Isolated Programming Track Wiring

Set up a dedicated, isolated programming track with safe switching for decoder work.

Wiring Steps

1
Isolate a track section using insulated joiners at both ends of both rails
2
Connect programming track output from your command station
3
Install DPDT switch to select between main and programming power
4
Wire switch to disconnect main power when programming is selected
5
Add indicator LED to show programming mode is active

Tips for Success

Never have main track power connected while programming
Programming current limits protect decoders during setup
Some command stations have automatic track switching
Keep programming track long enough for your longest locomotive
Auto-reverser should NOT be on programming track

Safety Reminder

Always disconnect power before working on wiring. Double-check all connections before applying power. When in doubt, use a multimeter to verify your work.
