- How to install an automated Back and Forth reversing system on a point to point model train layout using an easily programmable Relay Board is described. Used for a train , Trolley or Locomotive.
Just made a setup that fits in a window sill for a Christmas Train, The reversing unit came with good Documentation, but nothing like watching a video. The segment in your video on using the program button I watched a half dozen times. Video was well done. Working on this in June to be ready for the Christmas season this year. Thanks.
Beautiful! Exactly what I was looking for at an amazingly low price. Very nicely done. Can't wait to give it a try!
Thanks again. Just ordered a reversing circuit from your website. Your explanations, diagrams and notes are exceptional. Looking forward to installing it.
Great description ...fully explained .... If I get some courage ,Id try it some day.
We just ordered this off of eBay! We're excited!
Thank you so much. What a great help this video is. It's very much apriciated. 👍🏻 The relay is clicking away nicely here on the bread board temporary set up to the timings I desire. Now to get the lot onto the track. Again brilliant video. Thank you.
Why is this not a standard kit option from Lionel? I was searching for something like this for a Christmas handcar I have. Just bought this kit from your site. Thanks! Now hopefully I can wire it up properly.🤔
thanks for you info
This is awesome! I've been toying with the idea of making a little diorama but don't have the space for a circuit. Love the idea of using two of these and having two straight lines going through a station back and forth. Would be a great amount of motion for a tiny layout :)
Need one of these for the trolley running in the town of my layout.
I used a 3rd diode and 100 uF capacitor to power the relay board Vin/GND pins with the same PWM voltage that goes to the P+/P- pins. Relay works fine from full power PWM (12V in my case) down to less than 1/3 full PWM. Besides not needing batteries, when I stop the train (i.e. 0V PWM), I don't hear the relay clicking.
This is the info I've been looking for. Not sure why it's not more easily accessible. Thank you so much. I assume this will work with Z scale, too? The 9v power source for the relay board has no influence on the track power, right? As long as I have the appropriate power to the rails I should be fine? Thanks!
I'm excited because I ordered this from you and it's on its way to me now. I'm using Kato N Scale track, is that OK or do I need to find a way to use the track sections you send?
Love the clarity of the instructions. Been looking for this for quite some time. Where can I find this kit for purchase? (I'm an N-scaler)
I’m having a difficult time understanding the programming. I can’t seem to “clear “ the board to start over. My off time is ok. However my run time is only about 5 seconds. And I want 25 seconds.
Just what I was looking for! Can you tell me (1) will this work on a straight HO track that will be about 26 feet long, and (2) what size DC train controller would I need to make this work?
Wonderful video, Robert! Question: Is the relay simply reversing the polarity of the flow of electricity? In my train "village" set up, could I use this system for say a motor that causes a vehicle to be pulled down a road, stop, then be pulled back? The motor would be under the plywood table I have. I could use another battery to power a DC motor that pulls the car one direction and another 9 volt battery to control this relay. If this relay is simply switching polarity, the DC motor should reverse directions quite easily. Think this could work? Thanks!
Where is the website?
Robert-
Great video! Can this work with Kato Unitrak? And Kato Transformer?
