I recently acquired two Marx transformers with a 999 locomotive freight set and a (1964?) stream line locomotive freight set. Both are 50 watt transformers. The older one (I assume) is model number 1229 with no reset button. The second newer one (I assume) is model number 1249 with a red reset button. Aside from a few minor scratches, they both look pretty good for their age (cords are in tact, coating is good, etc.). However, I have read where these Marx transformers do not have the kind of circuit breaker protection found with Lionel equipment with a warning not to let them get hot. I haven't plugged in either one until I get some good advice. So, any advice would be greatly appreciated. Thanks!
The 1249 has a circuit breaker, the 1229 does not. You should use an external 3 amp automotive circuit breaker (or a fuse) to protect them both if you decide to use them. Hook the circuit breaker in series with the wire that goes to the center rail.

Thanks Larry. That's the kind of info I need!
Or if you want to keep it all Marx they made several external circuit breakers for their transfomers. Some don't work anymore so you would want to test it with a direct short to make sure it works.

I really would like to use these transformers instead of just displaying them. Thanks again for the info.
I would use one to power my lights and accessories, and the other to power my switches.
Good idea! That should keep the voltage requirements lower than using them to run trains. Thanks!
fifedog I would use one to power my lights and accessories, and the other to power my switches.
Fife always has good practical ideas and if you connect just the layout lights to one transformer you will be able to brighten and dim the lights in your buildings, streets, etc. Your bulbs will last longer, too.

Excellent! I did that with my N scale railroad. (Using a dedicated transformer for the accessory bus wire.)
