Fresh Pond yard is clogged today, but more frequent service from Oak Island should help somewhat. The challenge is that TriBoroRX/Interborough would use up the ROW on the Bay Ridge which has effectively been turned into another yard. The stone trains also come from Cedar Hill, so those would have to be put into Fresh Pond and not left out in the makeshift yard on the Bay Ridge.
Oak Point would be far better off, as it would no longer be handling all the Fresh Pond traffic, which is most of what its handling today, and would only be handling local freight for the immediate area and a few remaining customers on the New Haven and Harlem Lines.
Hence why I don't think that a two-tube tunnel makes any sense for freight, I think one is just fine.

Nope. That's NY&A, all freight. No LIRR service on there.

Electrify it. We need to start electrifying major freight lines anyway, and this one would dovetail nicely with the New Haven Line.
