running new lionel engines on dc voltage

[Model A]

Hi guys

 I would to up grade my fleet . I run conventional . I now have engine from the 1960's with old type motors .I have remover the E units and installed bridge rectifiers so they can run on dc voltage . I have recived a new lionel docksider and it willnot run on dc voltage it could damage the circuit board could i install 3or four bridge rectifiers . So don't burn up the can motor I would like to run this engine on my layout                            thankyou Model A

Are you putting AC voltage on the track and rectifying it in the locomotive?  Or are you putting DC voltage on the track?  If the latter, are you using the polarity of the track voltage to control direction?  How do you know that DC will damage the new locomotive?  Did Lionel say that?

That wasn't necessary unless you wanted to reverse the engines by switching track polarity.  All 1960's Lionels run fine on DC from the factory, even reversing as designed.

The new conventional engines work fine on AC or DC.  The first thing that happens on the circuit boards is on-board rectification of the AC anyway, so the rectifiers you propose would be overly re-redundant.

You will need to disconnect whistles & bells, however.  They will sound continuously and/or sporadically as you power up & power down & change polarity.  This goes for any era Lionel equipment.

Oh, and "overly re-redundant" is intentional wording, by the way.  I know it's overly re-redundant.

 HI BOb

I was hoping you would reply . I am running dc to the track with rectifer and also some  in the engine to switch direction  the train directions say not to run engine on dc voltage it could damage the electronics
