Barduck Posted January 7, 2015 (edited) After LEGO Train 12V's 7 wide version it's time to finally post the pictures of my 8 wide version (wel, actually 10 wide on most of the roof). She's become a real beast featuring just over 2900 parts, 109 studs in length, 4 PF train motors, 2 PF recievers and 2 PF batterypacks. Recieved my lettering yesterday morning and spend the better part of the afternoon putting everything in place, hence the delay in posting the pictures of the finished MOC. So here she is: The lucky driver posing with his engine: DDA40X by Barduck12, on Flickr Building instructions of this beast have also been added to my Bricklink: http://www.bricklink...e.asp?p=Barduck For the WIP topic (and there's a vid of her running too): http://www.eurobricks.com/forum/index.php?showtopic=102228 Edited January 7, 2015 by Barduck Share this post Link to post Share on other sites
technic70s Posted January 7, 2015 Wow, that looks amazing. Nice job Barduck, I particually like the detailing on the sides of the trucks. Share this post Link to post Share on other sites
cgarison Posted January 7, 2015 Wonderful MOC. Very Nice build. I agree the detail work on the trucks is amazing. Share this post Link to post Share on other sites
bjorkan Posted January 7, 2015 Gosh, this is real train monster, but I like it :) lucky you that your HE 10233 (on YT movie) has stopped on the left side of the layout, I'm not sure it would be possible on the right side Share this post Link to post Share on other sites
LEGO Train 12 Volts Posted January 8, 2015 Huge and amazing ...another DDA40X back to life! Share this post Link to post Share on other sites
zephyr1934 Posted January 9, 2015 Wow, that thing is huge! Though that is what UP was going for when they got them in the first place. The details are top notch. If you have time, it would be neat to see a shot of how you concealed two train motors in those detailed trucks and how you made them work together. Does it do standard curves at all, or does it need wider radius? With all of the weight in that build and the long span, you clearly did a good job engineering the frame. I see no trace of any sagging. Share this post Link to post Share on other sites
Barduck Posted January 9, 2015 (edited) I'll try to post some extra pictures of the underside of the trucks in the weekend. For the moment I'll just say this, there's nothing "difficult" about them, I just hope the explanation will make any sence. The trucks are mounted on a 6x24 train base in the holes closed to the center, the wires of each engine goes thru the opposide hole in the frame. As for the frame, yes that was my biggest concern, specially with the opening in the train in the centre. Most of the stress is taken by the tank and the middle roof part, specially the tank may be a bit over-enginered. It was however not very easy attaching the tank to the train, and should one or the other (tank/middle roof) be removed she'd still bend under her weight. They both do their job together and so far they're doing it right Edited January 9, 2015 by Barduck Share this post Link to post Share on other sites

Kodan Black Posted January 19, 2015 Whoa is that thing massive. The pics with the minifig really put it into perspective. Reminds me of Crocodile Dundee ... "That's not a locomotive, THIS is a locomotive!" Share this post Link to post Share on other sites
zephyr1934 Posted January 20, 2015 Oh man, seeing the underside of the trucks that is great. I remain amazed that you pulled it off. Share this post Link to post Share on other sites

Barduck Posted January 20, 2015 Oh man, seeing the underside of the trucks that is great. I remain amazed that you pulled it off. When I started designing her I've based a lot of the build on DmChylde's 6-wide version. I saw his early designing steps for the trucks: DDA40X by DmChylde, on Flickr and that got me thinking. It would be much easier to build her with train bases as trucks, there are allready the connection points for the motors in place so that would save me a lot of plates etc to make the trucks frames. Only question was, seeing that DmChylde was using the standard LEGO motors sides, would she be able to run with a detailed side? So I took an RC base plate, put 2 motors on it and build a quick and dirty brickwall around it to test it. And it worked. Now I had the space to put the detailed sides on the trucks without having to worry about the motors being in the way. Only thing I did do was to cut the 6 long technic axles by half a stud so that those too wouldn't be touching the sides Share this post Link to post Share on other sites
Redimus Posted January 20, 2015 Do red train bases exist? Share this post Link to post Share on other sites
Barduck Posted January 20, 2015 Obviously, not. My guess is that DmChylde put those in red in LDD for design purposes, to have a better view on what could work and what not (something I do too when designing) Share this post Link to post Share on other sites

zephyr1934 Posted January 24, 2015 That's crazy! I've got train cars shorter than the trucks on that engine. (wow!) Share this post Link to post Share on other sites
