WAG-9 is a type of electric locomotive used in India. It is the most powerful freight locomotive in Indian Railways' fleet. It is very similar to WAP-7; the only major difference being the gear ratio which makes it suitable for heavy freight operations. In November 1998, Chittaranjan Locomotive Works (CLW) started producing these with indigenous components. The first one, 'Navyug' (translated, 'New Era'), was flagged off on November 14. Like the WAP-5 units, they have GTO thyristor converters and 3-phase asynchronous motors.
Newer versions starting from WAG-9 31248 feature full IGBT traction...

Sir, I didn't get your point that what are you asking.
In your first pic, the loco number is very clear and LGD sticker is clearly visible (If you aware of the LGD sticker, you can recognize it)

Sir, to be more clear, WAG9 is nor similar to WAP7, but WAP7 is derived from WAG9 and with different gear ratio.
The loco 31248 with IGBT, is also based @ LGD.
Not only WAG9i or WAG9Hi, even WAP7's which are being produced latest are almost IGBT locos only, including WDP4D's also.

Also, there were some braking issues in WAP7. Because of it, the bogie of WAP7 has been changed to the same bogie of WAG7. That is, the bogie of WAG7 is used for WAP7.
