"Is there a new TRS19 route on the DLS in our future?"
Probably not. For this one I've gone over to the Dark Side and put it into the N3V DLC stream, so you may have to fork out a few dollars to run trainz on it.
At the moment it's kind of pending approval (I think). N3V suggested changing the brick wall and the fascia and provided PBR splines for both. You may have noticed the new ones in the video.
In the video, because of the length of the train, I also removed the "impenetrable barrier" that separates the two small ports on the lower level.
