Update: So after just over a week of work, I have begun to build the body around the motors. However, I realized that I didn't take into account the length of the motor cables for the forward motor. Would it be a good idea to move both motors inward one stud? I'm currently leaning toward that option. Doing so would also eliminate the 1x7 technic lift arms from the design. Hypothetically, if I were to drop down from two motors to one, would the Hudson still be able to pull at least five coaches at a reasonable speed?

Current progress on my J3a for the day. I have the drive train figured out, so my next step is to mount the motors more sturdily, and then build the rest of the engine around the motors. Before that, I intend to attach the front and read trucks to the main locomotive frame. Also wanted feedback on the rear trailing bogie. Is this a good design or should I modify it?

Thank you for the feedback. Those technic beams are stand-ins for a 13 L side rod I intend to acquire when I eventually build the J3a with actual bricks. The technic beams are tolerable, but they just don’t look the proper part for steam locomotive builds.

Here is a photo of what I have so far. It is from a discord server I am in that is dedicated to LEGO train building.

Thank you for the reply, zephyr. I have not yet built the cars just yet, but I do have the parts for the observation car. You have provided an excellent guide, and I thank you for that. I intend to use it during my development of future train mocs. I haven't tried to build the drive train IRL yet because I don't have the parts for it, (especially the wheels) but I hope to soon. I do intend to post photos and ask questions if I run into trouble, but when I tried to post a photo of one of my mocs in another thread a few weeks back, I could not upload it because of the file size limit. I know this forum is not an image hosting website, but I'll have to find a way to lower their size below 100 kg so I can post them. Thank you again for your assistance.

Hello everyone, I am currently designing a LEGO model of a New York Central J3a streamlined Hudson. It will use Brick Train Depot 3D-printed XXL disk drivers, and I intend to power it with two Power Functions L Motors connected to the center axle. Where I am getting stuck is 1: How to mount the motors inside the boiler, and 2: how to make the locomotive fast and powerful, strong enough to pull at least 5 coaches. (Specifically, the ones that Anthony Sava has for sale on the Brick Train Depot website, that are equipped with roller bearings. I bought them some time ago, and I wanted to make a Hudson to go with them. I'm pretty new to designing and building my own LEGO locomotives from scratch. I've made a few smaller engines before, but nothing this large with this motor set up before, Any assistance or advice you can provide will be much appreciated. Thank you.

Quick question: is there a way to add the Big Ben Bricks or Brick Train Depot wheel files in LDD? Three of them were added to LDD when I got the files installed, but none of the others are present.

Absolutely wonderful moc! It is incredibly detailed. Are you willing to provide any advice when it comes to building articulated locomotives out of LEGO? I plan on building at least two, myself.

You don't see too many railroad inspection vehicles built in LEGO. Great work! Looks really cool!

Wonderful little shunter! I love how you were able to pull off the rear windows with those bracket plates. The light blue color looks good as well!

Thanks for the reply, Suenkachun. Everything is in working order now, but I'll be sure to keep an eye on both threads.

Here you go, this is the one I followed.

Thank you, Damian! I'm glad to be here. I took a look at your Rebrickable page, and you have some pretty cool stuff there!

Testing... 1, 2, 1, 2

Hello everyone, I'm glad to be here, and I look forward to meeting all of you, as well as sharing my own LEGO creations, which include steam locomotives, and historical warships and other vessels. I can't wait to meet all of you! Sincerely, LMGbros 772.

Hey guys, new member here. I've been trying to install these custom parts for a few days now, and they just don't appear. I've been trying to follow the steps exactly as they are stated in the LDD New Parts thread. I don't know if it's an issue of not having something or someTHINGS in the right folder or folders, or some other problems, but I am genuinely at a loss and I don't know what to do. As I said, I followed all the steps just as they were stated. Any help you can give is greatly appreciated. EDIT: nevermind, I got them installed. I followed a tutorial I found on YouTube.
