Moreover KR doesnt maintains its trains. 10215/6 belongs to KR but it has RSA with NR's Goa Sampark Kranti. Mandovi and Konkan Kanya are run by KR and have RSA with each other. But their maintenance is done by SWR. You can see "KR SWR" written on their coaches meaning that their PM is taken care of by SWR. Members can correct me if I am wrong.
