[WIP] Lego monorails. [Custom Rail Systems (CRS)]

Recommended Posts

Cleary on top, not teethed I'd say. No teeth on the inside of the straight beams, and it speeds up on those straights.

a little update from my side concerning my monorail. i have made a stopping/reversing lever just like the original lego monorail. the reversing doesnt work right now as i have yet to find an efficient enough motor driver that is able to switch the direction of the motor without too much energy loss. the switch type is a single pole dual throw type switch so i need something that can switch the other pole thus creating the need for a motor driver. currently the monorail can only be stopped/ go forward with this mechanism.

the second thing i did was improving my curve design. i made it a bit sturdier. it isnt as stable as masao hidakas original curve design but allows for more variations in the bricks used.

Seeing all of these photos make me question why LEGO hasn't tried their hands at making a new monorail system. The old ones sell for an arm and a leg, and there are multiple themes that could use them. I would pay a solid amount of money if they ever make a Jurassic World Monorail Set.

Terrific job! The PUP components are so neatly integrated. How difficult is it to change the batteries in the hub?

i now made a smaller radius curve:

smaller radius

 

as you can see in this comparison the curve is smaller. it uses liftarm 3 as the bottom parts and a smaller top beam for each element thus creating this radius

another update:

i have now made it possible for the monorail to reverse by converting my single pole dual throw switch to a dual pole dual throw switch thus being able to make a polarity reversing switch. it is rather fragile inside but as long as the train stays assembled it is robust. i cannot yet make the train switch direction on its own as it doesnt have enough inertia to cross over the zero point of the switch. it would need a capacitor bank made of several ceramic unpolarized capacitors to achive that. i have also made a monorail reverse switch:

it works just like the original switch from back in the day with the side bumpers being moveable by the wheel and that pushing the technic axle in the train.

the other thing i did was to lower the coupling to improve the curve handling abilities as before the train was either doing a wheelie when going motor car forward or pushing the other carridge into the ground when the motor car was pushing as the battery/switch car rides on the motor car.

this all adds up to the monorail being able to reverse, stop on its own and take curves going forward and backwards all the while being smaller than the one lego produced back in the 90s.

Absolutely fantastic! Great tracks and very nice trains as well!

Wow, there's a lot of motors and powered up behind it. :oh::sweet::thumbup:
