Yes even I too heard SCR tone long back hope still they might be using same one.. But I heard same SCR tone at Gadag jn in MG time but later changed to some other one and now I don't know they are using or removed same lime how they did at BAY jn cause both lie in same division so chances are their In Gadag to without tone announcements it seems silly one but very important and memorable for me to listen those different zones tones whigh I heard in my childhood it takes me back to my childhood..
