Researching that trackage, does show that if any freight trains were to be in that area, they would be CSX freight trains and not Conrail. (Although you may see a former conrail engine still in blue paint going by on a freight consist, IF any freight does go by there)
CSX apparently has trackage rights along that line, until it gets farther up and then it controls some of it, via the CSX hudson subdivision. (so I read) So maybe some freight does go thru that station. However it's only a 3 track line and all three lines are used for passenger service. One of the lines appaerently is an express line, and the other 2 lines serve trains going north and south, so not much room to have freights going thru, and even if they did stop to wait for an all clear signal, it probably wouldn't be an hour, maybe like 10-15 minutes? And my experience is that passenger trains don't stay longer than 2-3 minutes in a station, they just pick up/drop off passengers and then off they go.
As far as trains go, figure that any line you live near is active, or if not, may someday be, and know that in advance when you buy or rent in an area that's close to a railroad line. Myself, I love trains and so this wouldn't bother me. Although I believe something similiar to this happened with NJT where deisel engines idling all night in winter due to cold weather, prompted complaints from people in area and now some have block heaters so they be shut down at night and still start right up in morning. I know from experience without a block heater in deisels in winter, they won't start if it gets too cold overnight. (Some of the equipment I work with is deisel)
