yoshi98bc Posted September 16, 2017 I'm having some issues getting the correct speed with L Motors. I've geared it 12:20 and still seems a bit slow for a diesel loco. I'm buidling a SD70 with 3 wheel trucks. Should it be geared differently. Was wondering if I am doing something incorrectly. Any advise would be helpful.

LEGO Train 12 Volts Posted September 16, 2017 (edited) Gear 12 teeth on the wheels and 20 teeth on the motor? Edited September 16, 2017 by LEGO Train 12 Volts Share this post Link to post Share on other sites
LEGO Train 12 Volts Posted September 17, 2017 I've a diesel shunter with a gear ratio of 12:12 and it works smoothly and rather quickly, so I can immagine that your locomotive is faster then my ...but also less powerful. Maybe your locomotive is too heavy? Share this post Link to post Share on other sites
cgarison Posted September 18, 2017 On my heavy, 8 wide/50+ stud long locomotive, I am using two L-motors with 1-1 gear to the drive wheels. It is not a fast locomotive, but it is acceptable. This setup also provides more than enough power to pull more than 30 train cars that are as heavy as the BMR box car or heavier(http://brickmodelrailroader.com/index.php/2017/05/17/bmr-box-car-instruction-kit-update-and-other-future-kits/).

ALCO Posted September 18, 2017 BMR box cars roll easy with ball bearings! I have to but blocks on my track to keep mine from rolling off the table! Share this post Link to post Share on other sites

dr_spock Posted September 19, 2017 My PRR FF1 locomotive has a single L motor. I think it is geared 12:20. It is slow but the prototype engine only has a maximum speed of around 20 M.P.H. Pulling power is pretty good. Share this post Link to post Share on other sites

All my rolling stock have ball bearings Battery Box: I am using the AAA battery box with Eneloop rechargeable batteries for a total of 7.2V. As far as the bearings, that makes the rolling stock easy to pull, but the weight of the car is still a factor and all the rolling stock on a PennLUG display will be heavy because of the detail they add.

The link you posted goes to Flickr. If you want to post the pictures here, you can follow the tutorial below. It's not quite up-to-date, but the principle is exactly the same. We can then see what you have done to the Emerald Night, without having to click the links. The picture you wanted to post was this one, I believe: IMG_20170921_191758965_HDR by Cesar Cuevas, on Flickr People here are unwilling to click on unknown links as we have had problems with spammers, and so the link you posted could easily go to some malware or something!

cacg88 Posted September 23, 2017 @ColletArrow thanks for the message, I did it with my cell phone and I didn't realize it was uploaded with the link option until you post the reply, my bad. Share this post Link to post Share on other sites
