HWH needs them to run HWH Rajdhani at 160 km/h in near future. IR is planning to do the same.
Suitable infra should be provided to TKD ELS so that WAP5 locos could be homed there. It will help reducing the load on GZB.
In the south, LGD should get them first due to two planned high speed corridors : NGP-SC and MAS-SC.
