I am looking for a solution/tutorial for animating a train along a spline.

Preferably, I would be able to build my train of any length with a library of engines and rail cars. After the train is complete, I basically want the cars to follow the engine along a spline atop the track.

I can do all of this so far...

My problem now is getting my rail cars to take the turns with the engine instead of following in a straight line. I have tried linking them and using IK to establish pin connections between the cars, but I am still not getting it right.

Max's built in user help and tutorials haven't got me out of the woods either.

I have animated a train before for a brief animation clip using dumb brute force - (path constrain car to spline, create instance, adjust % of path travel, repeat) - I want a more elegant, long term solution.

Any suggestions would be greatly appreciated!

oh, im about to do just the same thing (for the 'L' in chicago) so ill be watching this as ive never used IK.
