Lionel 2349 buzzing sound

The e-unit buzz is normal.

Locking the e-unit out is the way to stop the buzzing by removing power from the coil.

The shell could possibly amplify the buzzing.

Thanks for your answer.  I feel better now. It is a very nice locomotive and runs great.

 

Funny that something happened in this model/year for these to buzz.

 

Take care,,,

Ron,

All of the old e-units buzz. That is the nature of them because of their design.

 

Larry

Well, considering these were toys...they sure are pretty cool.  I just start collecting Lionel trains about 3 years ago.  I learned a lot and like doing minor repairs.

 

plus, my wife won't let me buy the muscle car of my dreams...trains are a little cheaper.

 

Take care.

Ron

As others have said, all e-units buzz. Some are quieter than others. If the noisy annoys me, I turn off the e-unit.

Could I add this? Doncha just love the E-unit buzz accompanied with the aroma of ozone. Brings back memories of one's childhood .

You can always install a full bridge rectifier which will take out most of the buzz if not all. We would suggest at least a 4 amp.

The GP 7 and 9 just sound louder because the shell is so close to the E unit.

Guys

 

I haven't used this site (or others) much for asking questions, but everyone sure is willing to help and with very good information.

 

Just this last note...the shell is more narrow which can amplify the sound.  That makes sense...thanks.

 

Dave... what is a full bridge rectifier and where can I buy one?  As you can tell, I am not that experienced in repairing trains (or electrics) but I get a kick out of working on these trains - but I keep it to mostly minor repairs.   So, I don't really know what that rectifier is and/or how to find one.

 

Thanks

Ron

Digi-Key is one source of bridge rectifiers. Here is a 4 amp unit.

 

Larry

Yes

Ron,
A full bridge rectifier changes AC current to DC current. In most instances
it will quiet the buzzing in an electro magnet. The E unit uses an electro
magnet to shift gears so to speak.
You can get these on line or at a radio shack if yours has not closed yet.

Ron,

 

You may already be aware that the Lionel Postwar 2349 Northern Pacific is one of the most desirable Postwar Geeps.

I don't think installing a bridge rectifier will hurt its interest to a collector, so long as you don't drill any holes to install it. Any wiring modification could easily be reversed.

Just thought I'd mention this.

Of course the engine is yours to do with as you see fit.

Thanks guys...

 

I think I will leave it alone. It is in very fine condition and I don't want to mess with adding the rectifier.

 

I really appreciate everyone's help

the E Unit buzz to me isn't that bad. It's part of the charm of postwar & MPC era trains, along w/ the smell of ozone from the open frame motors, the steam whistle & buzzer horn & the smell of the smoke pellets
