It would be fascinating if we can use ships and ports to transport items someday

I don't think underwater, or underground would work for trains in this game as it currently is... over water bridges, as the original post says, would be a very good idea.

Actually, in OpenTTD, there is a patch that allows building underwater tunnels - in the end, it makes sense. http://roomoramablog.files.wordpress.com/2013/03/underwater-train-in-venice.jpg We might also have a neat transparent tube effect for it, so you could visually see the trains passing underwat...

On the other hand, bridges obscure view. If only allowed to be built over water this is irrelevant. If not, it becomes a problem. A use for underground tunnels may be a path into a fortified area that does not require a break in walls. ...

I agree, tunnels don't serve the same purpose as in OTTD, unless you planning a huge railnetwork which you won't need in 95% of the playthroughs. Bridges on the other hand, would fit very good. I always remember those pesky little "swamps" that i have to build around becuase of a few 2-6 t...

Well, looking back at transport tycoon, adding a bridge would add something to the game since factorio also has water. The addition of an underground rail on the other hand doesn't make sense. In transport tycoon you had mountains for which the tunnels ...

Yes and no. Yes, because train is big and sometimes things are in the way which can't be simply mined. Yes, because as OpenTTD shows, there are tricks in train routing, which enable more traffic, but need underground. No, because different to pipes and underground belt I cannot imagine how that coul...

In addition to a train bridge what about trains being to go underground for a limited distance the same way pipes do.

I like this one. Trains could use more flexibility and this sounds fitting.

Building train bridge by manufacturing and putting different (stone/iron/steel) parts together to span any size body of water

... need not to be very high. Walking, driving with the car and eventually the train, but no buildings. Belts other pipes only orthogonal. This "bridge" has also some more usages: - ok, place pipes on it - you can walk on it, it can be used as bridge over lakes - place also belts? Rails? ...

... against being forced to keep space under and besides the pipes, that you can avoid the perspective problem. But I think to something like this bridge of pipes: http://commons.wikimedia.org/wiki/File:Chemical_Plant_Western_Reclamation.jpg Or pictures you get when you search for chemical plant. ...

It would make really sense, if such a "bridge" can be used to prevent the neighbor pipes from connecting...

... else in between. In my case a transformer, which is not more than a special pole. It is logical, that connecting two networks over more than one bridge doesn't make sense. Using some limiter like one per network seems very arbitrary. Using more than two (or just two that are very far apart) leads ...

... but on the other side: Shortly ago I played Lego with my little nieces; we built a train. And then the blocks ran out and we couldn't finish the bridge. But after some trying we used the Barbie Dreamhouse to build the pillar for one side, and for the other side we used just the bundled stack ...

I think you don't understand fully. :) The rendering of the bridge is just a problem which will always appear. The problem is how to interact with the rest of the world (=main-map). Hm, how can I explain that? I want you for look at the factory-idea ( ...

... In my mind was something like "more expensive than walls and not so expensive like in OTTD". :) But you gave me a good point: Different bridges for different purposes. It's clear that a ladder over the factory is easier/different than a bridge for a car or locomotive. And to bring it ...

this is not really a suggestion, it's more a concept-study. :) I think bridges could be the first step to implement a third dimension into factorio. - Bridges are streets (see https://forums.factorio.com/forum/viewtopic.php?f=6&t=1094 ) "above" ...
