I can vouch for that! I can say - with great confidence - that the best job I ever had was in Legoland, Billund while I was in high school. The job: keep the outdoor small models running from 15:30 when the real engineers left, until park closes. Then leave a note about the stuff I couldn’t fix myself.

The electronics were industrial PLCs wired to a control computer, and the mechanics inside the models were made from industrial type stuff that you might see on a robot, conveyor belt or the like.

Most of the models (trains, cars, cranes etc.) were built on a metal chassis or skeleton.

Fond memories of getting paged by the system with “ALARM: Cars, Norway” to discover that a kid had dropped her soft ice on the highway ;)

Please, please, tell us more about the behind the scenes system keeping all that running.
