AC 3 phase locomotives procured at the cost of Rs.762.61 crores failed to render satisfactory performance due to manufacturing defects
Out of 30 locomotives, 23 locomotives put in service (10 #WAP5 and 13 #WAG9) failed during commissioning and trials and large scale modifications were required, 7 locomotives are still in the assembly bay at #CLW (November 1997). In December 1996, RSDO listed more than 30 defects in these locomotives and asked for immediate rectification/ modification. Unsatisfactory performance of WAP-5/ WAG-9 locomotives still continues. The main problems being encountered with freight locomotives (November 1997) are wheel skidding (31 cases), failure of GTO valve set (8 cases), power supply card failures (12 cases), machine room blower seizure (19 cases) and

oil leakage from main converter (12 cases). Similarly, WAP-5 locomotives are suffering from wheel defects, oil cooler defects, pantograph defects and oil leakage from radiator. Thus, even after one year of their receipt in India, the locomotives have failed to render satisfactory performance due to several manufacturing defects. The Railway Board had paid Rs.762.61 crores upto March 1997 for supply of the locomotives, maintenance spares and for transfer of technology.

import of high speed coach was not justified for the following reasons:
(a) RDSO had covered much ground and was confident of achieving improvements in coach designs to suit specific requirements of Indian Railways. The Minister had also felt in June 1992 that "all requirements can be met by going ahead with our plans for upgrading the ICF coaches", but asked for a review by the full Board in view of the insistence of the former CRB and MM on import.
(b) Following that directive
...

of the Minister, the considered view of the Railway Board (18/ 19 June 1992) was that the present cost of import of the coach would be too high (Rs.5 crores per coach against Rs.0.50 crore per indigenous coach) for the benefits likely to be derived.
(c) The present track standard does not permit running of longer coaches and would need additional investment on the track to accommodate such coaches.
(d) In fact, with the help of RDSO and experts of UNDP, RCF succeeded in rolling out in 1994-95 a prototype of high speed coach which was fit to run at 160 kmph.
ii) After marathon search for a "state of art" coach technology for 9 years, what Railways finally opted for was not a complete coach technology but a part of it. As per finalised contract, 21 AC Chair cars would be supplied without antiskid devices restricting the speed potential to 160 kmph only. Similarly, 3 generator-cum-brakevans would be supplied without power generation equipments, viz. diesel engines, alternators, rectifiers and control equipments. Thus, these 24 coaches cannot be put in service even on Shatabdi routes on their receipt in India. Formation of two full rakes for Rajdhani routes would not be possible at all in the absence of AC first class and AC sleeper coaches to complete the formation. The import of 'state of art' coach technology, therefore, would not bring any immediate benefit to the Railways.

    These days, every other day, we are getting requests from members to allow email login to their FB-based IRI account. 10 years ago, we had given the option for users to login through FaceBook - in retrospect, this was a mistake.
