Dr Snotson Posted March 31, 2021 (edited) DB KLV 53 Hi, this time I want to share a really small vessel with you which gave me countless sleepless nights. P1110480 by Simon Jakobi, auf Flickr To be honest, designing such tiny vehicles is a nightmare compared to the big engines! P1110485 by Simon Jakobi, auf Flickr This is my interpretation of the KLV 53 "Rottenkraftwagen" of the Deutsche Bahn. P1110476 by Simon Jakobi, auf Flickr I learned from the first tests, that when it comes to the constellation of low weight and two axles all wheels have to be powered to avoid hang-ups on switches. DB BR KVL 53 drivetrain Simon Jakobi by Simon Jakobi, auf Flickr That`s why both axles are powered via worm screw by an excentric PF-M-motor beside an "excentric center" axle underneath the loading platform. P1110472 by Simon Jakobi, auf Flickr The motor is controlled via PF-IR-Receiver. The adapters are covered by the chains and the maintainance and construction site stuff. P1110463 by Simon Jakobi, auf Flickr Power supply is an old black 9-V-battery underneath the flat car which is connected to the second output of the IR-receiver... No PF-cables or PF-adapters were harmed. P1110468 by Simon Jakobi, auf Flickr The result is a slow but strong and reliable engine with precise speed controll perfect for low speed action in the "Bahnbetriebswerk" on our LUG-layout. I hope, you like my approach. Bye, Simon! Edited April 3, 2021 by Dr Snotson Share this post Link to post Share on other sites
Vilhelm22 Posted March 31, 2021 Very nice MOC and impressive concealing of the PF parts. Frequently there’s use of a battery box or receiver as a piece of cargo in these type builds, but clearly not here. Great work! Share this post Link to post Share on other sites
Asper Posted April 1, 2021 Wow! This would be a wonderful model without the motor. But the PF drive makes IT perfekt. Share this post Link to post Share on other sites
Feuer Zug Posted April 1, 2021 Your drive train is perfect. Slow, yet flat enough to provide everything necessary for movement. The random assortment of equipment gives it the proper look and the portable toilet is hilarious. Share this post Link to post Share on other sites
zephyr1934 Posted April 1, 2021 Some amazing engineering (and I like the heart on the privy door) Share this post Link to post Share on other sites
Dr Snotson Posted April 2, 2021 Thank you guys! I hope, I find some time to apply the decals to my KöF II and shoot some nice pics over the easter holidays. It shares the Idea of the drivetrain with the same combination of PF-components with my KVL. Greeting, Simon! Share this post Link to post Share on other sites
Pdaitabird Posted April 3, 2021 Great job powering such a small vehicle! The detailing looks good too. Share this post Link to post Share on other sites
LEGO Train 12 Volts Posted April 3, 2021 Lovely MOC ...it could be an original Lego set! Share this post Link to post Share on other sites

As someone explains in the comments here, you lose a bit of the voltage, slowing your train down: It's a very nice model though - lots of nice little details.

But in this case I really like the #100%LEGOsolution plus combining rather old and rather new components. As I mentioned on flickr and EB the other day - crazy times lay ahead of us regarding that mysterious circuit cubes! Share this post Link to post Share on other sites
TuffTuffTuff Posted April 4, 2021 Wonderful! So many lovely details. Just amaziing how you integrated the engine in so limited space. You could also place a small container with a PU hub inside on the flat car. How does that worm screw work? Could you share a picture from below, please?
