First shot at rails- is this intersection done correctly?

[neon jungle]

I think this should allow 1-way trains to enter and exit simultaneously but I've never done this before and its 1am so I might be missing something. Thoughts?

Looks good, up to two trains can use that at the same time. Do think about how they will turn right though... (They will not stop for themselves)

Particularly long trains might have problems turning right,

[willow estuary]

long train turning right can crushes itself

When posting train stuff, it's recommended to hold a signal in handle so it's easy to see train blocks.

But yes it look correct

How long is too long for this

[willow estuary]

long enough that when it turns right it will crashes on its tail

so longer than the circle

[neon jungle]

gotcha

[willow estuary]

You get what I mean

so as long as it’s shorter than the red line its fine

Traffic circles are optimal until...

1. trains are longer than more than half the circle. If that happens the intersection can only handle 1 train at a time.
2. you have a lot of trains trying to get through and start having backed up traffic
3. if you don't have a lot of alternate paths trains can decide to take in case of traffic

Traffic circles are great for small trains and if there's a lot of alternate paths trains can choose from

❤️ That's how I did my first intersections, a long time ago.

At some point my base and trains stopped being cute, and deadlocks & exploding trains started happening.

If you want to keep the general design, reduce this to a T-junction and it'll be fine I think 🤔

   This is simply wrong... Train length does not matter for that, their path is what matters. If two paths cross, they cannot be used at the same time. If they do not, the trains can pass each other no matter their length.

I was trying to start with a 4 way and then delete certain rails to make every other intersection

I’m painfully aware that soon I’ll look back on this with disgust and anguish

Traffic circles can be used by multiple trains, perhaps not in the shape provided above but I've seen 3 trains passing simultaneously, though they were all passing to the right path
