I cant"t get to the track where i have to terminate my service as there is another train blocking the path (and i am presumably blocking him). I was running a bit late.
I have not tried that service, but there are a number of runs on Harlem that have the red light issue, so are unable to complete. This problem is separate from the save game problem which DTG seems to be correcting.
I went in and ran this service, and it is fine. The issue is there is an inbound train occupying the same track you need at North White Plains and you have to wait for it to clear, and it will, before you will get a proceed signal to enter the station, then the yard.
