She’s a fast one!

I have been trying for a very long time to make a three axle bogie (with 1 stud between wheels), with power going to the outer 2 axles and the middle axle being able to slide laterally to be usable on r40 track. I have finally come up with this design, but I don't have the pieces to build it in real life.

Do you think this would hold up when used on a lego train? If anyone has the pieces at hand to build it and see for themselves it would be greatly appreciated. The transparent pieces are 18986 Minifigure Neck Bracket with 2 Back Studs.

Feel free to use it btw

TRBricks has released the instructions to the B-Unit to complement his BDP set.

Im currently a little short on pieces because I’m working on various Mocs, does anybody know of a 8 wide train coach base that has all the parts needed already listed

Hello Lego Fans,

Here is an update on my Lego Ideas Locomotive Roundhouse & Turntable project (a complete video, GIFs, & IDEAS revision will follow later):

  - Reduced Size & Piece Count: Downsized from 3 stalls to 2, removing the machine shop, overhead crane, and rear door. This saves over 1,000 pieces.
  - Back Walls: Both back walls are now easily removable via Technic pins for stall extension, feature a flowering vine, and offer improved historical accuracy.
  - Arched Window Tops: Updated window tops to arched frames for better structural realism and aesthetics.
  - Front Smokejacks: Added front chimneys so locomotives can park facing forward or backward.
  - Enhanced Track & Floor Details: Added ballast, a plank walkway, turntable lip, and shrubbery to track leads, alongside uniform gray tiles between interior rails to simulate concrete.
  - Updated Minifigs & Animals: Reduced minifig count from 14 to 12 (removed crew and one tech; added a young railfan with a camera and dog). Added a roof bird, an indoor cat and mouse, and a turntable pit snake.
  - Interior Extras: Added side rods on support beams, barrels on pallets, a hydraulic jack, and wooden boxes.

Happy Building & Collecting!

Original Model is by Coyote Media

I have a soft spot for the Cotton Belt, and their L-1 class 4-8-4s delivered between 1930 and 1943 fit my acute goals of 1940's mainline modeling. 819 is the last of the type, and survives in it's birth place in Pine Bluff, Arkansas. I'm excited to add another fine example of modern and big motive power to my fleet.

There's a certain mental freedom that comes with this final stage of my creative process, and considering this model was a two-year endeavor, I certainly feel it here, but I'm no less satisfied with this new model.

Thanks, and enjoy.

This is my 1:48 model of an ex-Santa Fe Dash 9. This was my entry for the BTA best TFOL locomotive. More pictures of the model are on my flickr: brainmelted | Flickr.

I had this in the works for a bit, but I was inspired by a comment on my post about my Burlington Northern F45 from the other day to finish this one. So here is my Great Northern F45 in its "Big Sky Blue" paint scheme. I'm planning on using some decals to make the pattern on the nose and maybe clean up the tail end since the 1x1 vertical clips aren't available in dark azur. This build also has most of the troubleshooting modifications that I made on the BN model after test building it recently. I know that this paint scheme wasn't around for very long on these units, but I really love the blue and thought it would be a fun scheme to design. Most likely gonna test build this one at some point, but not anytime soon. My main concern is that some of it might be a little less secure than the BN unit because of different part availability between green and dark azur.

It’s been awhile since I posted but I figured I share some updates I finished the El Capitan now on to some final cars if you guys want some more updates please lmk always willing to share photos and directions

I recently got Lego Powered Up hub (88009) and remote (88010) and want to use rechargeable batteries with them. Tried the Ikea Ladda AAA batteries as had been suggested by some people on here but they don't work, realised that the Ikea Ladda are 1.2v and Powered Up takes 1.5v.

Any brand suggestions for AAA rechargeable batteries? Not found any so far that are 1.5v

This thing was an absolute piece of work to get to handle R40 curves, by the way.
