Bailey Base Bus

| Symptom | Likely Cause | Solution | |---------|--------------|----------| | Locos stall at module joints | Drop wires missing near joint | Add droppers within 50mm of each module edge. | | Intermittent DCC short | Connector pins misaligned | Use locking circular connectors (e.g., SpeakON). | | Voltage drop at far end | Bus too thin or too long | Upgrade to 2.5mm² wire; add a power booster. | | DCC signal interference | Bus wires untwisted, too long | Twist wires; add a DCC terminator (120Ω resistor + 0.1µF cap). | | Module disconnected but track still live | Backfeed via accessory bus | Separate track bus from accessory bus with diodes or opto-isolators. |
