Automatic DCC Control of MTH 3-Rail O ga. Proto 3 Alco S2 Diesel


This video shows an MTH 3-Rail O ga. Proto 3 Alco S2 Diesel — automatically running back & forth “point-to-point” — being controlled by an NCE DCC Power Cab & an NCE Mini Panel.

Drawings and sketches are here:

The Video #822 “information page” for the automatic control Video #822 is on the main site at ; there are also “information pages” for the earlier 2 videos.

There are so-far 3 videos in this O-gauge series (a 4th video is planned):

Video 668: Z-Stuff DZ-1012 Signal Automatically Controls 2 3-Rail O-Gauge Trains

This recent video shows a Z-Stuff Infrared Block Signal Detector and Relay automatically controlling two 3-rail O-gauge trains, running on the same track.

Although the demos use O-gauge trains, this detector-relay combination should be able to control trains of just about ANY gauge, 3-rail or 2-rail — using AC, DC, or DCC track power.

2017 Compilation Video:

  • Compilation Video #611 (used in the clinic at the 2017 National Association of S Gauger’s convention: VimeoYoutube (15 min)
    • This video shows 9 analog (DC track power) setups, and 9 DCC setups.

Not Shown in the Compilation Video

    • Some of the Large-scale demonstrations are NOT in this video, since it was made for the S gauge convention.
    • The two O-gauge videos mentioned above (#667 & #668) are not shown,  because they were made later.
    • Video #819 showing 3 DCC HO trains being controlled on the same mainline with NO turnouts — was made AFTER the compilation video.
