Answer to Question 13:
Even if you’re using a basic DC setup, don’t rely on rail joins alone to carry power.
Solder feeder wires (dropper wires) from the track to a power bus beneath the baseboard.
This ensures:
- Consistent power
- Fewer dead spots
- Easier fault finding
Use colour-coded wire, red for positive, black for negative and keep your wiring tidy with cable clips or ties.
If you’re going DCC (Digital Command Control), spacing your feeders becomes even more important.
