Title: Re: Dummy unit horn question
Post by: TrainLarry on April 20, 2014, 11:29:21 am

According to the service manual http://www.lionel.com/media/supplements/Supplement1to9/1Complete.pdf, page 108, there is no light in the unit. If you get a hum in the speaker, try reversing your transformer connections at the track and see if that works. If that does not work, then the board may need to be replaced.

Title: Dummy unit horn question
Post by: JT828 on April 18, 2014, 07:21:07 pm

I just received a dummy unit for my sons train set. The set is a union pacific from 1975. The dummy unit looks great and the horn works, but the speaker has a noticeable hum/buzz when running the set. Is there something that can be done to reduce this? The dummy unit is number 6-8573 , u36b. I have not been able to find much information on the unit. I also was wondering if it is supposed to have working lights. The only description I found for it didn't mention lights. Thanks for any help
