Hey Folks
I am very fond of junctions so I'm starting this thread, let's share our very best junctions here.
I have just created a T-Junction and I'm still testing its performance.
Note: It does not support U-Turns.

It would be a great idea to have a junction competition, what say?

Welcome to the Forum!

I say keep it simple and as compact as possible.

Junction you've posted looks nice, but works less nicely - you got quite a few very short 45° turns there - so the trains are limited at 88 km/h.

For any kind of junction you just have to use longer 45° turns (3 squares) and you're set.

Hey SirkoZ
Thanks for the correction, well I have modified the junction to accomodate higher speeds.
I actually started making this with the Electric Engines but then realized that there will a speed lag in MegLev so I designed two versions of the same junction.
The min. speed for the first one is around 276 kmph, and for the second one is around 330 kmph.
I tested it with MagLev Lev4 with 8 Empty Coal Wagons.


BTW the speed reduction depends on the weight anf turns, because when I tried 45 degree turns only with the engine it didn't show any speed reduction. With 1 Coal wagon it showed slight speed reduction and as I increase the wagons the reduction increases.

The lower one is good although it has one 45° turn 2-square long...

Hmmm..
I think this one is better than the above ones, I tested it with MagLev Lev4 with 6 Coal Wagons, there is no speed reduction!!!

Actually the way it works is that your train should not take a turn while it is already completing a turn, if this happens the train's speed will be reduced. It doesnt matter that you have 3 square 45 degree turn or a 2 square 45 degree turn, it's just that the train should fit in it.

The key here is that the length your train should be at least 1/2 the length of the shortest straight path available, if this is the case, there would be no speed reduction.

The only drawback I see in this junction is that it takes up a lot of space (17x18 tiles).

thats a total waste os space, this line switching junction should have no speed limit and is much smaller:

Hey C-Funky
That's a nice junction, but try running 6-8 length trains (Mono-Rail / MagLev) then you will see the difference. You wont see the speed reduction in Classic / Electric rail because the max speed these rails can gain is not more than 240 I guess, you will see a reduction only when you are at speeds of more then 300-400 kmph.

For the Classic / Electrics the junction I posted in the begining of this thread would do with just a fractional speed reduction and this junction occupies very less space. In fact that is the most compact I junction I've ever made.

owen's half clover leaf is the most compact junction...

well anyway between size and speed loss you're last version of the junction is just too huge for a simple one track t junction...

I really don't understand why you go so far, see my version of you Tjunction, no need to make your path so long and around the whole junction

The problem is that you will need to make the other line longer then to keep speed at both tracks, or you might even need a second tunnel to get on the outside so you have enough space.

The one you are suggesting is indeed a smaller junction but as XeryusTC said to maintain speed, we need to have a longer junction, speed is everything mate...

For the Classic / Electrics the junction I posted in the begining of this thread would do with just a fractional speed reduction and this junction occupies very less space.

The sharpest corners have a max speed of 88km/h. Depending on the set you're using, this might be ok for very early years and some freight trains (if you have wagon speedlimits on), but generally its a design which you'll want to avoid; if only so you dont have to redesign every juction a few years down the track.

But if you're using short freight trains in a spot with limited space, it certainly works
