I think the WDM3A locos which were rebuilt by DMW, Patiala are 3300 HP power-packs. Right?
Not sure how many of them were rebuilt!

---

Yes, both the rebuilt WDM3A's and the last batch that were manufactured were of 3300HP. Between 2012-14, 150 locos were rebuilt.
The WDM2G is still under production right? Probably the most promising innovation from DLW for now.

---

I think the prototype, WDM2G 80000, is still undergoing tests/trials.
Similar innovations can be tried on EMD platform as well.

In fact, what is really impressive about the EMD class is that the wheel slipping can actually be controlled using radar that senses the linear speed of the loco which is taken as the reference for comparison. In other locos, during slip, corrective action is taken (like reducing current supplied to the motors) for re-adhesion.
Hence, the uncontrolled spin of the wheels is prevented in EMD's. Sanding is automatically invoked whenever an axle slips.
GM's technology after all _/\_
