Rollercoaster with lift
Me and my daughter have been refining this for the last few months and have finally got it working.
We created a lift as she wanted a loop that the track then went through and we didn't have enough track. The lift gives height really efficiently.
This was our first design and other than building a screaming serpent we had never built a rollercoaster before so it took longer than expected!
We added releases for the car at the bottom and the top so all that is needed it is for it to be winched up and down by the handle.
