(MOC) BNSF ES44AC locomotive with .lxf

Recommended Posts

Posted (edited)

My first Lego locomotive MOC. Modeled after a BNSF ES44AC locomotive. 6 studs wide, 50 studs long and powered by two Lego Power Functions train motors. The three axle bogies have enough articulation to negotiate the standard Legos curves. It's made up of about 1200 bricks, took about 50 hours to design in Lego Digital Designer, 8 hours to assemble and cost a little over $200 to build, complete with electronics, from parts purchased off Bricklink.

I've included the .lxf file below and welcome anyone to build, copy, modify or just examine my building techniques. I took great care to create many different groups to make the digital version easy to disassemble an examine.

I've also included a link to a YouTube video of  it running. It negotiates the standard Lego curves with no problems. I hope you like!

Wow!

An awesome build in 6 studs wide!  Excellent work :-)  The wheel sets move well, and it handles the curves quite well.  I'd be game to build it, but I have other projects on the back burner as it is now. I'll revisit this soon.  Again...congrats on am awesome build. The baby needs to make an appearance at a Brick show...or on LEGO Ideas...hint hint.

Thanks for this.  I'm going through trying to upload it to bricklink but for some reason several pieces aren't in their database.

You are welcome. In a big build like this it's hard to get the file over to Bricklink. You best bet is to move it over one group at a time. Create a LDD file and name it something like "ES44AC for BL". The highlight one group and then ctrl-alt-g to create a template. Then open your new "ES44AC for BL"  file in LDD and paste the template into that file. Save the file and then upload it it to BL. Then once you try to verify the parts in BL you'll get a very brief popup that says "part # xxxxx can't be found". Pop back over to your new LDD file and search for that part and delete it and save the file (make a note of the part number and quantity). Then pop over to BL, search for the part and manually add it to your wish list. Then try uploading to BL again and repeat as necessary. It will take some time and effort but EVERY part in that loco is a standard part. The problem lies with the LDD to BL conversion, not my parts choice. For example you will find that BL cannot find a standard 2x3 tile. It's a very common part, used in all sorts of sets and builds, but BL can't find it. There's only a dozen or two parts in that loco that BL can't find and breaking it down by groups makes it much easier. You can do It! 

I wish to heck BL would enable their 'share wanted list' feature that's been "coming soon" forever! It would make things so much easier on everyone.

Really a good start! It's very good and...has a great "massive" look! 

Nice video too!!! Keep up the good work! :laugh:

Thanks! I just realized I didn't include a pic of the underside so I added one in my first post.

Wow what a nice build, so great of you that you are willing to share the ldx file!

I will review it and learn from it. Hopefully I will be able to build something myself!

I'm glad this topic got bumped up:  That's a really good job modelling one of the big ol' powerhouse freight haulers used by BNSF (and other Class I railroads).  I like your rather elegant solution for how to convert the RC train motors into 3-wheeled bogies, but still have it able to negotiate the smallest radius curves LEGO track has.  But still, at 50 studs long, that thing is an absolute beast!  My biggest locomotive, the GG-2a (basically a hypothetical modernized GG-1 in Norfolk-Southern colors) is only 38 studs long....
