Space 1999 Coaster
Some "making of" pictures
First version of the elevator.

This tiny step upwards was enough to stop the train because the speed
was so slow when the train started to move from the station.
In the final version there is only a short dark blue track piece on the lowest
part of the elevator track. The step comes later and the train has then gathered
enough speed to clear the step.
There were many different versions of the elevator. After some tests I noticed
that the ideal weight difference between the elevator and the counterweight is
45 grams. That makes the elevator go down smoothly. So, with every new version
I had to weight the elevator and add or take away plates from the counterweight.

I tried to make the gap smaller this way.

| 
Bad idea. It stopped the train completely.

The first version of the rollers.

| 
The final version. These work much better.
