AUSTRALIA'S FIRST 100 YEARS i'OF RAIL
'I'HE EVOLUTION OF
ELECTRIC RAILWAYS
Australia entered the railway age
around 1850. In the following years,
railways changed the face of our
country, sometimes at a startling rate.
By BRYAN MAHER
In Sydney, a start was made at
Redfern and a ceremonial sod was
turned in 1850, but progress was
slow and arguments raged over
what gauge to choose. The companies knew full well that the
English Parliament Bill of 1840 required all railways to be built to the
standard 4ft 8-1/2in, but were also
80
SILICON CHIP
aware that the same Parliament
had ratified Ireland's decision to
adopt the 5ft 3in "Irish" gauge.
Now the Sydney Railway Company had employed an Irishman,
Mr. Shields, as chief designer who
promptly decided that Sydney's
railway should be built to 5ft 3in
gauge.
Simultaneously, another group,
the Hunter River Railway Company,
was formed to construct a standard
gauge system from Newcastle to
Maitland and north, while three different companies were making
plans to link Melbourne with Port
Melbourne and Geelong.
Of the three Melbourne starters,
only one, the Melbourne And Hobson's Bay Railway Company, actually built a railway. They also had
an Irish engineer who, reinforced
by the Sydney Railway Company's
choice of a 5ft 3in gauge, chose that
gauge for Victoria. Their first train
ran from Flinders Street to Sandridge in September 1854, winning
the honour as the first train in
Australia.

locomotive weighed 228 tonnes,
developed 2475 horsepower
(1.85MW), and produced 51,000lhs
drawhar pull. (Photo courtesy

By 1857 a service was opened
from Geelong to Melbourne, partly
by train and partly by ferry. Sad to
say, by 1861 the Railway Company
was no longer financially viable
and a State Government takeover
was necessary.
Meanwhile, back in Sydney town,
engineer Mr. Shields had been succeeded by Mr. Wallace, an
Englishman and proud of it, a
staunch believer in Rule Britannia
and English laws and customs. Yes
you guessed it, bemused reader,
their new engineer would have no
part of this 5ft 3in nonsense and
pointing out the error of their ways
told his masters, the Sydney
Railway Company, that he would
build to the English standard 4ft
8-1/2in gauge. And he did.
The next year, 1855, some 379
days behind the Victorians, the first
train in NSW ran from Redfern to
Granville (then called Parramatta).
Within five years the line had been
extended to Blacktown, with
Penrith reached by 1863.
In Newcastle, the Hunter River
Railway Company opened its line in
1857. This was after four years of
planning, surveys, financial
troubles and building, but the company had been forced to accept
Government intervention.
Both the Sydney and the Hunter

River Railway Companies remained
solvent for less than one year from
their start of operations. By the end
of 1855 both had been taken over by
the NSW Government, believed to
be the first time ever a Government
had owned and operated a railway.
South Australia joined the club
only 210 days after Sydney's big
opening ceremony by building a 5ft
3in gauge line from Adelaide to Port
Adelaide. This extended to Gawler
the next year, 1857, and to Victor
Harbour by 1864.
Queensland, for economy, chose
the narrow 3ft 6in gauge for their
first line which was nowhere near
Brisbane, but ran west from
Ipswich to Grandchester in 1865
and to Gatton the next year. Construction of the next westward
stage to Toowoomba involved the
ascent of the Great Dividing Range
but remarkably that task took only
one more year, in 1867.
Turning south, the builders constructed their line along the
western side of and roughly
parallel to the range to reach Warwick in 1871. Only then was
Brisbane City to enter into the
railway age, the extension from
Ipswich to Brisbane being completed in 1875.

THE FIRST FIVE NSW "38" class steam locomotives were streamlined, weighed 201 tonnes, produced 2250 horsepower
and were built by Clyde Engineering. The one-piece cast steel mainframe included the front buffer beam, all cylinders
and the main air reservoir, as well as mountings for the axle-boxes, boiler, air pumps and firebox. (Photo courtesy SRA).
In company with Queensland,
and again for economic reasons,
Western Australia, Tasmania and
Northern Territory all finished up
with narrow gauge 3ft 6in systems,
although for a short while
Tasmania went through a silly
period with two different companies building in different gauges,
5ft 3in and 3ft 6in.
After a Western Australian logging line had run from Brusselton to
Yogamw for seven or eight years, a
passenger and freight railway was
put into operation from Geraldton
to Northampton in 1879. Thus it
was not until 1881 that the citizens
of Perth saw their first line from
Perth to Fremantle. The Geraldton
and Perth systems remained
separate for another 13 years until
finally joined in 1894.

New South Wales
The NSW system quickly extended westwards over the Blue Mountains, reaching Bourke by 1885.
Simultaneously, construction proceeded south from Sydney to reach
Albury by 1881 with connection to
Melbourne two years later.
All this time, Newcastle had been
the centre of the thriving Northern
Railway System. By 1857, the track
extended as far north as Maitland,
then followed more tracklaying
through the lush green Hunter
River valley via Singleton,
Muswellbrook and Murrurundi. So
far so good. But ahead was the
steep climb up the Great Dividing
Range.
Undaunted, the builders attacked
the mountain and with many a
twisting turn and some large creek
bridges managed to reach the summit in the middle of the Ardglen tunnel. From there, the line proceeded
down a steep slope to the plateau
levels of Willow Tree and Quirindi.
To this day that section remains
exactly the same steep, single
track, but track circuit signalling,
heavy rail and centralised traffic
control keep trains moving quickly.
Loaded trains still require doubleheading over the peak of the grade
with the powerful 81 class dieselelectric locomotives.
Driving on northwards the track
builders reached Tamworth by
1878, famous for having installed
the first electric street lighting in
an Australian country city. But the
proposed line ahead looked
awesome indeed.
To reach prospective customers
the line ascended ever upward to
Armidale, Guyra and Glen Innes.
And it reached higher still through
the tiny town of Ben Lamond, at
4517 feet above sea level, the
highest trainline on this continent,
and higher than most standard
gauge railways of Europe.
Thankfully, from this point, the
terrain falls all the way to the
Queensland border and Newcastleto-Brisbane travel was a safe, comfortable affair by 1888.
Farmers Australia-wide then
twisted the political arms of every
government and in short order
branch lines snaked out all over the
country, giving rail access to 90%
of our sons-of-the-land and their
produce by 1900.
Built partly as "ballot box expediency", many branches were built
too cheaply and quickly, with steep
grades, sharp curves and very light
rail. Our entire country is even yet
suffering the resultant legacy of
slow running speeds and high
operating costs.
Locomotives
NSW locomotives began with little No.1, an 0-4-2 type, to be followed by a few small designs until
mass production of the fast "12"
class began in 1877. The heavier
but slower "S" or "30" class, a
4-6-4 tank type of which hundreds
were built, was the mainstay of
Sydney's suburban steam trains
from 1880 to 1930, and of Newcastle's right up to the late 1950's.
Between 1890 and the turn of the
century, two steam locomotive
classes important to the development of the state were built. These
were the 4-6-0 "P" or 32 and 33
class for passenger service, and the
2-8-0 "T" or 50 and 51 class built in
Sydney by the Clyde Engineering
Company. More than 100 of each
class were built and all did stirling
service for 70 or so years.
The pride of the state for many
years was the "36" class. Especially at night, their "snorting" sound
and the glare of their headlamp
gave such an impression of immense power wanting to be
unleashed that the lure of being
carried to places unknown changed
many FI bystander into an avid
woulrl-be traveller. Every night the

prestige Melbourne Limited Express roared out of Sydney headed
by two of these well-loved machines
and who could but not watch in
awe.
Forty two of this class were built
from 1924 on, but around 1942 even
they were eclipsed by New South
Wales' last steam design, the
"C38" class.
South Australia
South Australia in 1886 made
history by joining the Victorian
system at Serviceton using the
same 5ft 3in gauge. After further
expansion, South Australia declared the broad gauge too expensive for some small lines and built
tracks north of Port Pirie in the
cheaper 3ft 6in gauge.
Years later, in 1917, the Federal
Government, to its everlasting
credit, built the Trans-Australian
Railway from Port Augusta to
Kalgoorlie in the English standard
gauge, extending to Port Pirie in
1937. Thus it is that Port Pirie
(along with the city of Vaxjo in
Sweden) qualifies as a member of a
very exclusive club - those having
railway yards where some tracks
have four rails.
Parts of the Port Pirie yard use
one common rail on the left, a second rail 3ft 6in to the right, a third
rail at 4ft 8-1/2in and a fourth rail
at 5ft 3in. Wow! The sight of a set
of points on such a track is a joy to
behold!
That changed again in December
1986 when Australian National
changed the 5ft 3in Adelaide-Port
Pirie track to standard gauge by
moving one rail inwards 165mm
over the whole 160km length of
single track. It also constructed
12km of new track. Islington terminal now has mixed-gauge tracks,
including dual-gauge points.
South Australia's 5ft 3in Irish
gauge system could boast some excellent examples of large steam
locomotive design in the American
style. This was exemplified in the
520 class streamlined 4-8-4 express
locos and the 500 class 4-8-4 which
were among the most powerful
locomotives ever to run in this
country.
The 500 class was unique in that
they had an extra set of steam
pistons and cylinders driving the
four trailing bogie wheels under the
firebox. This increased the
drawbar pull at low speeds, being
disconnected for high speed
running.

The whole 66kV line from
Hamilton substation in Newcastle
to St. Leonards substation in
Sydney was designed to carry 200
amperes, and at full current 6000
volts was lost over the length of the
line. For the first time in Australia,
two large cities had their power
systems synchronised and joined.

believed to be the second largest in
the world on narrow gauge, but
more of that in a later episode.
A side effect of the choice of narrow gauge is the ability to turn a
train in a tighter curve, allowing
branch and main lines to be laid in
a city street and even turn a 90
degree corner. Rockhampton and
other cities regret this to the present day. Even Brisbane people suffered freight trains in the streets of
"The Gabba" up until 1973.
Early electrification
The absolute first Electric Traction of any type in Australia was an
electric tramway using a direct current overhead trolley wire system
in Sydney, from Waverley to Bondi
Junction. This was in operation
from 9th November, 1890. Direct
current supply was generated by
the New South Wales Railways at
an installation a short distance
away in the direction of Randwick.
That little DC generator near
Randwick marked the first entry into the electricity generating
business by the NSW Railways,
starting an enterprise which continued to grow for the following
seventy years.
The Railways Department during
that time not only generated all
power used by electric trams,
trains, stations , yardlighting,
workshops and signals in the
Newcastle, Sydney and Blue Mountains districts, they also supplied,
84
SILICON CHIP
owned and operated at Newcastle
the largest electric and hydraulic
coal loading wharf system on the
Pacific Ocean.
Furthermore, in that period the
New South Wales Railways
operated 50Hz and 25Hz coal burning power stations at Ultimo and
White Bay in Sydney and at Zara
Street in Newcastle, and for a long
time owned some of the largest synchronous motors in Australia, 10
megawatts in Newcastle and 30
megawatts in Sydney.
During that time the Zara Street
plant supplied 90 percent of all
power used in Newcastle and its
suburbs by domestic and industrial
users. Expanding gradually, the
Railways Department built and
operated a large system of high
voltage feeders from their power
stations to many country towns and
cities.
33kV lines ran from Newcastle to
the Hunter River Valley and up the
north coast towards Grafton. 66kV
lines ran from Sydney to the Blue
Mountains and also Australia's
first intercity power line interconnector, also a 66kV line, was built
in 1942 to join Newcastle and
Sydney.
One 960-metre long span of that
Newcastle-Sydney interconnector
across the Hawkesbury River was
believed to be the longest power
line span on wooden poles in the
world. Originally built using
19-strand 10-gauge cadmium-
Melbourne became the first
Australian city to boast electric
suburban trains when in 1918 some
wooden carriages , previously
steam-hauled, were converted to
electric traction by the fitting of
pantographs, control gear and new
bogies containing electric motors.
Overhead wiring construction
was proceeding on a number of
suburban lines and the first electric
train ran from Sandringham to
Essendon in 1919. Construction of
AC-DC substations and overhead
conductors above the tracks continued and Melbourne's 1500 volt
DC electric suburban railway
system eventually grew very large.
Australia's early use of electric
locomotives was confined to the
coalfields in the eastern corner of
Victoria where the very considerable brown coal deposits are
mined by open cut methods. Victoria's first electrically hauled coal
train ran in 1923.
Melbourne trams
The Melbourne Electric Tramway system has, since quite early
days, been working with the
railways in shifting millions of people. Nowadays this system is the only extensive electric tramway
system remaining in Australia.
A shining example to the rest of
Australia, Melbourne has extended
its tram-tracks and purchased
many new tramcars. The up-to-date
"Z" class, of which 215 new cars
have been put into service over a
ten-year period, are being
augmented by the latest order of 52
modern "A" class trams.

Metropolitan Transport Authority
for the supply of 130 Articulated
Light Rail Vehicles for use on long
tram routes and later on two converted railway routes. These advanced vehicles consist of two cars
sharing three bogies. Propulsion by
two 600 volt DC 195kW AEG traction motors can speed the 32.5

Melbourne showed the world
that the age of construction of 1500
volt DC city underground railways
was still alive and well by opening
their City Loop Line in 1981. Circling around the city from Spencer
Street Station via Flagstaff,
Museum and Parliament Stations to
Flinders Street or outer suburbs,
this new line takes suburban
passengers within walking distance
of their city workplace, easing
street traffic congestion.
Adelaide's longest surviving Electric Tramway, the famous fast
Glenelg Tram, has always been an
example to Australia of the
quickest way to move people.
The people of Brisbane were for
many years served well by an electric tramway installation which
reached the peak of its importance
about 1930. Sadly, Brisbane eventually followed the lead of many
other cities and scrapped all electric trams in favour of diesel buses.
Next month, we continue with a
description of the Newcastle and
Sydney tram systems.
