SBC BGM is Special Tatkal SF train so speed will be more only compared to YPR UBL exp.. Also the train has given good TT is such TT given to all trains then all will run same no doubt. It's matter of TT not train I think.. And UBL YPR route is 110 kmph i think better they upgrade it to 130 kmph and if possible 160 kmph also better. Now it's good timing MOSR can get approved this upgrade later it takes time for official approvals if MOSR changes..
