Screw wikipedia. I’m told it is “improper” to link to “a blog” in articles, but yet you still consider me a valid historical source?

Bit of a late reply, but I looked up your question. The tracks were relocated into the cut in the 1950’s, in order to eliminate two grade crossings in the town. Apparently they were rather hazardous and each required a person to man each, 24/7.

I found it really fascinating that in the Mount Kisco postcard, that white house on the right (with the 3 arches) , I actually lived in that building for a while in the 90’s. According my parents, when we lived there, that’s when I started to take an interest on the Harlem Line. I remember it had a nice kitchen window to view the station and all the trains go by. The M1/M3, Genesis and so on.

I think they lowered the tracks into the cut where they are now. The station building shown is still there now, and it is higher up than the tracks are.
