For the time being we can say it to b an offlink... But ample chances for these trains to get WAP-7s of any of the SER sheds once they get enough of these locos.. However on my 10day visit to my hometown I have spotted 12815 twice with WAP-7s ... once with SRC and another time with TATA... 12876 once with SRC... Many ECoR RFs are also spotting WAP-7s with these 2 trains frequently... So that makes me anticipate that soon the loco links of 12815/16, 12875/76 may get upgraded to P7 of SRC/TATA..
