Indian Railways could achieve the objective of TOT ( Transfer of Technology) of 3-phase Traction Technology in a very short period  only because of close co-operation with ADtranz and Indian Railways. The scope of TOT included  all the sub-systems. Out of these, 5 major equipments were identified which constitute about 67% of the loco cost. These are (i) Traction Converter; (ii) Auxiliary Converter; (iii) Control Electronics; (iv) Traction Motor; (5) Traction Transformer. CLW transferred technology of these items to Indian Industries  who were “ partners of Indian  Railways” to emphasize  the needs of synergic  relationship. After selecting the most capable partners through open tender, extensive  help was extended to train manpower, set up necessary infrastructure and development of necessary tools and plants and testing facilities. The Indian partners were also advised to attempt indigenisation at the component level during initial stage itself i.e. buying/procuring these components from the OEM instead of ADtranz. It was due to these efforts that all major equipmentS of locomotives  haVE since been developed and supplied at less than 40% of the  imported cost in record time of less than 3 years.

 For non-Adtranz components of the locomotives 

                        Indian Railways contracted ADtranz's sub-contractors and persuaded them to have a tie up with the Indian Firms and Indian TOT  Partners. This attempt was successful and it helped further to bring down the cost of production. CLW  has prepared procurement specification of all ADtranz components. Today CLW has achieved indigenisation  over 50% of expect to achieve 100 % by  March 2003, when the cost of loco will be brought down to about Rs.8 crore against the present cost of    Rs. 13.65 crore.

                         First CLW built indigenous loco ( NAVYUG) was rolled out on 14.11.1998. Thereafter CLW has achieved serialisation of WAG-9 production and has turned out 8 WAG-9s, which is the testimony on CLW’s  prowess to assimilate the ‘State-of-the Art’ technology, the following firsts are turned out in 1999-2000:-

                         The requirement of Indian Railways projected during 2000-01 are 25, 3-phase locomotives and the production of conventional locomotives ( non 3-phase) will be gradually tapered off. In order to ensure the quality of items supplied by  trade, CLW is considering only ISO 9000 certified vendor’s for its products.
