CLW is presently commissioning IGBT based Traction Converter and Auxiliary Converter in the WAP 7s produced by them. Also they install "Hotel Load" in their WAP 7's in each month.

If "Hotel Loads" are installed in "Wap 7s" then those "P7s" can be used in AC Expresses where the necessity of "Generator Cars" or "EOGs" won't be felt necessary.
