Thanks Michael for the response.

I would like to progressively shift the objects, parallel to the curve at each station.

If such parallel shift would amount to the step arc length, the object would essentially just roll over the curve, as if having a flat base.

*Edit
Essentially I'm looking for a "Radial Step" functionality from Circular Array in the Curve Array. Does this addition require changes to the factory, or can it be done in java script?
