TRACK ELEVATION.
Scenes Along the P. R. R.
Vast Engineering Diff
culties Overcome.

The work Of elevating the Pennsyl-
vania Railroad Company's tracks is pro-
crossing rapidly considering the giganti c
ready huge, but systematic piles of stone
ara looming up as retaining walls in a
number of places between the depot and
the brow Of the Hill. The construction
Of foundation for these is an immense
task in itself Trenches deep and wide
were dug. Into these long piles were
driven whose Gaping LIS eleven feet be-
low the ground surface Upon this cap
ping rests the retaining walls. Work OF
this character Is being done at intervals
all along for several blocks from the de-
pot. One pile. already completed, extends
ing in which are located the company's
Offices almost to Green street, another
from half way between Warren and Hem
derson streets to Henderson street. where
the wall itself forms one of the abutments
for the Henderson street bridge.
Three of such walls will be built to
support the immense flooring for the
many tracks that must necessarily run
plumb into the depot.
TEMPORARY TRESTLE.
Within the past few days the skeleton
work of an enormous piece of temporar Y
trestle work has been erected from Green
to Warren streets. The natural presump-
ton is that trains will run in upon a
series of such trestIes while the iron and
masonry work which will supplant them
is being erected.
In this vicinity great piles of lumber
and heavy beams, already chiselled and
ready to ut in exact places, are piled in
promiscuous heaps and upon platform
that is giving away beneath their tre-
mendous weight. Within the next week
or ten days, it is presumed, several of
these trestles will stretch from the depot
hillward.
Trenches for the foundation of the
stone abutments for the various street
bridges are being also rapidly dug, spilled
and filed with solid masonry.
On the vacant lot at the corner of
Warren street and Railroad avenue,
mountains of stone are being prepared
for the hands of the small army of
masons employed. The facility for the
handling of these is assisted by a number
Of tall and staunch looking derricks, and
flats on wheels, containing materials and
engines for pumping water from the
trenches and hoisting the immense blocks
OF stone roll up and down the improvised
tracks.
MINUTE CARE REQUISITE.
In the vicinity the north appears to be
progressing but slowly, but it Is here that
the attention of the engineers is concen-
trated. The immense weight of the hun
dreds of trains which will run in and out
of the depot will require the minutest at
tentton to details in the erection of the
structure that Is to support it. Enormous
pumps are constantly required to clear
the trenches of water in order to lay the
foundations therefor. The trenches. how
ever. are being gradually filled with rock
made solid by careful laying and even
cementing. The work is steadily pro-
crossing; and trains that are compare
lively soon to run on an elevated struc-
ture are moving out on schedule time,
and will continue to do 20 till they find
themselves up il the air
Beyond Brunswick STREET the company
has also erected single stretch of iron
trestle work resting upon solid base OF
masonary. Upon this a double track is
laid. The scheme is to continue this
stretch as far as the depot until it is COM
pleted, and then tackle the erection of the
other side. the entire structure to contain
four tracks.
