construction and maintenance of the railway tracks for safe and
efficient movements of trains is called Railway Engineering
Introduction To Railway Engineering

5. Functions of Railway Engineering
 The rails provide the level and continuous surface
 The rails provide a smooth pathway to trains.
 The rails serve as a lateral guide for the running of wheels.
 The rails carry the stresses developed due to vertical loads transmitted
 The rail transmits the heavy load of rolling stock

6. Railway Track Gauge
The gauge is measured as the clear minimum distance between the
running face of to rails.

7. 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..
Sleepers

8. BALLAST
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

9. 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..
Sleepers

10. 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 .

11. Signal and Interlocking
