hello all, i know it seems like a stupid question, but im wondering if any open source simulators related to signaling exist?

It's not open source, but Simsig is free to download and use. Some scenarios have to be paid for, but there are a variety of free ones to try.

I don't think there are any free ones now.

I first came across Simsig several years ago and was fascinated by it. I watched several YT videos, but never actually tried it, for real. At the time, I think there were many free 'stations' to try.

It did look kind of complicated.

A free signalling type simulator is Train Director - see https://www.backerstreet.com/traindir/en/trdireng.php , whence this decription
Train Director is a clone of the popular Train Dispatcher simulation software. With Train Director you can simulate the work of the Centralized Traffic Control (CTC). Your task is to direct trains running in a territory to their final destination, by throwing switches and clearing signals. Penalties are collected for incorrect or inefficient operations, or for trains arriving late. You can also create your own territories with the included track layout editor. Train Director is available for Windows (95, XP, 7, 8, 10) but can be executed on Mac OS X and Linux using Wine (see below).
(I don't know the current status of Train Dispatcher)

While there are a couple of British 'territories', it is pretty international - do not expect an accurate simulation of Brtish signalling practice, but if you just want a game to work trains through a station/larger area by setting routes/clearing signals it is quite fun. And as stated, it it is possible to create your own territories and timetables (not that I've done so) ...

Just noticed this post. There is pcrail, it is free to use (you've got to appearently pay for something but I have been playing without any disruptions?). PCrail mostly includes simulations of Absolute Block signalling, but there are also simulations of modern signalling centres and there are some simulations from other countries as well. Another absolutely awesome software is Block Post, it is unfortunately paid but from the videos I've seen I can say that it is a very accurate simulator of Absolute Block signalling.
