My previous design was flawed and was likely unable to take inclines, but here I have a few designs that should be able to:

Mostly an attempt for a Classic Space monorail. Due to the limited available pieces in trans yellow, and partly because I like it, I went with the 6931 scheme instead. I have the feeling this train is too heavy, but I'm not able to test it yet.

An attempt to a vintage monorail. I think this should be not as heavy.

Both trains use the same setup as Masao Hidaka's original Airport Shuttle rebuild, except that I went with PF instead of Powered Up.

Thank you for adopting my idea.
Great Job!
Space monorail is especially goooood!

Guys i now have developed a motor solution tnat i can make even smaller i will post pictures of it tomorrow. it involves a modded cheap chinese tower pro sg90 servo but sadly isnt the king of speed. now the only thing limiting getting smaller are those dang batteries! ;-)

here are the pictures! the servo is mounted facing down and is screwed into the drive facing crossaxle hole of the technic liftarm thin 1x3 and is facing with its output shaft down on its output shaft there is a 12 tooth bevel gear screwed in ontop of a servohorn with the horn part removed to act as a spacer. I followed the method on how to mod one of these servos but i have removed the controll board entirely and soldered two of the three wires of the servo cable directly to the motor so it is a super compact dc motor with gearbox. I made multiple variants front wheel drive like the powerfunctions one, rearwheel drive which is better Imho and mid mounted just like the original monorail system. without further ado here are the pics:

rear wheel drive:

and finaly mid mounted:

sorry that all of these are just screenshots but i really dont have a good location to take pictures. if you need the files they are here:

I assume it can go through curves as well, right! :wink:

Thank you for sharing - even with a look inside! :oh::wub_drool:

i expected nothing less from the master of monorail! in all seriousness though awesome monorail that chain drive looks insane to come up with :thumbup:

Superb work presented here :thumbup::thumbup::thumbup:

My question regarding all LEGO monorail topic: is it any chance that TLG will reintroduce monorail series (either Lego City or Space) with all that parts like monorail rail parts and motor in modern version of course (drive as powered up, enhanced rails, etc.)?

Regards

First of all thanks for the kind words!

As for lego reintroducing the monorail that is higly unlikely as they a: have the rollercoaster track system to use for that purpouse and b: have no interest in monorail whatsoever it is a niche market for them even more than trains.

I follow this thread from the early posts - it's amazing the level these monorails have reached, in terms of track and rolling stock! 

Great work, it's always amusing seeing new models and videos of these nice machines!

Ciao!

i ve got another idea on how to make tracks for the monorail:

straights are basically just 2x2 bricks stacked on top of each other and layed on its side like this:

monorail straight track

curves are made by sticking a 1x1 round or normal tile into a brick like this:

monorail curved track

and then while connecting another 2x2 on the  bottom of the one you have just placed the tile into it prevents the studs from sinking in completely on one side thus making a curve

Those are brilliant in their reliance on inexpensive parts. I suspect they would need some reinforcement to be practical though. Perhaps the 2x2 brick straights have periodic 1x2x5/6 bricks with studs on one side to lock them in to 2x plates for stiffness. As for the curves, with only a pair of studs holding them together that could be tricky. In this case, perhaps an old 4.5v curve rail could be used underneath for stiffening.

for the curves i have tested them (atleast with my very light 4 wide train and they do hold up pretty well when you dont move them but i dont know how they would handle heavier and faster trains. to reinforce the straights/add pillars you can use a pair of 1x1 lamp bricks and a 1x2 brick ontop for the running surface and then add plates underneath the beam for added stability
