3.  Objectives of maintenance of railway track
The strength of track structure goes on reducing due
to high speed of trains, heavy axel loads and repetition
of loads.
The track structure is subjected to other deteriorating
effects like rain water, action sun and wind. the wear
and tear of rail and rolling stocks is bound to take
place.
The track structure has to bear so many other
curvatures, speed and load effects, particularly on
curves, point and crossings.

4.  Advantages of Good maintenance
The life o both track as well as of rolling stock increases.
The journey becomes easy and comfortable.
Increase in safety.
Saving in operating costs as fuel consumption is less.
Safety of passengers and goods encourages more and more
use of railways.
Higher speed of trains is achieved.

5.  Causes of Maintenance :
The strength of track structures goes on reducing due
to high speed of trains, heavy axel loads and repetition
of loads.
The track structure is subjected to other deteriorating
effects like rain water, action of sun and wind.
The wear and tear of rails and rolling stock is bound to
take place.
The track structure has to bear so many other
curvatures, speed and load effects, particularly on
curves, points and crossings.

6.  Types of Maintenance :
 The maintenance of railway track can be devided into two
parts :
1. Daily Maintenance
2. Periodical Maintenance
1. Daily Maintenance:
Daily maintenance is carried out by the full time staff
maintained throughout the year. The use of maintenance
gauge. All along the railway track, is made. The railway track
is divided into suitable sections 5 to 6 km length.

7. Works carried out by the maintenance gauge are,
 To check the bolts of fish plates and tighten it if necessary
 To check the rail gauge
 To check the joints.
 To check the fittings of sleepers and rails.
2.Periodical maintenance :
periodic maintenance is carried out after an interval of 2
to 3 years. during periodic maintenance the gauge, levels,
alignment, points and crossings etc. are thoroghly checked ,
the defects are detected , the causes are determined and
remedial measures are taken.

8. The periodic maintenance includes,
1. Leveling of rails
2. Track alighment
3. Gauuge
4. Proper drainage
5. Track components
6. Bridge and its approches
7. Rolling stock
8. Points and crossingges
9. Level crossings
10. tunnels

9.  Tools for railway track maintenance and their functions :
o Hand tools :
 beater cum pickaxe

10. Rail gauge
To check the gauge of tracks.

11. Spanneer
To tighten or loose fish plate bolts.

12. Powrah
To handle the ballast..

13. Jim crow
To bend the rails

14. Sleepers tongs
To lift up the sleepers

15. Auger
To drill holes pikes

16. Shovel
To handle the ballast

17. Spirit level
To check cross levels of rails.

18. Craw bar
To correct the track alignment

19. Claw bar
To remove dog spiikes out of sleepers

20.  mechanical tools :
Lifting jacks
To lift large portion of track expeditely

21. Track liners
To correct the considerable variations in alignment
effectively

22. Electric-tie tampers
To pack ballast under sleepers
