That looks really nice. I'm also wondering what 3-wide wheels look like. Any plans to put it on some track, and if so, how?

That's a really cool setup. Quite expensive to set up if you don't have that stuff laying around, I guess.

Excellent explanation video and an awesome track!

What about a rollercoaster, or a vertical /sloped curve?

The more I look at this loco, the better it gets. Really nice work!

This seems to provide a lead on removing stripes. On your own risk of course. http://www.eurobricks.com/forum/index.php?showtopic=79119

The issue had been discussed before: How to convert the 10133 BNSF to power functions. In this topic, a solution with stickers was used: http://www.eurobricks.com/forum/index.php?showtopic=63069 I wanted to find a brick-based solution, where I permitted myself to find a non-lego solution for the battery pack. I've succeeded in converting my recently aquired BNSF to power functions, by using two custom battery holders for 3 AAA batteries, that fit nicely into a 2-stud wide gap. Second, I filled up the cab with the IR receiver, and had to be a bit creative to get the hood back on. Third (and most expensive!), I ordered alternative grey side decorations for the power functions motor.

Looks really nice, especially in video where you can see it moving. Makes it come alive.

I extended to a 3 cars, and now I have some more decent containers in real bricks. Picture quality is not very good though.

Really nice train. If your son it too young, but likes to build MOC's with you, I suggest you build it together based on rendered pictures. Then, you select the bricks that need to be build, and he can figure out where to place it. That works with my 6-year old, and he's enjoying building that a lot.

Really stunning building and details. And a cheese slope used as cheese, nice

Very nicely done moc. Lots of details that must have taken a long time to figure out.

What about a double decker passenger train? Just google image "double decker train"

I use POV-Ray for the rendering. Here's a POV-Ray render of them together: Putting 2 and 2 together made me find a bug in the SD70M design: I had accidently offsetted the magnets by 1 plate. And here it is, the LDD file: http://www.brickshelf.com/gallery/ronenson/SD70M/sd70m_v8.lxf

Really nice how you add that third wheel to the PF motor. Simple to implement, but I actually forgot all about that hole in the middle. Nice compact build!

Thanks. This is the rolling stock to go with it: http://www.eurobricks.com/forum/index.php?showtopic=82085

Sure, no problem. The first car contains the containers I designed, but don't have yet in real life, the second of course the standard containers that come with the 7939

Nice. It's fun to see everyone adding their own twist to modding the TTX's

Glad I could be of inspiration. I've actually designed it such that the wheels can actually turn without issues. You might want to check out the LDD file, which shows better how it works: http://www.brickshelf.com/gallery/ronenson/ttxintermodal/intermodal_ttx_7939_size_v3.lxf It does slightly bend indeed, but that's fixed when you add the containers to it. I've already build it, but haven't taken pictures yet, mostly because I'm not satisfied with the containers.

I could also fit two of these in the train, especially now that it's 4 studs longer: http://www.reichelt.nl/Battery-Holders-for-Type-AAA/HALTER-3XAAAK/3//index.html?ACTION=3&GROUPID=4256&ARTICLE=113156&SHOW=1&START=0&OFFSET=16& That will give it at least the same battery capacity as the official battery holder. About 2 vs 3 axle trucks: I found this nice article that I'll read through: http://www.eurobricks.com/forum/index.php?showtopic=57085 For now, I'll stick with 2-axle, but I might get inspired by the topic to change it. I'll just let it simmer for some time before I'll start ordering from bricklink.

Thanks for the feedback. I'm not very keen on absolute scale, I'm more concerned about the relative size with respect to other lego train models. Calculating the relative size with respect to the Maersk train (an SD40M), I came to the conclusion that I need to extend it by only 4 studs, which I just did. The result does look a lot better than the pictures above. As far as the battery goes, I plan to use a simple 9v block battery: http://en.wikipedia.org/wiki/Nine-volt_battery I'll probably use a rechargable for that. Capacities vary depending on the brand and type of battery. I could also consider trying to squeeze in 6 AA or 6 AAA batteries, but that's more of a hassle I guess.

Since I had been designing the TTX Intermodal cars for 7939 containers, I needed a freight train to go with it. I've been working on this for over a month, and I'm very happy with the results. I'm especially proud of the brick-build red Z-stripe. In real-life, the flextube would be shorter of course (couldn't cut it off in LDD). There's one big issue that I welcome help for: the main train window is only available in old grey, and not in the bluish grey. Any ideas on how to overcome this? Power functions are build in, where I made the assumption that I'll use a 9V block battery, which fits inside. The standard battery box for PF wouldn't fit. The cabine roof lifts off and seats a driver. The original post was edited to reflect the updated design based on the comments below. The original design was shorter:

Nice train!

I've been looking at the 10170 TTX intermodal cars for some time, and I really like them, except the container size. When I went looking around, I found the following topic, which was a good start for me: http://www.eurobricks.com/forum/index.php?showtopic=71804&hl=10170 I however thought the design was a bit too long, to wide and too high. I ended up with only copying the elements of the 10170, got rid of the 7939 container car elements, and this is the result: It can take a double stack of containers, and with the increase of the bridge of the 7937 by one brick, it can pass underneath it.

Thanks, I re-read RailBricks on this, and it is a neat solution. Incorporating 9v motors in my design however wouldn't really work: they're a bit too expensive and I would need one for every train. I like the infrared idea, I'll let that one settle in for some time.
