Today satabdi exp covers BHP-BWN section in 38 min......satabdi exp did this job in regular basis and reach BWN within 36-39 min with more than 82 kmph avg speed with LHB coach.....so why other superfast exp cannot do this job regular basis??????
....
I noticed that saraighat exp and darjelling mail do this sometime but not regular......IR provide huge slack in this section for all train......
