CHAPTER-I

1. INTRODUCTION

1.1 Work Study on “The requirement of staff against various activities at Tool room of WRS/Kota” includes as a ‘Crash Study’ for the year 2017-18.

1.2 The foundation stone of Wagon Repair Workshop, Kota was laid in Nin November, 1957 and the shop was commissioned in October, 1960. The Workshop is equipped to undertake POH and ROH of all types of BG wagons on Indian Railway.

1.3 The organizational structure of Workshop is as under:-

CWM (SAG)

Dy.CME ( R) Dy.CME ( P) Dy.CMM

SMM WM Sr.AFA (W&S) ( R)

AWM AWM AWM AEE APO AMM AMM (R ) (G) (M) (W) (W) (X) (G) (SAG)

1.4 Various shops in WRS Kota 1. Body Repair shop 2. Paint shop 3. Machine and Tool Room shop 4. Smithy shop 5. Shop 6. Wheel shop 7. Tank Lifting 8. Box shop. 9. Cartridge Taper Roller Bearing shop (CTRB)

1.5 Tool Room Tool Room acts as service providing shop to other shops of Wagon Repair Workshop Kota.

Staff working in Wagon Repair Workshop, Kota, is classified as Direct Worker, Indirect Worker and Essential Indirect Worker. All the staff of Tool Room are deployed under classification of Essential Indirect Worker.

1.6 Innovations & Improvements (a) Kota workshop developed a rigging device to eliminate manual shunting of wagons from section to fitting section by rigging up a winch using drum and gear box of a condemned EOT crane. This reduced the manpower required for shunting. (b) The shop has designed and fabricated one storage cum transportation pallet for Oxygen and DA gas cylinders. The transportation of this pallet is done using tractor hauled hydraulic carrier. This arrangement is likely to save around 15 to 20 manpower, which were otherwise, engaged daily in transporting the gas cylinders mainly. This will also eliminate Physical strain on the workers and improve the productivity. (c) Riveting process in Kota Workshop has been improved by providing Pneumatic Supporting Device supplied by M/s Mary Enterprises- Kolkata. By using this new device constant pressure is applied on rivet head resulting better formation of head and proper gripping with the mating parts. Thus this improved method appears more reliable. The pneumatic supporting device has been introduced for riveting of 24 mm dia rivet for the fastening of Spring plank with Side frame of Casnub bogie. This process shall also be adopted for other important locations like side bearer assembly and support plate for CBC etc.

(d) Reclamation of Double cups for CTRB: the Double cup of cartridge roller bearing are rejected for various defects viz. flaking spalling Brinelling, pitting, rusting, Electric current damage and Cup broken during overhauling.

The rejection rate is about 12% Kota workshop initiated to attend such rejected double cup having minor defects as per association of American Rail Road (ARR) and collected technical know-how from M/s NEI-Jaipur and successfully repaired 18 Nos and out of these, 08 Nos double cups were sent to M/s NEI-Jaipur for inspection, and were certified OK. The rejection rate is expected to come down by 2%-3%. Net saving is expected to be Rs. 30 lakhs per annum approximately once implemented fully.

GM/WCR and CME/WCR were shown these repaired double cups during their inspection and this attempt by Kota workshop was highly appreciated by them.

(e) Manufacturing of Bolster liners from scrap steel: Manganese steel liners (IS3885) are being extensively used in Casnub Bogie Bolster and side frame. This item has been a stock item but out of stock since last one year due to trade failure. Hence it was decided to manufacture these liners from scrap spring steel flat size 120 x 16 mm x 8 mm (IS3885) released from broken spring top plate. 30 MT spring flats were re-rolled and 17000 liners have been manufactured up to Nov.05 This has resulted:- (i) Saving of approx Rs. Forty thousand per annum (ii) Elimination of the problem of dependency on trade (iii) Improvement in quality of repairs.

3. STAFF POSITION

3.1 Sanctioned strength, men on roll and vacancy position of staff is as under:-

Category S.S. M.O.R. VAC.

Supervisors 207 180 27 Machinist 14 14 0 Driller 16 15 01 Painter 81 68 13 SPS Maker 33 30 03 Turner 45 42 03 Welder 410 345 65 Vehicle Driver 25 18 07 B/Smith 31 27 01 Grinder 04 03 01 Riviter 102 98 04 Furnaceman 06 06 0 EOT Crane Driver 47 43 04 Mat.Cal. 27 21 06 FTR Br 306 287 19 FTR LFT 303 275 28 FTR T/R 12 13 +1 FTR MWT 84 86 +2 FTR Gen. 100 93 07 Total 1646 1484 162 Ministrial staff 128 120 08 Canteen staff 04 04 0 Shunting staff 21 11 10 Group-D 461 477 +16 G.Total 2260 2096 164

It may be seen from the above that the 2260 men are on roll against 2096 sanctioned posts and 164 posts are lying vacant.

3.2 Critical Analysis:- As against sanctioned strength, 164 posts are lying vacant from a long period and no adverse effect is noticed in day to day working of Tool Room. This utilization of above staff as direct worker is fruitful to the overall productivity of workshop and staff also and it may be continued.

Average Utility Percentage of existing staff after giving all necessary time allowances at Tool Room comes to 63 %. Average machine utilization percentage is 96.85%. The both percentage reveals that the less number of staff is sufficient to cope up with the existing workload by improving manpower utility percentage.

The activities carried out at Tool Room are important in nature, but it is noticed by the team during study, some parts/tools which are repaired or manufactured at Tool Room, may be done from outside sources at lower cost. It will be effective to save the valuable man power and revenue both.

The each and every work of Tool Room should be mentioned/noted in log book with timings which makes accountability of work done in Tool Room and how much.

Hardware item like spanner, bolt and other few more items can be procured from outside. Which are easily available in market? This will result in huge saving of man hours.

So, 67% of vacant posts of 164 posts is 109 posts became surplus which should be surrendered.

3.3 Recommendation:- Need based requirement of staff at Tool Room is proposed to 109 are found surplus which should be withdrawn and surrendered immediately.
