I think its better to reintroduce the ICF rake for BZA - OGL - GDR - OGL - BZA (67298/80 and 67279/97) instead of MEMU passenger. It having some problems like lack of Toilets and Luggage. As per the scheduled train rested for 30min at OGL. In that any body need to go to Toilets, that's OK no problem. But what they do in the running train. For Ladies its a big problem.....
I think some MEMU having Toilets facility. At-least that train will run in this long journey. Total journey in this, from BZA to GDR to BZA is 16hr to 17hr..
