Hi technic builders,

today I had saw two awesome elevated monorail videos on youtube. There are not by me but I think that they are really cool and the second is funny too. Are there other cool elevated monorails moc's at the web? Did somebody know how to build automatic sliding doors?

had nobody an idea how sliding doors are possible with lego?

There are several other monorails out there, although I've only seen one other suspended monorail. A friend of mine has built several monorails with 2x2 brick built track.

Sliding doors are very possible with LEGO and aren't that difficult to build. On most LEGO trains I've seen, there is an extra motor mounted somewhere inside the train to open/close the doors.

A few more videos:

Unfortunately, I have not seen instructions on how to make motorized train doors. That is probably something you will have to figure out, but hopefully the videos above will help.

Thank you! I think the videos will help me already times a little.

I'm once again to this topic. Are there some pictures about how to build a slidingdoor like the mechanism at the PF suspended monorail at my first post? It seems this works such as supermarket slidingdoor or such as in lifts But how four doors at the same time?

Here is a page i found long ago with some hints for designing sliding doors. http://www.engineeringwithabs.ch/sdoors.htm It is only one door not motorized but make 2 of them and connect a gear rack to each one and you should have something like in the video.

Sariel likes making several elevated monorails -- see this webpage.

I had used one m-motor, small linear actuators, gears and universal joint.
