thanks for the offer, the only bits i am missing is the old style train track, I have plenty of the 9V style but not the separate rails and it looks like i will need a fair few. Do you also need the connector plates or do the old rails snap onto regular plates

We use 1x4 plates to link the track pieces together and 2x8 plates to click them in on their side. like in this image

So no, you don't need the connector plates, only if you want to make plat curves

Might anybody be interested in how it works.. here is a vid and image that shows the hook that every car has a little better

Brilliant! Love the video.

Amazing.

I wonder though, aren't the cars moving too fast through the looping? The speed just seems odd to me. Have you tried a larger loop or lower hill?

We did test heights, but only with 1 car. This height seemed to be just right, but the curve also gives it some extra speed.. so yeah, you might be right, could be a little lower probably (but not much lower)

Working on a new type of LEGO roller coaster, here's a quick glimpse

The new type looks really cool, keep up the great work!

Looks interesting!

That is so awesome
