An Airlinesim but for trains

Does anyone know a game like this? Ive played transport fever and open ttd which is the closest ive got but I was wondering if you guys knew any others?

Nothing online I would know of, but try Train Fever. Specifically dedicated to trains. there are multiple addon scenarios/countries.

and it's available on Steam for purchase for $20

Train Fever is outdated. Go for Transport Fever which is not just an update of Train Fever but it also got ships, cars and planes. Of course AS is my favourite game but I enjoy playing some World of Warships, Cities Skylines and Transport Fever from time to time and especially when flying where there is no internet. Overt half of my time in Cities Skylines and Transport Fever was spent when flying so dont think I am a serious gamer. 

Thanks guys
