DOs and Don’ts OF LWR FOR PWM, MATES & KEYMAN

DOs

1. Check and carry LWR/CWR equipment daily. Each Gang mate/ PWM should keep two Sets of joggled fishplates, 2 clamps, one rail thermometer, special 1m long fish-plates, rail closure pieces, one straight edge and one feeler gauge. The thermometer should be regularly checked with that of standard thermometer kept

in PWI's office.

2. Know the td of your section/panels.

3. Keep the ballast section full and in compacted condition particularly in cribs and shoulders. Deficiency in ballast shall be brought to the notice of PWI.

4. Keep close watch on pedestrian and cattle crossings, where the ballast is always disturbed. Make up ballast deficiency promptly.

5. Get your SEJs oiled and greased once in a fortnight.

6. Check the gaps of SEJ at extremes of temperatures.

7. Train men in detecting buckling, rail fractures etc. and protection of the trains in such cases.

8. Keep the patrolling equipments always handy and start patrolling of track as soon as temperature exceeds td + 20ᴼC. This is marked on the thermometer in red. 

9. Commence patrolling as per laid down schedule for the prescribed periods.

10. Keep sharp look out for severe alignment defects in summer. Protect the trains and report to supervisors.

11. Keep the anchors wherever provided always butting against the sleepers. 

12. Renew fittings only on one sleeper at a time.

13. Ensure that fittings are tightly fitted at proper places at all times.

14. Pack loose sleepers without lifting or opening track in summer.

15. Attend only one or two sleepers at a time for adjusting fittings while removing a kink.

16. Confine essential maintenance to period when the temperature is below  td+10ᴼ C.

17. Impose speed restriction if temperature exceeds td + 20ᴼ C during consolidation period.

18. Pay special attention to SEJs, breathing lengths, curves, approaches to level crossings, unballasted bridges, horizontal and vertical curves.

19. Keep the rail thermometer with proper markings with limiting temperature ranges thereon in proper working order. Learn the limits of temperature restrictions as marked on thermometers for various operations.

20. Check that reference posts at SEJ and at centre of LWR/CWR are correctly maintained.

21. Pay special attention for crib and shoulder packing of ballast on CST-9 road.

22. Learn the six items

 (i) missing and loose fastenings, 

(ii) shortage of ballast, 

(iii)misalignment

(iv) slewing

 (v) Lifting 

(vi) improper packing, about which you should be very careful to avoid buckling.

23. Learn what to do when there is buckling or fracture in the track.

24. Ensure that all bridges and its approaches have all fittings at all times and are

regularly tightened.

sleepers at a time.

10. Do not allow loose, missing or ineffective fastenings to remain in track.

11. Do not neglect checking and attending to the breathing lengths of LWR/CWR in a fortnight.

12. Do not lift track by more than 50 mm even if temperature is within td.
