System improvement, Innovation & Achievement of S&T Solapur during 10-11

1.Reliability of Assets:

Total reported signal Incidences during 2010-11: 151 as against target of 167 (Improvement of 9.6% over target &16.6% over 2009-10).

Total SFR failure during 2010-2011: 1663 as against 1960 (Improvement of 15.2% over 2009-10).

Quarter wise performance is as under:

Signal incidence

It can be seen that Reliability of Signalling gear was poor as compared to target & last year during 1st quarter. Afterwards management initiative viz ABC analysis, identification of good & bad stn, daily monitoring of SFR, identification of week maintainerfollowed by continuous training, knowledge up gradation through Confidence Building Course (CBC) at DTC through in house Key Resource Personal (KRP). Regular counseling followed by strict action for bad maintenance & recognition for good Maintainer. Provision of predictive maintenance/monitoring system resulted in substantial & visible improvement in Reliability has been ensured.

2.Human Resource Development

  • Established DTC for Signal & Telecom maintainer at DD by utilizing existing resources & in-house expertise without any extra expenditure.

  • Introduced the Concept of CBC (Confidence building Course) for week maintainer through KRP (key Recourse Personal). Total 414 maintainer including 56 weak maintainer) trained by 18 KRP during the year 10-11.
  • Introduced the concept of recognizing excellent efforts done by maintainer/supervisor. 7Class IV, 19 maintainer & 3 supervisors (Total 29) rewarded by DRM during BOM for ensuring the excellent reliability of signalling & telecom gears.


Introduced the concept of evaluating/monitoring good station/section with SFR failure<1, bad stn/section (Number increased from 22 in April10 to 38 in Feb 11) with SFR failure>4 Number decreased from 12 in April10 to 01 in Feb 11).

Introduced the concept of rewarding staff with excellent reliability (Feb 12excellent stations identifiedwith cumulative average SFR<1 for PI & <4 for RRI
