I never knew WAP-5 are short of EOG...
Nevertheless, P-5 got this feature in 2018 (past various challenge faced & rectified in P-7 since 2007 development stage). This is the sole reason for HOG P-5 to be of lesser count (not sure but maybe HOG P-5 are 6000HP)!!
EMD got this in 2019 and can be seen in Kathgodam Shatabdi at YouTube!!
