Railfan9 Posted December 7, 2015 Posted December 7, 2015 Ah yes a front runner. I love those cars. Quote
xboxtravis7992 Posted December 7, 2015 Posted December 7, 2015 Looks pretty recognizable! Only thing I can think of to improve is lengthening the model by 4 or 6 studs to include 4-wheel bogies and replacing the red slope pieces with a more muted color. Other than those nitpicks the model is spot on. Quote

Other than those nitpicks the model is spot on. The original only has a 2 wheel setup. If i were to extend the 2 wheel setup any farther I would have to make the trucks swivel which presents another issue. Right now the wheels are at the farthest distance apart while still being able to navigate through connected switch tracks without binding up. . Quote
dr_spock Posted December 7, 2015 Posted December 7, 2015 Good job. It looks the Front Runner part. You are pretty much at the limit for curves. Making it longer, you could encounter derailings like the real Front Runners. Quote

I feel very oblivious, I never noticed that these cars only had two wheel bogies! Good attention to detail. Quote
raven1280 Posted December 7, 2015 Author Posted December 7, 2015 When I get some more black plates I may try to make it sit lower on the wheels. Quote
CrispyBassist Posted December 7, 2015 Posted December 7, 2015 When I get some more black plates I may try to make it sit lower on the wheels. You could try removing the wheels and axles from the big holder piece (2878) too. Sticking the axles through headlight bricks or clip light plates (4081) will keep the axle from sliding back and forth. A side effect will be that the axle can twist in the holders, which may even allow you to lengthen it a bit. Quote
Hod Carrier Posted December 9, 2015 Posted December 9, 2015 I did wonder about the running because it does look a tad top-heavy. However, it's an excellent model and very recognisable. About lengthening the wheelbase. This could be achieved but you would need to force a steering effect onto each axle to prevent binding. You can do this in the same way as model railroad companies do with their long wheelbase cars by adding a pivot slightly inboard of each axle rather than rigidly mounting the axle directly to the car. This gives you something that looks like half a bogie to which to then attach the coupler via a long pivoted bar. As the preceding car enters a bend this forces a steering affect onto the axle through the coupler. Obviously you'd want to limit the amount of steering angle somehow otherwise stability can be compromised, but provided the train keeps moving forward and the couplers remain in tension the car should faithfully follow the car in front. More here. Quote
Electricsteam Posted December 10, 2015 Posted December 10, 2015 I'm not sure where I saw this.... But someone got around the swivel problem by attaching an axel along the length... I think where it met in the middle he put a sping so when it swiveled enough to get around curves it would go back to the middle. Quote
LEGO Train 12 Volts Posted December 10, 2015 Posted December 10, 2015 A little sit lower would be great ...nice Moc anyway! Quote

I think that's Mark Bellis. http://www.brickshelf.com/gallery/mbellis/Trains/Wagons/tube_wagons_underside_loft_feb05.jpg Quote
Electricsteam Posted December 10, 2015 Posted December 10, 2015 I think that's Mark Bellis. http://www.brickshel..._loft_feb05.jpg The vanilla way to solve that problem. The one I saw literally had just a spring covering the two axles to connect it in the middle. It was for a longer version of the radioactive material wagon in that cargo train set Quote
Hod Carrier Posted December 10, 2015 Posted December 10, 2015 Springs for self-centring are not necessary unless you plan to have a large degree of articulation and you're intending to propel (push) the wagon down a siding road ahead of the loco. The neighbouring car will centre the axle through the coupler on a straight in the same way that it will force a steering effect in bends. The trailing axle will take care of itself even if there is no other car coupled to that end thanks to the castoring effect you will naturally get due to the configuration of pivots, just as the wheels on a supermarket shopping cart do.

Lego Dino 500 Posted December 11, 2015 Posted December 11, 2015 Think like a Radio Flyer wagon. Have the 2 wheel bogies connect to the next set like Intermodal cars or connected bogies the right distance apart with the couplers with a pivot on top, and it'll act like normal 4 wheel sets except they're holding up two cars each.

King Aragorn Posted December 11, 2015 Posted December 11, 2015 Amazing wagon ...I had never seen before! Quote
