SWINDON
--the town on the hill--dates back atleast eight
centuries and is mentioned in theDomesday Book. It was an
ancient market town of some note when the Great Western
Railway came into being.
Historic Steam :-- The first types of true motor
cars were Steam Engines applied to Vehicles. This fact alone would not have guaranteed them
against competition by other kinds of motors if, as far
as the railways are concerned, locomotives had not
immediately proved to be such powerful and practical
engines able to meet any demand. Even the most sceptical
individuals were soon convinced. In forty years England
had passed from the few kilometres of the Liverpool-
Manchester railway of 1830 to almost 22,000 kilometres in
1870.
The
Frame Section 2
The Frame is the Chasis of all Steam
Locomotives supporting the Drive Wheels the Truck Wheels
and Braking System on the underneath section and the
Cabin, Boiler,Fire Box and Smoke Box on the Upperside .
The Fire Box
Section 3
The Fire Box is attached to the Rear of the Boiler and is
attached to the Upperside of the Frame in front of the
Cabin , with the Grate and Ashe Pan on the underside of
the Frame , There is a shuttered opening in the rear of
the Fire Box for loading Coal, which burns on the Grate,
the ashe falls through onto the Ashe Pan.
The
Swindon Factory
Section 4
The Swindon Works Establishments for
the constructlion and repair of locomotives, carriages,
and wagons throughout the world. The Works were under the
control of the Great Western Railway Company's Chief
Mechanical Engineer, Mr. C. B. Collett, O.B.E., J.P.,
M.Inst. C.E., M.I.1Mech. who was responsible for the
supervision of all mechanical and elecctrical engineering
work throughout the system. The total staff employed in
this department is normally about 40,000. To Mr. Collett
belonged the distinction of having designed the famous
"Castle" and "King" classes of
locomotives. MORE
Building The Boiler
Section 5
BOILER SHOP
In later years machinery has figured largely in boiler
construction, and the Swindon Boiler shop is thoroughly
and efficiently equipped in this direction. Worthy of
notice is the large hydraulic Flanging press which works
at a pressure of 750 pounds to the square inch.
The flanging of cold copper plates is carried out in this
shop,which was the first to introduce that system.
Electric machines are gradually replacing compressed air
machines in this shop. Boiler plates are cut out and
edges shaped by the oxy-coal gas process.
There is a Boiler Testing Plant by means of which
all boilers are tested, first by hydraulic power and then
under steam at high pressure, supplied from a master
boiler, so that fires are unnecessary in the fireboxes of
the boilers tested. This method permits of careful
examination being made of boiler and firebox while under
steam pressure.More
Building The Wheels Section 6
Steam Locomotive Driving Wheels,Trucks and Motion :
Most non articulated Steam Locomotives have a Driving
Motion made up of Cylinders Pistons, Connecting and
Coupling Rodds, Big Ends
and Slide Bars. The Driving Wheels vary in Size and Nos
from Two in early engines up to 12 in Very Powerfull
Locomotives
built in the USA such as The Big Boy and The Challenger, Articulated Locomotives such as SAR Garratts
can have even more. Smaller Wheels called Trucks Support
the Front end and rear end of most locomotives MORE
Steam Loco MantainenanceSection 7
Periodic Yearly
Maintenance needs to be carried out on
Steam Locomotives, The Boiler Tubes have to be
Washed out and the Interior of the Smoke
Box Cleaned Before every trip The Motion has to be
Lubricated and the Sand Boxes Refilled, and after each
trip before retiring the Loco the Ash Pan and Fire must
be Dropped. During Major Maintenance programs the
Pressure Release Valves have to be tested and new
Pressure Valves Fitted, every 20/30 years the Boiler
Tubes and Super Hearters may be replaced because of
Errosion. The Main Steam Valve
which regualates the ammount of Steam being fed to the
Driving Cylendars must also be Tested and Replaced if
found to be Faulty.

The Great Western Railway
Locomotives 1837--1934
The Development of the
railway locomotive is a Story of ever increasing tractive
power. Whilst comparatively high speeds were attained on
the Great WeStern Railway as far back as the 'forties,
the weights of the trains hauled in those days were but a
fraction of those with which modern locomotives have to
deal. From a few small carriages the train load has grown
to 5 or more 6o-ft. coaches, including dining and kitchen
cars, and having an aggregate weight of 500 tons behind
the tender. Steam
Engine Theory: In its most
basic form, a steam engine is little more than a piston
(much like an automobile piston) that is moved in a
cylinder by the pressure of steam. The cylinder may be
single-acting, meaning that the piston is shoved in one
direction only,relying on the kinetic energy stored in a
flywheel to return it to its original position, or it may
be double-acting, meaning that the piston is pushed back
and forth by alternately admitting steam into opposite
ends of the cylinder. More
. Steam driven Engines
played a Major part in the early developement of
Agriculture and Heavy Industries around the world,
inluding Farming,Timber
Mills, Shipbuilding and Building Construction.
