It's taken a few months to make much progress on the level crossing. I made some gates but hit a problem as I tried to mount them on the stepper motors but needed to make them removable. This meant that there was a bit of slop introduced and that allowed the dreaded backlash to rear its ugly head. It took sometime to adapt the code to deal with this as I had to make the stepper motors 'take up the slack' every time the gates change direction.

Here is a little video.
