Would be interesting to know which route that is. Dutch TSC scene is (relatively) active and there are quite a few unofficial but high quality routes available right now.
How do you mean by unofficial - not having NS permission? Most of the stock on the routes is by Chris Trains who does have a NS Licence.
What I meant with unofficial is that the routes are build by regular players, people who are not affiliated with DTG in anyway. And of course you are meant to use Chris Trains rolling stock with those routes. There are quite some "unofficial" routes available. So if DTG was to release a Dutch route it would most likely overlap with an already "unofficial" route. Then I wonder how the quality of that route from DTG would compare to the "unofficial" route. As for rolling stock, would DTG license Chris Trains material or would they built their own trains from the ground up? ps. I'm from the Netherlands so Dutch routes and rolling stock are my main intrest in TSC and the main reason why i feel that TSW is not an option for me due the sheer lack of Dutch content.
The Flirt 3 that in included with Frankfurt - Koblenz was made by Chris Longhurst (ChrisTrains) There was a Payware route which was fictitious that AFAIK used Chris Trains stock. I forget the name but it used to be on the Trainworx page?
