RAILWAY ENGINEERING
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
THE DIVISION IS HEADED BY DIVISIONAL RAILWAY MANAGER. (Sushree .Archana Joshi)
DRM CONTROL ALL DIVISION. THE KOTA DIVISION COVERS TOTAL

CONTENTS
Ballast is the granular material usually broken stone or bricks single and kanker, gravel and sand placed and packed and around the sleeper to transmit Load from sleeper to formation Layer.Size = 20mm – 65mm
BALLAST
RAILS The rolled steel sections laid
end to end in two parallel lines
over sleepers to form a railway
track are known as 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)
TYPES OF RAILS :-
The rails having their head and foot of
same dimensions are known as double
headed rail (D.H.).
1. DOUBLE HEADED RAIL :-
The rail section having their foot
rolled to a flat are known as
flat footed rails.
2. FLAT FOOTED RAILS :-
The rails sections having their head of
more dimension then that of their foot
are known as bull headed rails (B.H.).

Sleepers
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 subgrade.

POINT OF CROSSING
Point , crossing , turnout , cross-overs and such related terms are arrangement by which different routes either parallel are connected and offered the means for terms to move from one route to another route is called POINT OF CROSSING .
