Train Animation Help

Uncle_Gun

Hey all
So I am relatively new to proper rigging and animation in general, so I was wondering if someone could help me out.
I am using 3DS Max 2012 and I am trying to animate train wheels with the bars connecting three of them together. The wheels turn as usual, but the bars are connected a bit off set from the center. I have looked all over and can not find a clear solution to this problem. If anyone can point me in the right direction I would really appreciate it.

To clairify, this is the animation that I would like to learn:

Thanks for the reply. I am researching helpers and I can find the cylinder helper, but I'm having trouble finding anything on a spline helper.I assume they are referring to a dummy helper, but I would really appreciate some clarification.

Thanks

I would post your questions there, since Don and Tim are both great about responding.
