thank you too!

thats a giant layout you had there. i like it!

thank you guys!

looks good! id try to find a way to angle the area below the cab aswell. but other than that good work!

thank you!

now i tested it with switch tracks and i found out what i already thought: the thing doesnt clear the wheelguides of the switch! well after some thinking the fix wasnt too hard. i changed the frame that holds the bottom together to be ontop of the motor instead of on the bottom like it was. this change also included the addition of a methode of coupling a wagon to the breuer with the round black 1x1 plates holding a 1x3 plate that attaches to the single stud ontop of a magnetic coupler. the cab required some changes aswell to fit the new base but these where more subtle. i reduced the distance between the side parts and the cab to 1 plate to fit the cab being one plate lower now (it is actually held on now instead of laying on the base by gravity!) and i removed the black pieces in the middle because that is a part of the base now. the models files can be found in the link in my signature under the filename "rangiertraktor motor v2".

thank you! there is a little bit of space in the cab but it wont be easy.

now i have an update for you guys. what is better than a small lego train model? a motorized lego train model! this uses a modified cheap "tower pro sg90" servo as its motor. the servo has been modified in such a way that it basically works like a normal brushed dc motor. i have removed the servo control board and the stops preventing the servo from rotating more than 180 degree. there are several tutorials available online on how to do this. the second modification the servo got was removing the mounting points of it at the top to make it smaller. the servo fits into the model like this: the drivetrain consists of a small white lego rubber band which drives one of the trainwheels directly (no need for gearing down as the servo has internal gearing already which is sufficient). the second pulley is one of the servos attachments just with the arms cutoff and made flush with the rest of the center hub). here is the whole thing complete with the drivers cab: i changed some of the details due to my parts library and space constraints with the taller base but overall it is the same model just different colors (it is a very old unit so a bit of rust is also present ). the drivers cab just fits loosley onto the model as the servo doesnt really fit into the lego geometry height wise and i didnt want to make the model any taller so thats how it is. it fits quite snugly though so no problem there. and finally there is a video so you guys can see it running: https://www.flickr.com/photos/145736297@N05/52187870612/in/dateposted-public/ hope you like this upgrade and as always the models files can be found in the link in my signature for anyone wishing to recreate this little model.

i mean they have shown off some gbcs on their website in the past but nothing major

nice! in terms of differeces you use plastic rails now instead of the 9v metal ones

now it is time for another history lesson: after the locomotive i showed you before the siemens company built a fully electric mining locomotive that was used in a coal mine to demonstrate the use of electrical traction in a high stress industrial enviroment. enough talking here is a photo of the prototype: as you can see it is very similar to the locomotive that siemens used at the "gewerbeausstellung". the only real difference besides the size and drivers position is the fact that this one used overhead powerrails as the source of electricity. this can be seen by the cables going into the locomotive. for a better view here is a picture that depicts the loco in operation: in the picture the loco still has panels that cover the locos inner workings here is the model of the loco without covers: i tried recreating the picture as best as i could. ofcourse it being black and white didnt help. here it is with the covers on. i dont know the color that they used but from pictures of the museum piece there is a green-ish color visible. hope you like yet another history lesson

ofcourse i dindnt bother optimizing the price. if i would buy it for real i would look to get the bricks cheaper ofcourse. was just a rough estimate. anyways here is another build from me. this time it is the testing facility from a company called "SpinLaunch". they attempt to make launching payloads into space cheaper by flinging it using a giant arm that rotates inside of a vaccuum chamber. this poses many challenges especially on the bearing that holds the arm to handle the ginormous g-forces involved when the payload is released from the arm. if you want to see how it should work in a concept watch this: here is the actual suborbital test that they conducted: ...and here is my mils module. it is not 100% accurate i took some creative liberties: as you can see there is currently a test being conducted. this depicts exactly the moment when the test payload leaves the "barrel" of the launcher. here is an inside look into the control container: the container is actually two 6-wide containers that would fit on for example the mearsk train put together to have more space for an interior. the interior is largely dominated by a giant screen as any modern space launching facility should have. on the other side that you cant see there is just another desk/workbench but no screen. the building also includes two dishes to monitor the test payload as it travels through the atmosphere. hope you like this model and my explanation!

wasnt there a new york subway station that got closed because of the fact that the platforms where in a curve and trains got longer thus creating Dangerous gaps between the platforms and the doors.

looks nice! good work!

i think someone posted a video on youtube on how he repaired a broken 9v motor by using a pf train motor as a sacrificial unit. it should work the same with the pup train motor.

while not strictly 4 wide it is still interesting. one of the first ever electric locomotives. it was produced by siemens & halske (now just siemens) and was as i stated previously one of the first elektric locomotives. it was run on the gewerbeausstellung 1879 in berlin to demonstrate the use of electric traction in locomotives. it carried three cars with 6 passengers each and got its electricity from two flat iron bars (insulated from the rails ofcourse) with a voltage of 150v. the locomotive was built around the electric motors (you can see the windings outside of the locomotive). picture of the original during the exibition: now in a museum (not sure if it is the original or a rebuild): now onto the model: the wagons where not easy to build with their organic round form. the locomotive was a lot easier to build as it is quite boxy with few round shapes. hope you like the model and the backstroy to it. some people did the first practical steam engine, the rocket and i felt i needed to do the same just with the electric locomotive.

no problem. but on the other hand when you see what some people spend on other hobbies or fancy meals/drinks and stuff...

ok so lets start with the pricing @Toastie: estimated price: 324,68€ estimated price: 287,14€ estimated price: 158,31€ estimated price: 82,88€ estimated price: 884,49€ estimated price: 84,99€ estimated price: 202,71€ estimated price: 196,53€ total current price: 2221,73€ not cheap at all. my car probably costs less. in reality it only costed me the electricity to run my laptop but if you want to build it irl it costs that much. as far as estimating the cost goes i design these using stud.io 2.0 so i can just upload them as a bricklink wanted list thus gaining me info about the price on what each one would cost.

looks so good! works just like the "real" thing

love it both the trucks and the forklifts.

another one! this time a datacenter: it feaures a security fence, big sign, cooling units on the roof and much more! ground floor includes a goods lift, entrance for a truck to deliver hardware and a diesel generator to power the datacenter incase the city power goes out. second floor includes an opening for the goods lift and all the servers which are connected by overhead cable trusses. hope you like it!

looks very nice!

looks very nice! i like the yellow 3d printed cab piece more than the black one which you did before.

nicely done! especially like the loco with the brick built stripes.

thank you!
