Hi Steve.

Well, actually the spline itself can accept 'clock' as the variable (if
animating, as other such animations are done) so you would just apply your
spline to each object for the motion to occur. For a train or traffic you
would need them to use offsets within one originating spline or make several
individual splines having the same path yet different starting/ending 't'
values. Probably some complex way of doing it too but that's the simple
explanation.

Take a look at splinefollow.pov, in the scenes\animations subfolder, since
it shows a good example of what you are wanting to do.
