A worker at LKO told me that Begumpura is the only train[apart from dbrt raj] than can be trusted on the BSB-LKO stretch. Himgiri jaisi traine toh late hoti hain par Begumpura sahi aati hain.
I have spotted begumpura many times at LKO, arriving dot on time usually, Loco varies from either P-7 or P-4.
