I feel the same about the boiler, but I had calculated the diameter based on the real one's and the scale, and the built is quite accurate. Maybe it's some optical illusion (the very long things looks thinner sometimes, and this boiler is long ;)) and regard the photos the perspective makes the 'nose' bigger. Or the later versions of the loco was built with bigger diameter boiler but it's hard to find technical infos or blueprints so I don't know :) One of the earliest version overlayed with the actual built: Don't forget to make her happy with supporting the little -almost twin- sister on ideas :D https://ideas.lego.com/projects/0719c385-2cb4-47f0-bb7f-1b902ba52c8d

I'd like to share my latest build here. I have a plan to make some of the iconic locomotives from Hungary in large scale and this is the first of them, started from the begining the stream era. The 424 series was engineered and manufactured in Hungary. 514 units had been made between 1924 and 1958. As a multi purpose engine it was used for passenger trains and hauling and later for commuter trains. Was allowed to fly with 90 km/h what was a good number at that times but the unofficial speed record is above 120 km/h. There were several modifications as the years passed and was used till the early 80s. Two working engines remained and serve as nostalgia train sometimes. The scale 1:33 was determined by the big wheels (https://www.bricklink.com/v2/catalog/catalogitem.page?P=90840#T=C&C=11). And it led to 1 stud wider gauge than the standart tracks (it's almost the G gauge). Not modelled a particular one, more like my favourite mixed version from the early era. It's a 'motorized display set' so you can observe the rods' movement if lifted with some bricks under the frame. A huge thanks to @zephyr1934 here for the custom rods and valve gear bars. All the big wheels are driven by 2 power function L motors. The battery box and the IR receiver is in the tender. Theoretically it can run on G gauge straight tracks, but I haven't had any to try sadly. I've used about 3200 parts and the model's dimensions are 73*11.2*15.6 (cm, L*W*H). Some more pic (The rendered pictures are without the pneumatic tubes as I couldn't find them in stud.io.) Some not rendered And some from the original: (the last one is with the permission of the author of the pic) And the very last: sample from the stud.io plans: Hope You like it. There are a V1 version I have submitted on ideas, but not yet approved. This version is without the smoke deflectors as on ideas max 3000 pieces are allowed, and of course without the custom rods as only official lego parts can be used. So the V1: And if there is someone who wants more I have made a secret V3 version as well :) Have a nice day!

Hi all, just want to show my first modding attempt. Motorized with 2 PF L motors and added a lego weight to improve the grip. The boiler radius increased by one plate to fit in the motors and the loco's height is now +2 plate as well. Also added +1 brick to the length. Digital only, but the parts are ordered. :) Inside:

This is a nice one, I like it very much! Supported. Details are cool, and the complexity level is optimal for an ideas entry. Good luck!

Hello The result of some Sunday afternoon designing. Just for fun and to add some cars to my rolling stock :) Tried to keep it simple and toy-like (not modelling real one). 7 wide, and exactly 500 parts.

I wish everybody Merry Christmas with the final pictures of the loco.

Thank You! Yes, it was built for the contest, I just need to take some better pictures to enter.

Finally... the original

Almost done.

------------------------------------------------------------------------------------------------------------------- We have done the test runs, and it was succesful. She can handle all the standart geometry tracks, but looks much better on r72 curves and r104 switches. Not a fast one, but there is room for impovement (there is enough room to change the M motors to L, more horsepower might bring higher speed) Waiting for the missing parts...

Heyy, it's a good idea! I tried to redesign the buffer area, but the brick built buffers seems weird. The problem is the scale. The 2*2 round tile represents about 85 cm diameter, but the real ones are way smaller. I think that brick built buffers are seem good in 9W or bigger models.

Yesss, it's a Nohab di3. These locos used to pull the holiday trains near Lake Balaton in my childhood and became an icon in Hungary. Some of them were renovated, and can be seen at Hungarian Railway Museum. There wasn't much progress (busy weekend), but the bogies are done. 199 parts each. Next step is the assembling, and doing some tests on the track.

An earlier draft. The real built is at this phase...almost.

Nice guess as the two locos are similar. Have You got a link to your design? Sooo, the bogies are ready (structurally, but I need to add some details later). There was some progress in the building also. Step 2: boat with some strange bogies :)

:) It's funny, but that is not a boat of course. But I must admit, it's ship shape thing (at first sight). I have to add some details to prove that it's a loco :)

Hello! This is my first design which modelling a real one. (to have some fun: free to guess, what was the original) Width: 7 studs and 1 plate, Length : 50 studs Drive: 2 PF m motor. (3 axle bogies, 2 driven) First step: final version (?) of the base with some details:

Hello I like to share some pictures of my new station. Still a WIP, but shaping good. Based on 80*96 studs (without the main stairs). Modular built: Consumes about 5-6000 pieces, but I am working on the inner things, so it will be more. Tomorrow I am going to take better pics in better light conditions. Till then here are some more pics in twilight mood.

I'm really happy, You (and your son, of course) like my terminal crane. It was a brick by brick built, sadly there is no any digital asset for it. I planned to make LDD file, and - it seems the time has come - I will do it. But at first I have to finish my current work:

Yes, I did. I was so excited and fully forget the rule on Ideas: only Lego parts can be used. Most sites/places the Big Ben Wheels are accepted, but on Ideas it isn't. After I realized it , contacted with the support, and asked to remove the project. I am so sad especially because she received 500 suppots in five days, so she would have made it to 10000. Very sorry...

She is on ideas now. Please support if You like ! :)

Thank You! Train projects don't receive many votes on ideas, but maybe it's worth to try. Should I try it? Opinions?

Thanks for the appreciative words, I'm very happy about! I'll try to raise the cab's roof with 1 or 2 plates. Sadly not possible to make the tender lower because of the the AA battery box (it's really big).

Hello I like to share the result of Spark Industries' new side project. The company produces modern locos and cars, but wants to salute the old times. So designed a steam engine with enthusiasm and love. She is a 4-6-4 Hudson type loco: There wasn't a particular real loco for modelling, but the main shape based on Canadian Pacific 2816 and Union Pacific 844. She looks best on bigger turning radius, but deals with the standart lego curve and switch. The built width is 7..8 studs. The loco is 54 long, and with the tender it's 83. The Big Ben Bricks' XL wheels fitted mostly for the desired scale. Some curiosity: The steam valve is a built in little pneumatic cylinder. PF cable used for pipeline imitation: The handrails on the boiler's two side made of the very old technic flex system's inner cable. Electric side: 2 PF train motor 1 PF L motor 1 PF IR receiver (v2) 1 PF battery box 1 PF extension cable (50cm) 1 PF polarity switch The tender contains all the PF elements, except the L motor and the extension cable. Two train motors are attached to one output of the IR receiver (of course, one of them with the polarity switch). The L motor is in the loco, connected to the other IR receiver out. That way, it's possibble to start the loco with full voltage, the big wheels slipping, and then turn on the main drivers in the tender. Some more pics: Hope You like it!

How much is the maximum output current ? (one/both output(s) utilized)

Thanks for the kind words, I am so happy, as all my concepts came back as comment. @LEGO Train 12 Volts yes I tried, but the rotation transfered to the other side of the cane (and the winch) by technic axles, and the longest is 32 stud. Using more axles results in a bigger center (winch) section, but I wanted to remain in city scale, so rejected this. Other option was to skip the lifting potential from the road or the green cargo area, but I wanted all two :) @Vilhelm22Sorry, it's built brick by brick, so no LDD was made. Technical details: There are 3 m motors, conected to 2 pf ir receiver (one receiver out isn't used). Each motor drive one function directly. Motor A: Moving the superstructure. After a clutch, there is a worm gear-24 tooth downgearing. It's provides enough torque to move the heavy structure, with proper slow speed. The real driver is a 8 tooth little gear conected to the long rack. The problem was the size. Driving the thing's one side was not sufficient, the driven side 'overtaken' the other, and the crane was falling... So, it was necessary to bring the driving to the other side, with one of the long axles. The two sides must be synchronous, for that the better solution was to bring the rotation with high rpm, and downgearing it on the other side too. Motor B: Moving the center section. The clutch gear drives two 24 tooth gears (1:1), so the rotation's direction and speed is the same. The two lower axles with many-many worm gears moves the center section with the help of two little racks. Motor C: After a 12:24(clutch) downgearing rotates the 4th long axle. In the center section there is an other downgearing to slower the winch's speed. It's a 8:24. Essential to use here the red 8 tooth gear, because of the sliding ability.
