Is it Sweet Transit? The about section mentions that the developer was part of Factorio.

It even looks like the rail assets were lifted straight from Factorio. I mean if it's all above board it's fine - Factorio's train system is really good.

That said, they're also giving it major updates/overhauls in the upcoming update, so this one would be falling behind if there's no good relationships between the two.

The mechanics or more or less entirely unlike factorio. It’s this really weird city sim / train game hybrid that is pretty crappy at both halves.

Yes, that's the one. Never played it, but from my understanding its effectively just the train system lifted out of Factorio with a game built around it.
