KB181: Single Programming Track - Multiple Programming Sources

This article was last updated on Jan. 12, 2012, 3:03 a.m. | Print Article | Leave Feedback

How can I connect my PR3 programming output to an existing programming track on my layout that is already set up for programming and mainline operations?

Install a non shorting multi position rotary switch between a isolated section of track, 4-6” longer than your longest engine, and the various desired outputs from command stations and the PR3 output terminals.

The following schematic allows a single section of track to be fed by the rail output of a command station, the programming track output of a command station, and the programming output of a PR3.
To add other third party decoder programmers to this configuration only requires using a non shorting rotary switch with additional positions wired in the same manner as the above outputs.
