OpenTTD Tutorial: Signalling introduction

In this video I'll explain how to use the path signals in OpenTTD with two examples.

To summarise:
-Path signals work by checking if a train can reach it's destination (the next signal along). If the path to that signal is obstructed, the train will wait.
-One way signals only allow a train to move in one direction. These are pretty important if you want trains to stick to one side of a railway.
-Trains slow down if a 90° turn is shorter than the length of the train, so it's a good idea to have the turns in a junction be as long or longer in order to maximise flow. (This does not count for 45° turns, or two consecutive 45° turns that even out).

What I didn't mention:
-Unless you know what you are doing, you shouldn't put signals inside a junction, only on the outside. If a train stops half way through a junction, it can cause a complete jam.

I'll update the description with the answers to any questions I get regarding t his video, please comment if you need help (if you have my discord, just DM me).

Cheers!

Quick and to the point, not annoying and very helpful. YouTube needs more people like you, thank you.

No matter what I just cannot get my head around this

I didn't think a less than 2 minute tutorial would tell me everything I need to know about path signals, up until now I've only been using block signals because I didn't know how to use path ones. Thank you!

[NatWatGamer]

Another thing to note, Factorio train signals are almost one to one! Awesome video!

[simplymatt]

this is the best tutorial I've seen in a long time, both in terms of length and information. thank you very much

[bananashorts]

Most concise openTTD tutorial about train signals to this date!

[happyguy]

I can't believe you changed my understanding of signals and intersections from spaghetti with meatballs to the logical solution for multiple trains to switching track/directions together with a 2-minuite video

OMG LOVE YOU MY MAN so simple yet effective and i can not express how much i am glad to see this tutorial

[stormcoffeecat]

short, simple, and to the point. perfect tutorial!

[Optimal_Daklen]

bro thought he can drop the best tutorial on signalling in OpenTTD and we wouldn't notice... Thank you buddy. Definitely a sub!

[burstwildfire]

Very quick and helpful tutorial, just takes a bit of messing around with to fully understand this super satisfying mechanic!

[marclegters]

what a good video!! after a little trial and error i understand, is quite simple

In the old version of OpenTTD, I'd always been used to the old block signals, so when the new version only allowed path signals I had a slight learning curve. I figured it out though; always learned faster by doing. They're pretty a effective concept, allowing traffic to flow if not obstructed. In the past, there were no end of delays from trains breaking down halfway across a signal section! 😅

i like how despite your clear instructions i still am stupid enough to not be able to follow them, so i ended up spending like 200 grand on a mountain, bridge and tunnel system to avoid the intersection alltogether 🤣🤣🤣🤣

[bepponen]

very nice, thank u. ive been trying to ctrl drag the main signals :D now i know what i did wrong

[EloLeChan]

signalling in OpenTTD is absolutely essential

[mixtape]

I just started playing open TTD AND THIS IS SO FUCKING SIMPLE THANK YOU

[kmk]

Straight up jingling it, and by it lets just say, my bells

[FloraJoannaK]

Useful! I've dabbled with OpenTTD and it's a fun game, but I make some glorious spaghetti from those train tracks! 🤭🤭

So, to double check for clarification…
One way signals are like one way gates in that trains won’t go down a track if it means going the wrong way through a path signal?
and
Regular path signals are like signals in, say, the Minecraft create mod, in that they section off parts of the track, and if there’s a train on the track section ahead of a signal, then the signal turns red and trains will stop at it?
