west of the bridge over the New York Division to a point 300 ft. west of
the western portals of the Bergen Hill Tunnels.

_Harrison Transfer Station and Yard._--The necessities for the Harrison
improvements are two-fold: First, as a place to change motive power from
steam to electric, and _vice versa_; second, as a transfer for
passengers from trains destined to the new Station at Seventh Avenue and
33d Street, New York City, to steam or rapid transit trains destined to
the present Jersey City Station, or to the lower part of New York City
_via_ the Hudson and Manhattan Tunnels, and _vice versa_.

All steam trains from Philadelphia, the South, and the West, from New
Jersey seashore resorts, and local trains on the New York Division bound
for the new Pennsylvania Station, will change their motive power from
steam to electric engines at the Harrison Transfer Station. Likewise,
all trains from the Tunnel Line will change from electric to steam
motive power there, and passengers coming from Jersey City and the
southern section of New York City can take through trains at the
Harrison Transfer platforms. It is estimated that the time required to
make this change of motive power, or to transfer passengers, will not
exceed 3-1/2 min.

The plan at Harrison provides at present for two platforms, each 1,100
ft. long and 28 ft. wide, and having ample shelters and waiting rooms,
connected by a 12-ft. tunnel under the tracks, provision being made for
two additional platforms when necessity requires their construction. The
platforms are supported on walls of reinforced concrete, with an
overhang to provide a refuge for employees from passing trains. The
concrete walls are supported on wooden piles, prevented from spreading
by 7/8-in. tie-rods at 10-ft. intervals, and embedded in concrete under
the paving of the platform. As the elevation of the top of the platform
is +21.83, and the top of the piles is +14.54 above mean tide, the piles
will, of course, decay; but, as the embankment has been completed for
some time and is well packed and settled, the concrete being deposited
directly on the embankment, very little trouble from settlement is
anticipated when the piles decay. The surface of the platforms, with the
exception of the edges, is to be of brick, on a concrete base; and, if
settlement occurs, the bricks can be taken up and re-surfaced. The tops
of the platforms are 3 ft. 10
