I Don't know if i'm the only one who wants to be a Greek Suburban Train Line in Train Simulator, It can Start from The Athens Airoport and ends in Kiato. There are no trains in train simulator that has the real trains in this route. the train that it's in this line is the Siemens Desiro EMU.
I like the idea but there’s likely no demand for a Greek route, they’re not known for their railway systems like Germany or the UK
