on, power will flow through the LocKon to the track, enabling your locomotive and other track-powered accessories to function.
4.2. Basic Operation
- Turn On Transformer: Plug in and turn on your model train transformer.
- Control Train: Use the controls on your transformer to adjust the speed and direction of your locomotive.
- Monitor Performance: Observe your train's operation. If there are any interruptions in power or erratic behavior, refer to the Troubleshooting section.
5. Maintenance
Regular maintenance helps ensure the longevity and reliable performance of your Lionel 62900 Power LocKon.
- Cleaning: Periodically wipe the LocKon with a dry, soft cloth to remove dust and grime. Do not use liquid cleaners or solvents.
- Connection Check: Regularly inspect the metal clips for corrosion or bending. Ensure they maintain a tight grip on the track rails. Clean track rails as needed to ensure good electrical contact.
- Wiring Inspection: Check the power wires connected to the LocKon for fraying, cuts, or loose connections. Re-tighten screw terminals if necessary.
- Storage: When not in use for extended periods, store the LocKon in a dry, cool place away from direct sunlight and extreme temperatures.
