A TRIUMPH OF RAILWAY ENGINEERING :
Cutting Out the Stifling Glenbrook Tunnel.
Some day there may be a fast service -of trains to the Blue Mountains, jaded city people picture it and hope for it. In the
meantime there is to be an end to the terror of the Glenbrook Tunnel. It is 704 yards long on a grade of 1 in 30, up which
the train laboriously crawls while passengers stifle. A new line , which will miss the tunnelt is nearh) completed. There will
be a tunnel , but it will be only 308 yards long on a grade of 1 in 60 — so better times are in store for mountaineers.
THE work of cutting out the Glenbrook tunnel
and- providing an easier grade up the east
ern slope — the foothills, so to speak— has long
been considered. In the old days of the first
Ziz-zag the feat of negotiating it was considered
quite dangerous, and many a timid paassenger of
those days can recall the nervous prostration that fol
lowed when the -train had been pushed, bumped, and jerked
up over the top of Lapstone, and run to safety to the old
Lucasville platform, part of which is still standing. What
ever were the difficulties and the trials of the old Zig-zag,
it is doubtful whether they were lessened by the journey
through Glenbrook tunnel, which was constructed ' for only
a single- track. To the Railway Commissioners! it has
created, with the expansion of landed interests inland, an
other 'bottle neck' problem, making at times the handling
of trains at this point a most difficult and vexatious mat
ter. The grade, too, has been against efficient handling,
and the work that two engines have to do as they climb
the present 1 in
30 track means
great wear and
tear . and con
sumption of coal.
THE present
deviation will
relieve these diffi-'
culties, and pro
vide a track' with'
a rise' of '1 in 60.
The cost of haul
age will be ma
- terially reduced.

is reached. There
a locomotive de
pot is to be es- .
tablished. This
alone will moan
?a saving of thou
sands, and hav

mountain side
will facilitate the
journey for pas
senger trains.
A Great Engineering Scheme.
Few people realise tlie extent and nature of the under
* taking. As Emu Plains is passed in the train there
can be noticed the new line bearing away in a north
westerly direction,, and Then^ circling back to the exist
ing line near the level crossing the Bathurst-road, It
crosses knapsack Gully, and, skirting up Lapstone Hill, ;
swings round to The' Bluff a rocky, eminence which is well
known to' .visiiors to the little /mountain, village of Glen
orook. The new line then bears away in a north and
north-westerly direction;- and will rejoin the, main line in
the vicinity of Blaxland, but . there ,is much, to,; be; done
before that stage is .reached; .;The topography of the coun-
try is undergoing considerable change, and the throb of In-
dustry is heard on every side. . At first the .surveyors' ,
pegs were,. the only indication of the change. These little
- plnk-and-white posts .*bobbed up' , like so many , mush
rooms,. Lines of .these came through quiet orchards ; ; they ,
caused trouble on a bee; farm;, but still - the pegging went '-
on until it was complete. Then came the engineers and
the navvies. The' new track was opened ,,up; .the trees
that had been unmolested for ages fell to the ground, vic-
tims to the onward -march of- progress. Roads were cut,
a power-house .capable of generating a 2200-volt current
was established - at -Glenbrook, and .water ^supply for the
workers and their families was supplied by the erection of
storage tanks .and pumping facilities to send, the water to .
all parts oif the works. Part of the discarded Zig-zag
was utilised, for running material along;, a tramway , was .
laid down to The Bluff.' camps were formed, and telephone
wires run all over the area of operation.
THE work has been in progress nearly twelve months.
At The Bluff' a 'Titanic task is' being accomplished
in a way that compels admiration. There, in a narrow
mountain gorge, through which runs Glenbrook. Creek, The
Bluff rises almost vertically to a height of about, 750ft, and
through this .wall the new track comes, about 400ft above
the creek. Viewed from the top one wonders how a foot
hold was obtained, .and how the work of hewing. -out the
solid, sandstone was commenced. „ Blasting .operations
Lave been a big factor in shattering the face of the cliff.
The railway engineer of to-day scores with high explosives,
which rip, tear, and -crack the sandstone of the mountain
side in a most astounding way. . While there have been
no big blasts. of the nature. of those fired atdarence, still
there has been some fine shooting. '-A big charge gives
a splendid spectacular display. There is the crash of ! the
explosion, and then comes ? the upheaval of thousands of
tons of earth and stone. Momentarily it poises in the air
like a waterspout, and then it roars downward to the bed

of the creek, echoing and re-echoing around the mountains
like thunder. This goes on: all day, but.it is mostly in
the dinner hour at The Bluff' that shot firing takes jilace.
Time-fuses are sojnetimes used, but blasts of any dimen
sions are electrically fired. '
Piercing the Mountains.
It is at The Bluff that a tunnel has to be pierced, and
already good progress is being made. It will be 300
yards long, and -it has now -been pierced- some distance at
each end; This particular piece of work is all being '
done from a shelf cut into whiat was nothing . but a wall
of rock. To get the material down, a 'funicular railway
had to be ' constructed. Part of this has a drop of.' 1
in 12, while, for, the rest of the journey, downwards, it
is 1 in 3. The miners who do the tunnelling have to
be constantly on the alert for faults in the- rock that
might ca.use a fall of /stone, but little timbering has been --
necessary so far, and the stone has been very dry/ and
free from waterl The tunnel is lit up by electricity,- and
, fans are in operation to keep the air pure. Another
phase of the work at The Bluff is the flying fox. Below , ,
the rocky platform on which the new tracks, will be laid,
a retaining wall has to be constructed, and a flying fox
takes the material down from the top.
:
AT the Blaxland end of the deviation the work, while
not so heavy, is none the less exacting, and some big
'cuttings have to be put through. It has been necessary,
near the Blaxland station, to elevate the Bathurst-road
to enable the new track to be laid. At present a track is
being laid to divert the present line as quickly as possible,
to enable a new cutting to be put through the road now in
use at this point. It was hereabouts that the steam-navvy
was first tried on railway works in this State, and proved
a great success. It works in an almost human-like man
ner. Its great scoop or shovel seizes the earth, and literal
ly shovels it up and tosses it aside with its long derrick
arm. It accounts for about 2| tons each time. There is
still one at work at Emu Plains. Every possible advan
tage has been taken of labour-saving appliances. There
are steam derrick locomotive cranes, which come into the
cutting and pick up huge boulders, and toss them into the .
waggons as if they were so many pebbles. On one of. the ;
cuttings a steam travelling gantry crane traverses the top. ;
Down 50 or 60 ,
feet below are
great cubes of
rock hurled out j
by the last :
blast; the chain,
. with dog hooks, .
. . descends, and
the rocks are
grasped by the ,
hooks; the
word is given .
to haul away,
and off the stone
is ? hurried to the
other end of the
cutting,, dropped
into the waggon,
which gravitates
along the line
until it reaches
its destination. .
Then it tips
up automatically
and hurls its
load into the
gully beneath,
thus bridging it
and making the
bank in a much
surer and quicker
way than the ; „
horse and tip
dray. The huge
arm of a derrick
crane can also be
seen swinging
round heaving the stones out of the way. Headings are
run into the cuttings, and lines laid down for the trucks.
Great beams of wood span the top, on which have been
placed further beams— Chinamen they are called — which
act as a flooring. At intervals there are spaces through
Which are hurled the rock and mullock from the tolp of the .
cutting to the waiting trucks, which are pulled away, by
; horses. Then there are the compressed . air. drills which
* cut their way through the ro.ck. Making, ready for the
blasts, but still more modern, is the 'Jack' hammer, as
?it is called, worke*} by .-the, same medium. It punches
through, the solid -rock like a hammer, and, in places where
the drill could not work. By contrast, there. is the ,navvy
at wopk with the old-hand-rod and water, painfully drilling .
a hole;
Advantages-; of the' Work. : ...
THE cost of- the . deviation is * estimated at about: .
£200,000. It will provide a double track-to and from
the mquntains, while the: Glenbrook Tunnel will ^als be
available for traffic to Sydney — a very important considera- -'
tion in busy times, -and -with an- expanding holiday- traf- '
fic. A: new railway station will , be established ?at Glen-
brook, about half a mile south ;of the present station.
What is to become of the existing station is riot yet known; *
but it is not likely that there will be two stations, as 'some
suppose. The length of the present line between Emu
Plaihs and Blaxland is 'now five miles; ^when. the devia-
tion, is. completed,, it will be eight and a half miles,, thus
adding to the ., mileage, and, incidentally,, the cost, of a
week-end on the mountains. The new line will be re
sponsible for some added charms to the scenic wonders of

the trips up and down the Nepean and' Emu Plains, and the
passengers ?will have opened up to them new vistas as. it
ascends the hills until they reach The Bluff, when the
river will be seen just beneath, but much closer than it is
on the old track. As the train goes around The Bluff there
?will be a view of hill and valley that was never before pos- .
sible. Backward there will be a fine panoramic view of
the plains. As to the men engaged in the work, they

number 1400, mostly navvies. There has been no shortage
of labour offering on this job.
THE men employed/ are generally of a good type, and
. while there are not a'. few 'immigrants, ' Australians
predominate. Tiere is: no evidence of any slackness
about them, although the. job is a day-labour one, .and there
have been no labour difficulties. The fortnightly pay of
the men on the job averages about £6000. Many of them
have their families with them, and live in the rough, primi
tive style of railway .camps. Some of their dwellings are
well and neatly built, and many evidence the touch of a

woman's hand, and the love of home and children. The
main camp near The Bluff has quite a dignified air about
it. It has one road running through it. which has not devi
ated from the. ' surveyor's' line. It has. shops, and stores,
and a post-office, while , boarding-houses and refreshment-'
rooms are much in evidence. ; There is an excellent water
.supply, and the surro.undings, are such that make for very . ,
healthy conditions. The principal officials engaged are: —
Mr. James Fraser, engineer-in-chief; Mr. Kendall, visiting
engineer; and Mr. Butcher, resident engineer. Head
quarters are at Glenbrook, half a mile distant from .
The Bluff.
