O gauge(32mm) single track level crossing base, fit code 100 rail.
Fit gates, gear wheels and control sticks to enable gates to move one at a time.
Requires single track gates, 2 gear mechanism and 2 control arms pack. Fit rail before painting, as it tends to be easier. Can be a very tight fit, so
suggest running lenth of thinner rail(code 75) through first.Slow and steady is better and safer than rushing it.
When fitting gear wheels, take it slowly, they do fit, and when in place , spin round till nice and smooth running.
