well convenience is a relative thing...pnbe hwh jan shatabdi is one of the longest jan shatabdi in indian railways...it is an excellent option for travellers who intend to reach hwh during day...not all like overnight travel...excellent patronage too(though more by current and unreserved passengers than the reserved ones). for me to catch a train even at 8 am would be inconvenient...but then might be useful for many...i jus wanted to confirm the cause for calling it weird...
