So here is another one of my American route proposals. This one would be easy to make since Baltimore is I think 40 miles from Union Station in Washington, so that would make a good route length that DTG could make. Some good reasons for making this route include: Varied rolling stock, Amtrak and MARC, interesting scenery, especially around the cities, and if it runs to Perryville (but probably won't,) you get a nice view of multiple rivers. Please Dovetail, this would be so fun to do runs on!
I doubt it's gonna happen. I think Marc already refused to give DTG licensing like Septa did. So unless Marc changes their mind or unless DTG does unbranded trains, I don't think you're gonna see it as a DTG release.
