Are the lionel fastrack operating track sections troublesome?  Have 3 and all 3 work about 5 percent of the time correctly.  Unloading button which is the one I desire to use 99% of the time maybe works 1 out of 50 tries.  The uncoupler seems to work most of the time.  Trying different cars yield same results.  Just acts like the unload button receives very little power most of the time then once in a while it will dump 6 logs easily.

  Took the panel off the back of the button switch and everything looks fine although very cheap looking internals at best.  Any suggestions?

With regards to the operating track section, I'm having a problem: when an MPC GG-1. When the gg1 passes over the track, the trailing truck coupler opens.  No matter which direction it's going, the trailing coupler opens. I've not tried another GG-1, basically because I have only one GG1.  This does not happen on any other engine that I have.  I'm not trying to hijack the thread, I thought it might be helpful with the subject problem.


I have the same problem with the Fastrack 6-12054.  I bought in new in 2016 and only use it every Christmas season.  Each year when I set up the track the unloading button barely works.  I've brought it in to my local Lionel dealer in 2017 and this year.  He takes apart the controller and said the the contacts on the 4 brass tabs look like they arced and don't make a good connection.  He has sanded then with emery cloth and also used a small wire wheel to clean the tabs.

The track is only used for about a month per year and the unload button is not used excessively or held down for a long time at once.

I've had the older 027 uncouple\unloading tracks and never had a problem like this

Looking inside controller it appears all 4 contacts are used to make unload function work while 3 contacts are made when button is pressed for uncouple function.   Do not really understand how all 4 wires that go from track to controller touching each other make unload function work.

I would just like to figure out how to wire unload function to aftermarket switch like a doorbell.

The FasTrack controllers are junk and the wiring is grossly inadequate.  You can substitute a DPDT center off switch of your liking for the Lionel controller and 4 conductor wire(even bell wire would be better than the original wires).

Because some operating cars work with the uncouple button(using car chassis for ground/common) and some with the unload button(isolated from the car chassis), a DPDT (on)-off-(on) switch can be used to replace the bulky controllers. 6019 illustrated, RCS/UCS, GarGraves/Ross, RealTrax, FasTrack similar. If you really don't want the magnet energizing, just don't connect it or cut the connection.

DPDT detail connections... three terminals on the left, three on the right, toggle/slide up & down, as viewed from the bottom. Sorry the numbers aren't very big.

Rob's diagram shows what you need to know but I already made this diagram for a previous thread albeit for the Realtrax operating track.  In this case MTH used a sealed standard (ON)-OFF-(ON) DPDT toggle rather than the "brass tab" style apparently used in some controllers.  I found it somewhat amusing how they fabricated custom mechanical parts to maintain the look and feel of a traditional O-gauge lever controller mechanism with a "modern" toggle switch buried within!

The WTS-6303 appears to be a Korean company with a 125V/3A rating...a functionality readily available in switches that cost, say, $2-3.

Or, to your point, separate the integrated toggle into separate doorbell-style pushbutton switches.

I know this is an old post but just to mention I took it a step further for the 6-12054 operating track and totally isolated the magnet from track power one side goes direct to accessory and the other thru the existing uncouple button and that works well with any transformer that way you just need an accessory output
