Quick Summary

  • Do not use track power
  • Most accessories run 12-14V
  • Use a dedicated accessory supply
  • One common ground for all

Standard Voltage

  • Buildings and lights: 12-14V
  • Uncoupler tracks: 10-12V
  • Switches: 14V constant

Basic Setup

  • Accessory transformer
  • Terminal block or distribution point
  • Common return wire

Rule: One common ground shared, one hot feed per accessory.

Example 1: Uncoupler Track

Problem: Train slows or stops when activating.

Fix: Use accessory power, set 10-12V, and use momentary activation only.

Example 2: FasTrack Switch

Problem: Weak throw or failure.

Fix: Use a dedicated 14V supply and keep it separate from track power.

Example 3: Lighted Accessories

Problem: Bulbs burn out early or run dim.

Fix: Use a stable 12-14V fixed voltage source.
