 The branch of Civil Engineering which deals with the design, construction and maintenance
of the railway tracks for safe and efficient movements of trains is called Railway Engineering
 Land , water & air have been used by man kind developing the transport modes like Railway,
Highway ,Water way & Airway etc.
History of Railways
 1844 :- First proposal for the construction of railways, in India were submitted to East India company
by Mr. R.Macdonald Stephenson.
 •1849 :- The construction of first experimental line of 160 kms from Calcutta to Mirzapur was
undertaken by East India company.
 Railways were first introduced to India in 1853 from Bombay to Thane
 A British engineer, Robert Maitland Brereton, was responsible for the expansion of the railways from 1857
onwards.
 The Allahabad-Jabalpur branch line of the East Indian Railway had been opened in June 1867
 In 1951 the systems were nationalised as one unit, the Indian Railways, becoming one of the largest networks
in the world.
RAILWAYS ZONES
RAILWAY TRACK / PERMANET WAY
 The combination of rails, fitted on sleepers and resting on ballast & sub grade is called a
permanent way.

RAILS
 The rolled steel sections laid end to end in two parallel lines over sleepers to form a railway track are
known as RAILS.
 Rails are continuous which carry the axial load.
 They are made of high carbon steel to withstand wear and tear.
Axial load
Rail buckling
TYPES OF RAILS
 The rails used in the construction of railway track can be divided into the following three types :
 (1) Double Headed Rails (D.H. Rail)
 (2) Flat Footed Rails (F.F. Rail)
 (3) Bull Headed Rails (B.H. Rail)
1. DOUBLE HEADED RAIL :-
 The rails having their head and foot of same dimensions are known as double headed rail (D.H.).
Double headed
2. FLAT FOOTED RAILS :-
 The rail section having their foot rolled to a flat are known as flat footed rails.(F.F.).
3. BULL HEADED RAIL :-
 The rails sections having their head of more dimension then that of their foot are known as bull
headed rails (B.H.).
Gauge
 Rail gauge is the distance between the inner sides of the two parallel rails that make up a single
railway line.

GAUGE
Types of gauges in india
 There are following type;
Broad Gauge (B.G) - 1676 mm (1.676m)
Meter Gauge (M.G) - 1000 mm (1m)
Narrow Gauge (N.G) - 762mm (0.762m)
Feeder track gauge(L.G)-610mm (0.610m)
.
 Sleepers are members generally laid transverse to the rails, on which the rails are fixed to transfer the loads
from the rails to the ballast and the sub-grade .
 Sleeper are of different materials such as wood ,steel ,cast iron ,R.C.C. ,and pre-stressed concrete.
TYPES OF SLEEPERS

Concrete Sleepers
Ballast
 Ballast is the granular material packed under and around the sleepers and transfer the loads
from sleepers to ballast . It helps to providing elasticity to the track .
 The loss ballast between the two adjacent sleeper is known as ballast crib.
 the process of filling the ballast around the sleeper is called boxing of ballast.

FISH PLATE
Fish plate
In a rail terminology a fish plate splice bar or joint bar is a metal bar that is bolted to the track
the name is derived from a fish a wooden bar with a curved profile use to strengthen a ship a
mast.
FASTENERS JOINT
FASTENERS JOINT
Fasteners joint and fixture are used to connect the rail and
sleepers together in their proper position.
