Lionel Post war engines

[vdegrazia]

I have an "o" gauge diesel # 2032 and a steam engine #646. Both of them run well but I cannot get good traction with them. They are hard pressed to pull more that 7 or eight cars without significant wheel slippage. And this is on th flat.
I have cleaned the wheels and removed a lot of residue and the track is virtually brand new. Any suggestions? Anyone know what these engines should be able to pull?

Also, there seems to be alot of "wobble" in the drive wheels of the diesel. What should I be looking for?

Any info will be greatly appreciated.

adding weight might help



reminds me of my one Marx Streamliner, it's insanely light and only has one drive axle, i had a heck of a time getting that thing to grip


also you could coat one of the drive wheels with rubber, but don't run post war trains like yours, soo someone else here can tell you something better

Thanks for the response. Both are quite heavy being die cast engines and both have "magnatraction" so being light should not be the issue.
