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).

The Railway Board had paid Rs.762.61 crores upto March 1997 for supply of the locomotives, maintenance spares and for transfer of technology.
