The original video has been SPLIT UP into these 3 shorter videos:

* #820 "The Elusive DCC/DCS Switch on the MTH Proto 3, O-Gauge 3-Rail Locomotives": https://youtu.be/AfX7SavSJow or https://vimeo.com/370378341

* #821 "NCE DCC Power Cab Controls an MTH Proto 3, O ga. 3-Rail Alco S2 Diesel": https://youtu.be/ezE_1D1LV0g or https://vimeo.com/370579487

* #822 "Automatic Point-to-Point Control of MTH Proto 3, O ga. 3-Rail Diesel, using NCE DCC Mini Panel": https://youtu.be/lzhWvoTdcVY or https://vimeo.com/371224478

Comments About the Point-to-Point Operation

  • The third Video #822 shows an NCE DCC Power Cab & an NCE Mini-Panel, Automatically Controlling an MTH 3-Rail O ga. Proto 3 Alco Diesel -- running back & forth "point-to-point" -- using either a single reed switch and magnet, or alternately using a single Z-Stuff DZ-1011 infrared detector.

.

  • As demonstrated in the video, a pushbutton will cause the loco to make one "back and forth" cycle, or closing a switch will cause it to run back and forth continuously.
  • The idea is that on a DISPLAY, the PUBLIC could use the pushbutton to operate the loco (one cycle).
  • After the loco completes it's cycle, it loco will sit and idle -- until someone else comes along, and pushes the button again. 

.

In the NEXT video I hope to make in the future:

  • We can show a setup with a Z-Stuff DZ-1011 infrared detector at BOTH ends of the track, and have 2 buttons whereby the public (kids mainly) can hold down 1 button to make the train travel forward, and hold down the other button to make the train travel reverse.
  • When the train nears the end of the track and blocks one of the detectors, the Mini-Panel will prevent it from going any further.
  • This is demonstrated in Video #822 in Sect. 10 ( https://youtu.be/lzhWvoTdcVY?t=1592  ) -- using an S gauge diesel to demonstrate (I did this before I got the O gauge loco).

 

Comments About Using The NCE Power Cab

Note that NCE strongly recommends NOT using the Power Cab for O gauge -- but I had already recorded my video, and it worked fine for my demonstration.

  • My older Power Cab has a 1.3 amp power supply.
  • Newer Power Cabs have a 1.8 amp power supply.
  • These are fixed at 13 volts (determined by the power supply).

 

  • Since this MTH diesel can pull about 3.1 amps fully loaded, I have to operate my diesel with very light loads -- so as not to exceed my 1.3 amp capacity.
  • I still believe the Power Cab could be used to successfully operate a small loco with only 2 or 3 cars around a Christmas Tree or on a Dept. 56 display -- but I could be wrong about this due to my lack of experience with O gauge.
Original Post

I would just suggest that you keep the smoke turned off to help here.

BTW, I haven't ever stalled a MTH diesel or steamer. My MTH 2 rail doesn't have traction tires. I do run their 3 rail and also there G scale with traction tires.

How many volts is the power supply?

Why go back to DCC when I have DCS!

I DO have smoke turned off on this loco.

Voltage is 13 volts, determined by power supply (I added this to original post).

Thanks. I asked thinking you might have been able to raise the track voltage. Hopefully that might have lowered the amps.

I see you can't. I run my outside G scale higher and that shows lower amp draws on the meters. I have run five diesels in a consist with surprisingly lower amp draws like this. I remember when I first got a USA trains G scale diesel. I thought it was power hungry. After installing DCS inside and raising the track voltage, it's no problem at all.
