Carabande Action Set and PitchCar Extension are two remarkably similar products, but each is only compatible with its base-game, and they have differing content.
Carabande Action Set
This expansion is only compatible with Carabande (but not PitchCar).
Contains:
One hourglass-shaped chicane straightaway
One y-shaped chicane straightaway
Two 90-degree curves
One jump
Expands:
Carabande (but not PitchCar)
PitchCar L'extension & PitchCar Extension
The differences between these two products are their box and content. L'extension comes in a plain brown box with a sticker, and Extension comes in a glossy red box like the PitchCar base set. Neither of these is compatible with Carabande.
Contains:
Two straight pieces for crossroads
Four "tight" curves (with two sets of railings)
One "bottlenecking" curved rail straightaway
Two small jumps, with bridge and track piece to use as jumping-crossroad. *
* The original brown-box L'extension did not include the jumps but did include a second "bottlenecking" straightaway.
