Package Contents
Verify that all components are present in your package:
- 1x Marklin HO 'M' Track Left-Hand Turnout (Model 5138)
- 1x Marklin HO 'M' Track Right-Hand Turnout (Model 5139)
- Associated wiring for electrical connection
- Control switches (if included in specific variant)
Setup and Installation
Follow these steps to correctly integrate the turnouts into your Marklin HO 'M' track layout.
- Track Preparation: Ensure your existing 'M' track sections are clean and free of debris. Plan the exact location for your turnouts.
- Connecting Turnouts: Carefully connect the turnout sections to your existing track. 'M' track sections interlock, so ensure a firm and flush connection.
- Electrical Connection:
- Each turnout requires electrical power for its electromagnetic mechanism. Connect the provided wires to the appropriate terminals on the turnout and to your control panel or switch box.
- Refer to your Marklin control unit manual for specific wiring diagrams for turnouts. Typically, a common ground wire and two control wires (one for each direction of the turnout) are used.
- Testing: Before securing the track, test the turnout operation. Apply power to your track system and activate the turnout control. The points should move smoothly and completely to both positions.

Operating the Turnouts
Marklin 'M' track turnouts are operated electromagnetically via a control switch.
- Connect the turnout's control wires to a compatible Marklin control switch (e.g., Marklin 72710 or similar).
- Pressing one button on the control switch will move the turnout points to one direction (e.g., straight).
- Pressing the other button will move the turnout points to the alternate direction (e.g., diverging).
- Ensure the turnout points are fully engaged in the desired position before a train passes over them to prevent derailments.

Maintenance
Regular maintenance ensures reliable operation and extends the lifespan of your turnouts.
- Cleaning Track Surfaces: Periodically clean the metal running surfaces of the track and turnout points with a track cleaning fluid or a soft, lint-free cloth. This prevents poor electrical contact.
- Point Mechanism: Keep the moving parts of the turnout points free from dust, lint, and debris. A small brush can be used for this. Avoid applying lubricants unless specifically recommended by Marklin, as they can attract dirt.
- Electrical Connections: Ensure all wire connections are secure and free from corrosion. Loose connections can lead to intermittent operation.
Troubleshooting
If your turnout is not functioning correctly, consider the following:
- Turnout Not Switching:
- Check all electrical connections from the control switch to the turnout.
- Ensure the control switch is receiving power.
- Inspect the turnout mechanism for any obstructions (e.g., debris, bent parts) preventing movement.
- Intermittent Operation:
- Clean track surfaces and turnout points thoroughly.
- Verify secure electrical connections.
- Derailments on Turnout:
- Ensure the turnout points are fully engaged in the correct position before a train passes.
- Check for any misalignment between the turnout and adjacent track sections.
- Inspect train wheels for cleanliness and proper gauge.
