The Port Morris Branch crosses under Westchester Avenue between Brook Avenue and
St. Ann's Avenue. The White Plains Road line of the IRT (#2 train) emerges from a tunnel
just east of the Port Morris Branch and is elevated over Westchester Avenue when it
crosses the Port Morris Branch.
The area just north of Westchester Avenue between Brook Avenue and St. Ann's Avenue
seems to have been the
Westchester Avenue Yard
at an intermediate point between the Oak Point yard to the south and the connection
to the Harlem Line to the north. The southern part of the yard area was
taken over by South Bronx High School for multi-sport athletic fields
(the Merrill Lynch Field of Dreams),
but a corridor was left for the rail line right-of-way and there was a pedestrian bridge
over the line.
Unfortunately, for the circumferential line, the crossing was about equidistant between
the 3rd Ave./149th Street Station to the west and the Jackson Avenue Station to the
east, making a extremely unlikely that a tunnel or viaduct could have been built for direct
transfer between the circumferential subway and the IRT.
However, there was a post office and vacant lots adjacent to the tracks at this point,
so this still could have been a good spot for a station. Curiously, my 2006 Hagstrom map gives
the path of the Port Morris Branch as Hegney Place and there is a corresponding
street sign on the south side of Westchester Ave. Hegney Place does run intermittently
along the tracks north of here, so perhaps there is/was consideration of filling
in the trench and conversion to a street.
West of the Westchester Avenue yard is a vibrant shopping district on Third Avenue.
Parts of a wall have what appears to be some kind of Art deco ornamentation.
However, a gentleman who used to work for NYC Transit told me that they are
probably clay liners for cable ducts that separated power cables for the third
rail. Some of the ducts appear to be covered over with a concrete shell that
was presumably removed when the cables were removed - either by the railroad
or by metal scavengers from the neighborhood.
In 2012, Via Verde opened and covered a portion of the ROW just south
of East 156th street, and the bridges north of 156th Street were filled in.
This severed the line and reduced the possibility of reuse for transit.
