dont get lured by GNWL from LPI and BMT for journey beyond ...since SC is under RLWL , people book GNWL or tatkal and thier ticket end up in RAC or WL , this train empties itslef at SC and hence RLWL has far more chances of confirmation for onward journey ...also charting time for LPI/BMT and SC are different with huge difference in time , one can take a chance of booking in GNWL , if it doesnt go thru , then book in RLWL ex SC ...
