Lego train


Friday, September 10th, 2004

I have a model train. This is not new news.

However, the model train now has an automatic level crossing. This is new news. This is also very cool: as the train approaches, the boom gates lower. When the train has passed, the boom gates raise again.

Model train also has a manual override switch for boom gates. Flick the switch, the boom gates stay down. Release the switch, the boom gates go up… unless there’s a train coming, in which case they stay down until the train has passed. Again, very cool

Model train now also has one set of electronic points. Flick the switch, track A. Flick the switch, track B. Flick the switch… you get the idea. No more ungainly leaning over the set to change tracks… almost. I am still short a bit of cabling to connect everything up.

How is it all done? By the magic of MindStorms. Woohoo. (oh, and eBay…)
