How to make long curves from straight pieces of LEGO 9V train track

As requested: How to make the long curve layouts seen in many of my videos from straight pieces of LEGO 9V train track. For more information, see Holger Matthes' original article in Railbricks Issue #1 at www.railbricks.com. Thanks and enjoy!

how many power controllers do u need for a full circle will 2 be enough to make it go fast

[LEGO9vtrainfan]

@ballpythondude97 Good question -- it depends how many 9V train motors your model is using. For one motor, one 9V speed controller is sufficient, but the key is to use multiple power leads to the track every ~3 m (~1/3 of the circle or so) to keep the voltage up over the entire circle. For larger layouts and/or more train motors, using two speed controllers on opposite sides of the circle with correct polarity can work well. Hope this helps.

how many of these does it take to make a circle, and how did u add the extra power to make it go faster?

[LEGO9vtrainfan]

@ballpythondude97 It takes approximately 90 sections of straight track to make a circle with radius ~1.7 m. Cheers!

one question.....at the ned of this video....how did the train crash?

[LEGO9vtrainfan]

@qwertypop1337 Aha, well the train hit my hand as I was holding the camera too close to the tracks. Oops. ; )

@dbdrdbag Thanks for your comments. The gap on the outside rail does lead to some additional noise, but it is a quite satisfying "clickety-clack" that turns into a roar the faster the trains go... I think it's a benefit. :)

@ballpythondude97 no and cool

[ilovelegosyayXD76]

@starpotter17 nope

[bricksntrains55]

it works even better with the new track cause the newer track does not have metal on the rails. just full plastic.

[starpotter17]

do you have to have electric tracks

[thekoopanator01]

where did u get the TGV train?I really wanna know>

[annoyiorangeisawsome]

Dont let it hit your hand period,it will HURT

@KINGDOMRIOT Because they're stingy mofos.

Lego technic sets have been around for ages and still not one siet of something special like a whole car engine. In fact the engines in most of the car models are pretty piss poor as models
