after having thinkered around with the switch a bit more today, i realized that turning the single connecting track around resulted in tighter Clearances so i did that (irl its brick on brick contact, in Studio its hard to align it perfectly) i also improved another switch: the one in my Monorail to switch directions. it used a very fragile mess of multiple contacts, i have reduced the contacts to just the one layer again. it now uses two bc639 transistors to emulate the other layer electronically video: https://flic.kr/p/2qzWmdf schematic:

wasnt there a coaster thread a while back, try using the forums search for rollercoaster

hi, today i have built a monorail beam replacement style Y switch. of course very much a prototype, it works, and is small enough to not look weird with my 4-wide monorail. take a look: the transition between moveable switch and fixed rail was kinda tricky to get right to allow the pieces to slide past each other, but i got it to work after several tries with different slope pieces. the whole thing in the middle slides to connect either the right hand side or the left hand side to the curve here is a render that looks less colorful and cobbled together, stud.io file is in the link in my signature as always.

thank you! wanted to keep it all lego

well thats only the partial truth unfortunately, unlike our other widely used emu train, the desiro HC, the front cars are actually "locomotives", they have to run with both pantographs up, because there is no HV connection between the two, but they can only be used in 4 or 6 car sets (multiple ones can be coupled together though), like an emu. afaik they can change the number of cars more easily than a true emu. the middle cars also dont contain any traction motors or other equipment needed for movement. as for holding the window in, yes it might be possible to hold it in maybe from the top with a brick modified, the windows space isnt a standart brick width at all. @idlemarvel

ah a fellow 6 wide builder, its awesome how much detail you can do at this size. 8 wide feels like cheating to me and also doesnt really fit my layout at home, so 6 wide it is.

basically you play 4d ches, if a part doesnt work in one orientation it might work in another. as for how to get the pieces right sometimes it helps to see if other people have built something similar to what you want and go from there, not completely copying them, but just looking at building techniques, @HoMas books are a good starting point, or just look around, everyone likes to build things differently, and has their own style. one thing to be aware of is that no one is born a master of building, it takes time to develop your skills and your own technique, so dont be ashamed of yourself if the builds dont look like the ones here.

Hey guys, after a long time of not posting anything due to lack of time (college), i present to you the twindexx emu passenger train. these are widely used in germany and are the successors to the locomotive pulled double decker regional trains. they accelerate very fast, are quiet and nice and bright inside, all things the old ones are not. i use these daily to get to college, and no one else has done a model of the emu variant, there is a bluebricks one of the locomotive pulled intercity version but that doesnt look that good tbh, and isnt the emu version. at first i made a model of the middle car, because it was easier to go from middle to end car than to do the reverse, the design is inspired by @HoMas regionalexpress, and by the bluebrixx one for the top part, but with my own ideas sprinkled in. and this is the finished version, the front wasnt easy to get right, its very round, and organic, and thats not very easy to get right in lego this is the front in more detail, the window is just held in by the other parts, its not attached to the model, neither are the reverse parts of the headlights. Hope you like this model!

nice! checked it out, always awesome how you fit so much in that space while not looking cluttered.

this is so cute! i love it!

nice to see other people also using the diy 9v slot car brush system! i too use it, works very well.

chemistry beyond what i need for my EE courses has always been black magic. but to give you my very unqualified opinion here: you have captured the lab setting very well.

certainly isnt over for me...

well today its time...i had tried and failed to make the battery powered approach work with using the pf v1 Receiver. i just couldnt find a way to get it to power it. the batteries just couldnt heck powering the thing. so now i present you what is quite possibly the smallest track powered vehicle there is in lego form: https://flic.kr/p/2px6GXv the underside: and yes, despite its small size it can actually pull (in this case push but you get the idea) a quite heavy freight wagon thats a lot bigger: https://flic.kr/p/2px7Ad2

two years later...i am back at it, so now i am trying to make it all self contained. battery Situation is sorted, two coin cells are enough to power it (potentially will be changed to lipo in the future) batteries are housed here, there are custom contacts made from the legs of a resistor touching both sides. receiver is a powerfunctions v1 receiver with fried motor driver, need a mosfet driver with low enough trigger voltage to make the thing work. i have also changed the belt situation, with the previous setup the belts where falling off quite often, now each wheel gets its own belt.

looks nice!

good question, depends on placement of battery box and motors.

i did the slot car brush mod, works incredibly well (cant check with a switch, only have pf switches, need to buy some copper tape first).

time to do a metroliner remake i guess... @lifeinplastic

id assume just by the contact of the 2 pieces but not sure either.

do you need the if the switch is turned the other way the track is turned off functionality? if not here is a Tutorial (not made by myself): https://youtu.be/8stHQgi9_Yw?feature=shared

this is nice, the improvements make them fit together better.

this is it! thats what should be in the set.

if this is your first moc i am screwed. next years octrainber (if it will be a thing next year) will be very tough (assuming you also participate). but either way, very nice moc.

looks nice. one thing you could improve is the rear parts, make the roof 6 wide but keep the section under it 5 wide or make that slightly wider. like 5 wide and one plate or something.
