No you check for return link is LGD WAP-7 . And since SWR contains less 55-60 WAP-7 and LGD contains 150+ locomotives so I have seen many Bengaluru bound trains like Bengaluru-Nanded express , Karnataka Sampark Kranti , Karnataka Express , Bengaluru Rajdhani runs with Lallaguda based WAP-7 even sometimes I have seen these trains running with offlink like RPM WAP-7,AJNI WAP-7 or KYN WAP-7 but in these LGD WAP-7 is used maximum so I don't know whether it is offlink or not . So please verify ones
