I was just thinking with all the routes available in any simulator game, nobody has ever done a route in Thailand as far as I know and I think that the best route to have would be Siam to Burma railway somewhere set in the 1960's, 1970's or 1980's I think it would be great to have a Thai route in TS2019 Somehow, I'd doubt that DTG would do it since they won't bother with any Australian routes or content! But I'd thought I make the suggestion anyway!
I think it would be a great idea for TS to have some Asian routes. Would add a whole new style of railway and a whole new scenic look to the game. Lines in Vietnam would also be an idea.
There are two Japanese routes and one Chinese route if I remember correctly, but it would be cool to see some more Asian routes added.
