Louis Marx Cat.No. 1669 Setup Help for 3 rail train track - Lionel Trains
Posted by Garage.Sale.junkie.for.trains on Sunday, August 27, 2017 3:22 PM

i have searched high and low online for a how to setup my newly acquired Lionel Trains with (I guess) a 3 rail track with a 100W, 60 cycle , Toy Transformer power source. As you can tell I am very inexperienced in this arena. 

After several hours of research and finding out that Louis Marx is no longer a viable company, the manuals are (for me) extremely hard to find. 

I purchased a dusty Lionel train set at a garage sale (my autistic son LOVES trains, Thomas the Train specifically) and I wanted to have one thing that I am knowledgeable with when he is ready for an upgrade. he is only 4 now, so I have some time.

but anyhow, this train set is set up and I am ready to educated myself on the "how in the ..." does this thing work. I don't even know if it does work.

I spent 30 dollars on the whole thing, and my wife told me I was either brilliant for the purchase or an idiot for not making him show me it works.


I tested the transformer it generates power, but hooking it up properly has my baffled.

ASSISTANCE PLEASE. My sanity depends on your expertise and willingness to share so that I can be the Superhero for my son when he is ready. (Oh yeah, show my wife "what's up")


Thank you in advance. Pictures will do me wonders.

Start HERE with Thor's Marx overview, then HERE for details on hookups & operation.

nothing to worry about, trains are easy. your track has three rails. your transformer needs to have two wires run from it to the track. you need what is called a lock on to connect the wires to the track. one wire needs to go to the center rail, and the other wire goes to one of the outside rails.
