For several weeks now either one main track or the other has been out of service for work between Harmon and Peekskill. That is a particularly terrible spot to have to go down to single track since the scheduling just happens to have a fair number of meets in this area. Anyway they just installed platform extenders at Cortlandt station, which I do not believe has had these previously, to allow the use of the third track (What is it? track 4?) for passenger trains. Just thought I would point this out. Thank God the third track is still there!
I believe there are still three main tracks in the section between Peekskill and Harmon. This situation might take away some flexibility but it should not tie the railroad up. The trackwork is most likely necessary and important.
