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

[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

[ilovelegosyayXD76]

@starpotter17 nope

[thekoopanator01]

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

[annoyiorangeisawsome]

Dont let it hit your hand period,it will HURT

[SpectralCode]

Cheater! :)

[crazytaxi1000]

cool!!!!

[StickmanStudoes]

Do you ever use curve tracks?

[KINGDOMRIOT]

I love the custom train! Why cant LEGO sell cool models like that?

[batarang69]

@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

[Sagitariuz]

Smart motherfucker ;)

[ballpythondude97]

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.

@ballpythondude97 no and cool

[zaandwy]

This was very useful

[Shinabro21]

This is what I like about Lego. If you don't have it, make it

[ballpythondude97]

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!

[snipatron117]

Thats very clever

[14warr]

Thanks for the help

[lego4555]

super video

[jukieki]

booring



[weslars1]

Where dis you buy that TGV train??

[lego4555]

@weslars1

he made it hisself like eurostar and ice3

[zombiexer1]

Coolio

[qwertypop1337]

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. ; )

[rmike98]

Hey I tried it out and it works great. Nice idea. THANKS

[misterjpj]

Hi I myself have a lot of trains just like you and I have also long trains that I have now tried this trick and he managed really well thanks.

I am from the Netherlands and I am 12 years old.

[dionysos46]

Cette brique deux trous, un plot central, que pourrait t'on faire sans elle, à part des chalets carrés... ;-)

[TheLegoTT]

Can u make isntructions for Eurostar locomotive plz?

[barendduck]

HI this is so cool.

But how many track pieces do you need to build an whole cirkle?

[filuwies]

min 2:33 looks soo cool!!

[MrMariotime123]

amazing vid, and, it works for the non-electric tracks, too!

[chasefilming]

were can i buy this?>

[gekirangerfan]

if only there were 9v flexible tracks

[rytupiop]

wont the train come off the track because of the gaps?

[seinfeldfan7898]

@rytupiop A truck will still fully operate on track segments of 1 stud apart.

[RawesRanches]

good video! Any ways,I needed larger track.

[northlanderdude]

that is just flippin' AWESOME !

[ryancarlopot]

why did it break

[Bubbabink1]

Now lego has special pieces that curve, but this still works!

[erikd217]

oh there is a god, now i know how ur trains dont fall off the track

[MDGGill]

does it work for curves too so you can make tight turns?

[LEGO9vtrainfan]

@MDGGill Yes, although I find the LEGO curves are tight enough as it is! What's interesting is that you can use the half-stud offset on the inside rail of the curve (i.e., put the hinge plate on the outside) with normal curved track pieces to make a curve of larger radius. The result is not nearly as large radius as making curves from straight track, but it can be a good use for your extra curve pieces or to help make a larger layout. Try it!

[legoindyrules]

can you do this with the RC or PF tracks?

[LEGO9vtrainfan]

@legoindyrules Yes! :) You can make long curves from straight pieces LEGO RC/PF train track as well; in fact, it's simpler since there's electrical conductivity/resistance to worry about. Cheers!

[legoindyrules]

@LEGO9vtrainfan alright thanks for answering :)

[TheLegoTT]

@LEGO9vtrainfan Could u make instructions for Eurostar (locomotive) please???

[StephenETavington]

Very nice. Looks like it's time for me to dust off my LEGO train sets!

[trainmad55]

did you make all your hi speed trains? if not tell me where to get them from, thx! =)

[LEGO9vtrainfan]

@trainmad55 Yes, all of my high speed trains are custom models based on the work of James Mathis. I built them using pieces from my collection, and I have some rough instructions I can share too -- send me a personal message. Cheers!

[dbdrdbag]

Brilliant idea! But what about the cracks between the rails? Would they produce a lot of noise?

[LEGO9vtrainfan]

@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. :)

[TheTRAINdood]

That idea is a good one. It saves money on having to buy curved track. If you make it on a bridge youd have to make the bridge curve. but once you do it should just snap into place. Hey, do you have seats in your TGV ? if you do then put people inside and it goes on from there

[zZwuselZz97]

echt super

[Trainmaster189]

Thanks for that tutorial.  Do you have any plans of building a permanent layout for your LEGO high speed trains?

[dansto67]

It is possible to reduce the radius of the curve up to 1.5 meters without loosing the electrical continuity (see the railbricks blog "Only the speed is good enough").

See also my video LEGO_Shinkansen_double_9V_alim­s showing how to get 18 V by putting 2 alims in series. With 2 motors and 18V, my train reached 10 km/h allowwed by the reduced curvature and by the inclination.

[LEGO9vtrainfan]

@dansto67 Thanks for your comment! Yes, I read the blog post on Railbricks and watched your video -- I really like your ideas and want to try them myself. I am concerned about the longevity of the 9V motors running at 18V, but the speed is incredible... ;-)

[dansto67]

@LEGO9vtrainfan

Well, in my video I used 2 motors at 18 V which mean 4 times the usual current. My personnal experience shows that lego motors can support up to 30V during a few seconds without damages. Consequently, you should split the loop into slow sectors at 9V (for cooling down the motor) and fast ones at 18V. This is what I will try next time.

[TheCrunchifiedOne]

You my friend, have too much time and straight 9v tracks. Where did you get all of them?

[Gigdoat]

weird, i was just about to ask you to make a tutorial
