I have quested for this DRA grail myself. I seem to remember Matt saying on a stream that it was only one freight service that went into Dresden GBF to bypass Neustadt, but I have never found it. When people post videos of DRA EB freight runs on YouTube, I have also searched for it. The turnout is at kilometer post 113, allowing you to fast forward to the key moment to see if the service goes into the yard. There is a scenario that heads into that yard that I know of: The Pieschen Predicatment.
I suspect that there isnt one, I believe that the broken service which has a marker behind you (the service which is timed at 50 odd minute service Dresden bound one) *should* have been routed through the yard but it was broken and DTG havent bothered fixing it in the past 10 months.
I have never seen a service pass through Dresden N. gbf station. Then I don't understand why this part was created.
