It's curious that despite trains and rail networks being a perennial nerdy favorite, the simulation game selection feels somewhat limited.

For example is there any that simulate real-world signaling systems, such as ETCS or it's national peers? Or are the different systems truly so generic that you can just substitute them with generic signaling mechanisms?

Recently I've been playing Factorio and the trains are fun challenge there, but the tools to build/design/analyze rail networks feel very limited (at least in vanilla base game). So now I kinda have bit of an itch for better rail game but haven't found one yet. And from the looks of it I don't think Locomotion is it either
