M-8s do not normally run on the Harlem and Hudson, but they have been spotted there on a few occasions.

The only exceptions I can think of are the P&W "stone train" and the CSX local that switches the small handful of customers (Tulnoy Lumber in The Bronx, Endico Foods in Mt. Vernon, Marval Industries in Mamaroneck) that remain on the Harlem Division and the New Haven main in Westchester. There certainly isn't enough to provide any meaningful interference with passenger traffic on the Hell Gate Route.100% of freight from the national rail network comes in via the Oak Point Connector. The P&W stone trains roll by from Connecticut, but they don't serve Oak Point yard. The Port Morris Branch is long gone, and CSX in theory could run traffic from Cedar Hill to Oak Point, but they don't. CSX local service ends from Cedar Hill in Bridgeport, and from Oak Point in Darien, there is a gap with no local freight service between the two, for which CSX owns trackage rights, but does not have any customers to serve. There's quite a bit of traffic through Oak Point itself between NY&A interchange traffic, and serving industries and I think transload in Oak Point itself, plus the customers around the corner.
