I used to love Train Dispatcher 2! I'm not sure it runs on modern platforms though. 
I played it a lot in the early 2000s. One of the territories I downloaded was the Allentown-Reading, PA area. I used to railfan there as a young man. I thought the software was very realistic, and it gave me new insight as to some of the train movements I used to see, wrong side main, where trains were held, etc. Auran Trainz, Microsoft Train Simulator and its successors are great, but they focus on running the train. I guess you could create a territory like this in Trainz using the "portal" objects, and just play it from the map view. But that would take a lot of work.
Honestly I wish I had this program again. If nothing else I would like to make a note of the train "line up," their originating and ending points to aid in make-believe on my O gauge layout!
I really enjoyed this sim and wish they would port it to iOS. It would be a much better time-waster than Pinochle 
@rrman please let me know if you get TD2 to work in Windows 10 or iOS 13.3.
