I am observing that everybody is demanding LHBfication of every Bihar, Bengal bond train. And railway is doing the same thing by converting these trains from ICF racks to LHB racks. But no body is demanding LHBfication of premium trains of WCR/WR bond trains like 12155/56, 12903/04, 12925/26, 12955/26, 12907/08, 12191/92.
