This service is still not fixed with the update. Inbound trains are backing up just South of Crestwood preventing the player service from crossing over to the station. The initial AI train in this backup is just past a switch that puts it onto the player route, so its not a red light issue, but more likely a path issue. This tread in the PC discussion Harlem Line Ai Issues And Red Signal Bug | Dovetail Games Forums has pictures of this issue.
