How much Wt. in an engine??

[ChiefEagles]

I use to put lead chunks in the body of my 70's/80's U36B's and GP9's.  I they have only one motor and this would help a lot.  They do have traction tires.

2 more ouces & you'll have a pound !!  I would try a few less ozs. & go from there. Add more till you get where you want it or it works real good. With 2 motors it may be ok, Let us know & see if the motors get too hot or anything !!

Thanks, John

A while ago there was some discussion about putting some weight in a loco to help with traction.  I have a Lionel RS3  with 2 motors and no traction tires.  I had em removed so the metal wheels would activate the non-derailing switch feature better.  Now I put a weight in the front & back of the engine, maybe 12-14 oz. total.  Is this too much? or OK?

Thanks
