With the release of trainsimcz mod for Koln-Aachen which fills in the gaps of the service mode trains originally for MSB with RSN instead, I have learned of pathing issues exposed with the AI dispatcher going into Koln hbf. It seems regional services use the same tracks in Koln. The services tend to stay put for a good 20-30 mins before they move along which ends up creating traffic on the line. I hope DTG takes a look at this unless they have seen this already and updated it. DTG Jamie Thought I pass this along.
