I recently discovered my father's Lionel train which I believe is from 1947 or '48. I had the engine cleaned and it runs well; however the transformer (RW 110volts) does not work like it should. The short circuit light does not work--it's a new bulb, and the transformer does not stop the train! So, if anyone here can recommend a reliable transformer (it doesn't have to be original from the time ),please let me know. I'd like to set it up for him so he can enjoy it (he is 86 years old!). Is $50.00 for a used transformer for this train reasonable to spend? Many thanks!!
If the transformer works ok otherwise, you could just attach an automotive in-line fuse holder to the center rail terminal and put a 5A fuse in it for about $5. You'd have to replace the fuse with every short, but it would get you running in the meantime and a pack of fuses is cheap.
Any current production AC transformer will work just fine with that 1666.
I'd say $50 is reasonable if it works, but it also depends on what transformer it is and when it was made. Any idea of make and model? Let us know if you can.
This is a guide to post-war Lionel tranformers. If you find the one you're considering I can give you a "ball park" figure of the book value.

And aboard!
It takes 5-25 seconds for a properly functioning RW transformer to trip the overload lamp at 15 amps into a .2 ohm load. Your transformer may be fine, you may not be waiting long enough... which is fine - the breaker is to protect the transformer. As long as it is otherwise working well, you are good to go.

Thank you Flintrock76!
The current transformer is a Lionel RW Multi Control Trainmaster Transformer (110 watts) (with a whistle and reverse button). The control function does not stop or increase the speed of the train. Their is a metal slide on the train itself but it seems not to do anything?
The train is a 1666 027--1947 or 1948. Their is a wiring scheme on the back of the transformer which I believe U-A is the correct set up for train only?
Thank you again!
I cannot see how a short circuit at the track can fail to stop the train, much less fail to trip the circuit breaker. How do you have the track connected to the transformer? Terminal U of the RX should go to the center rail. Either A or B should go to the outside rails, depending on what voltage range your train needs.

Hello Bob,
Thank you for responding. The transformer works, meaning, it powers the train. However, when I turn the black switch down the locomotive keeps on moving around the track. There is also a metal slider on top of the locomotive--not sure of what it's function is.
I'm a complete ignoramus when it comes to this so apologies in advance if I'm unable to clearly explain what I mean. I am learning more and more as I peruse this site and I'm finding model trains more and more fascinating!
The 'metal slider' is a "lock-out" switch for the locomotive's reversing unit. Flipped one way, every time power is introduced, the reversing unit will trip. It has a cycle, each time the power is introduced it will flip one position. These positions are "Forward", "Neutral (not going anywhere)", and "Reverse". It cycles like this: Forward-Neutral-Reverse-Neutral. When the switch is flipped the other way, the reversing unit will not activate, and will remain set to whichever position it was in when you flipped the switch to the "off" position. Over time, these reverse units can develop issues and no longer function correctly. The most common issues are that they get stuck, and do not change position, or contacts inside of them get worn out. Sometimes a component inside them, the contact drum, can melt or warp or develop more mild damages that will cause the unit to stop working correctly.All that to say, it has nothing to do with the train's speed control.The issue you descibe makes it sound like you accidentally wired the train to a "constant voltage" output on the transformer. A constant voltage output is normally used for accessories such as lighted buildings or railroad crossing signals. As the name suggests, it supplies a constant voltage. When the transformer is plugged in, it will supply power continuously. It is completely independant to the variable voltage output (which is controlled by the handle on the transformer).I would carefully examine the back of the transformer where your wires are connected, and make sure you have used the correct terminals for the track power.Hope this helps!-Ellie

That helps more than I can express! I have ordered an instruction manual to help properly set up this system. Kids really needed an understanding of electronics back in the day. I sort of lament the loss of that required curiousity
ADCX Rob--that's great info which I copied and printed. Once I get a more modern transformer I will test it out. The train is built so well (heavy and substantial) I am extra careful with it.
THank you!
