Factorio Forums

When the rail newtwork raises, the roundabout is our unsung hero. But sometimes, it is not enough. What about something to avoid rail crossings, like a tunnel/bridge? I think a tunnel could be more simple to manipulate graphically. It can have its research, with basic/med/advanced tunnels with increasing costs and length. I'm surprised someone hasn't yet developed this.

This is the mod section, and what you are suggesting requires rework of the game engine. (And was discussed somewhere).
Currently there's no reasonable way of implementing that in lua, that doesn't involve reinvention of a notable bit of the core logic.

I see. Well, people made huge and interesting work with mod like Surfaces and similar others, maybe someone will take this challenge despite the difficulty

hi folks !

i'm sure i am not the only one who would like to put his/her hands on a mod which would allow us to let our trains go underground to....let's see...hmm.. go under our city ? would be awesome. could be a subway or tunnels. i saw another post about that, but the guy was rather asking for a mod requiring the use of a warpgate or something similar. not a tunnel. anyway. i'm sure it must not be an easy thing to design but i wanted to ask... just in case

honestly, i know nothing about modding. but if i had to guess something about this request, i suppose it would involve a teleportation mod for the trains to simulate an underground passage. (with a delay before exiting to make it more realistic). and i think lucianus is right about something: we saw amazing work from the mod developers, so who knows... and perhaps a combination of the teleportation mod + factorissimo would be amazing.

The game has underground belts.

Is it possible for a modder to just clone that and make it for trains?

No.

someone made this; viewtopic.php?f=87&t=12836

it's not underground, but it does make it possible to have trains drive through your buildings

Edit: i don't know if the mod is still active and supported, maybe someone can work with this if its not a active mod anymore?

Hi, I was thinking about this with the Subterra mod. I have hope for the 0.17

Rail Bridges is released!
