Oh then you're going to love my current project: a 12V 80's layout ;)

It's a nice day in Lego city (desert actually) and Leo decides with some friends to raid Area 51. Leo's a smart guy and calls in the help of his friend the Terminator, will they make it?

So I took a Lego train into the mountains...

@Littleworlds @zephyr1934 Thanks! -

Thanks! There was approximately 5 meters of track. Honestly, this time it was two times as crazy as the previous one ;) This time my backpack was heavier and had to walk 7 hours one way instead of 3 hours the other time :) -
I climbed to 2650m at set up a lego train in the snow. This is the result :)

This looks so much like the real thing! You totally nailed the curves, well done!

Yeah but I wanted to try something without sensors, that was the challenge... -

Like every other project of mine, it never works the first time! The problems were with the timing. -

^^Thanks, but I really do envy everyone's (train)building skills! -

Yeah well, it took me a while to make it run like it did ;) -

Thanks! And yes, all the trains are track powered. Adjusting the interval was indeed a thing, one passenger train was (a lot) faster than the other. I tried different motors to get their speed as close to each other as I could. Given that I didn't want the freight trains wait too long when a fast passenger train was passing the crossing, I decreased the clearance for a slow train as much as possible. It went wrong a few times, a nice fails video will be coming out in a few weeks. -
This rail crossing is automated by two Arduino's. One Arduino will take care of the actual crossing (making the freight trains start/stop and the signals) the other Arduino controls the passenger trains which start/stop from two different stations. Because there's only one priority track for the passenger trains on the crossing, but both stations have two tracks, the latter Arduino also has to control the direction of the passenger trains on the crossing and also flip the switches to make sure the passenger train ends up at an empty track at the station. Both Arduino's have some low level communication between them: as soon as a passenger train is started, the crossing-Arduino is told to put the lights on red and to stop the track. The crossing-Arduino has a setting that tells it for how long the lights should be red. Oh, and there's of course also the Lego Terminator. Enjoy!
