Mujhe bhi kuch baat pata karni hai ke Mumbai to Guwahati ke liye sirf 2 weekly trains hai. 15645/46 via KIR aur 15647/48 via MLDT hai both trains same rake sharing hai to kya LHB coaches both trains ke liye hoga ya phir sirf 15647/48 ke liye. Kya both trains mein se koi bhi ek train ko DBRG extension hone ki koi update ya phir chances hai.
