I have seen Gulbarga station SB having Urdu when it was Gulbarga in 2014 but now after name change to Kalaburagi the Urdu naming lately implemented as Kalaburagi with permission from Divisional incharge.. This Hyderabad karnataka region was under Hyderabad Nizam Province so which is taken into Karnataka after state unification froming new state Karnataka so Urdu is long ago connected to these places by history like how some North Indian cities are connected..
