Don't know if I should be asking multiple thread questions in the same section, but here goes.

I purchased during the Summer via eBay a Lionel 6-16777 Cola Car, which worked perfectly, then in October an old Lionel 3462 Milk Car, which was stated as working. My plans for the 3462 Milk Car was to try my initial “kitbash” and repaint to imitate the Lionel Witches Brew Car, without spending the $150. Now the problems. The Milk Car never worked from the beginning, and then soon after the Cola Car stopped working, which lead me to believe that maybe something happened to the Operating Track. But that wasn’t the case as my Log Dump and Coal Cars worked on the same track. The cost to repair the Milk Car was more than I paid for it, so I wasn’t going to have it repaired. I didn’t bother contacting the eBay seller about the non working item and just moved on.

Either way, what would happen after the Unload button was depressed, the lights on the other accessories on the track would dim and then would hear the motor of the car buzzing but the figure would not come out. After about a week, only the lights dimmed but there was no buzzing on either of the cars. Please note that all of these attempts were done using the transformer at all voltage levels.

I gave up trying to get both cars working for the past month as I was concentrating on Christmas. So now with Christmas over, the two cars have come back to the forefront of what to do. Any ideas on what is wrong with the cars?

1. You can have magnet-operated dump cars that work fine, but do not use the auxiliary rails on the operating track.
2. The fact that your other accessories are dimming indicates that you might have either too small a power source or too much resistance in the circuit wiring.
3. Do the accessories dim when just the magnet is energized without an operating car over the track?

Operating cars with sliding shoes draw extra power since current flows simultaneously through the magnet in the track and through the solenoid inside the car.

Dale, when the "Unload" button is pressed, the magnet should not be energized.


Yes it should. The only thing that changes for a UCS between "Uncouple" and "Unload" is that the Auxiliary rails on one end of the track are connected to the center rail for "Uncouple", and to the outer rail for "Unload". "Unload" is also intended for magnet-operated cars such as dump cars and searchlight cars. (See Greenberg's 1985 edition page 638)
The third leaf down in the pile, for the magnet coil, is completely left out of the circuit for "unload" button activation by means of the plastic spacer.

The Lionel service manual is not specific in the narrative about this, except to say the electromagnet "is used to control several plunger-operated cars". The pictorial diagrams and schematics are quite clear, though.

We are both correct! I am talking about the UCS track, and that controller has the coil and two aux rails connected to the top leaf of the switch stack. You are talking about the 6019 (on the previous page in my Greenberg book) that has the coil and one aux rail connected to the third leaf. Win-Win!

The original poster of this thread didn't identify his unit.

Dale - 1) Interesting. That could be related to my 40-watt transformer that I mentioned in another thread. 2). Yes, the accessories dim whenever the magnet is energized, regardless of whether an operating car is there.

One last thing I should mention is that if the 4 wire cable is put on in reverse order, it will do like what you are experencing, but you already said your dump cars work. Try reversing the order of wires (turn the cable on the track 180 degrees) and see what happens.


Chuck - I have basically zero electrical knowledge (that scared me off from O Gauge at first) but that sounds easy enough.

Will probably work on that Friday and take all the ideas mentioned in the thread. Sorry that I didn't mention it before, but I'm using the FasTrack 6-12054 Operating Track
Thanks for the help folks.

Finally got around to it today and after everything the Cola Car is working again. Yes! The 3462, on the other hand, still just buzzes but the doors won't open. Used the throttle for the PowerMax on full to check if the lights on other accessories were dimming (I used one building) and they were. Will eventually get separate (and more) power to operate the accessories separately.

I'm not mechanically oriented, so I'll probably put it up for sale on this site or eBay for the tinkerer to have fun with.
