Could you make your Video with OBS, Shadow Play or other Dislay recording Software and not filming your Monitor?

So you follow it up with another one word answer :lol:

I have a question about this. Does it save space versus, say, having all 4 tracks in tunnels side by side, and having a one tile piece of open air occasionally for signals?

I would say not but you would see more trains. OTOH those bridges would likely see some performance degradation on sub-maglev trains with all the up and downing

It does. It's not practical, for me, to build 4-tracking like that in entirety, although it's handy when threading through tight areas. The second example was constrained by a future interchange for tunneled expressways (I think -- it's been about a couple of years since either build captured there). Add two more rows for the open-air signaling. The method's a little off-putting for stations or bends but may be handy for subways where bi-directional express running would skip overhead local stations, although I myself do fine with 1 signal per 11 tiles along subway lines (e.g., https://youtu.be/d5OfYfpSJ7k ).

It would work extremely well if you have a patch-pack which allows you to have signals in tunnels. Then you don't even need to bother with the signal gaps and bridges.

^^ I hear you although the game might lose its challenges were it to become less restrictive. In addition, the lower deck needn't be tunneled. By the way, I've found 11-tile spacing for tunneled subways easily doable. A dynamic example wherein I'm sometimes compelled to increase the signal spacing to 13 tiles ends this post.

Heh heh..all these years until just last week I'd very often found myself wondering why so many people filmed their videos or films in drafty areas, because just like my earlier clip here waviness blights output they share. I never filmed my screen. Its wavy appearance comes from the second tool, the timelapsing one; I'm satisfied with my screen capturing app. I'm glad you asked me this, because I browsed around for another one: might the following output of mine be satisfactory, because now the timelapsed motion of panning around the map brings on bluriness?

When coop tried this design 6 years ago, it ended up being excessive for the transport demand using the given network and using the train we chose. It was still fun while it lasted.

That really is space saving but OpenTTD won't let you have signals in tunnels and bridges, which is a pain when I'm making industry lines that span across sea.

Ha, this is why I span water by a sequence of shorter bridges, and 1-tile islands between them.

There is a patch that does allow signals in tunnels and on bridges. Alternatively, you could use something like JGR's Patch Pack, which includes that patch, and many other interesting features.

Or, you could try Alberth's suggestion, however, depending on the size of sea/lake that you're trying to cross, that could get rather expensive with all the land you'd have to raise!

Yeah, but that would use a lot more money because you would have to raise land (On Water!!!) and build a series of bridges that may cost more depending on what you have set AND if you are broke in OpenTTD and can't afford to raise land on water (that's like £7000) then it's not practical. Also, bridges across stations would be nice... because it's very realistic.

If you're broke, you probably don't need to be building double deck 4 track railways...
He's like, some kind of OpenTTD developer.

Well yes but that doesn't mean it wouldn't be nice not having to make artificial private islands solely for the purpose of railway signaling.

You just blew my brain by reminding it was SIX years ago :0
