recent one month back heavy floods in mahumabad caused track damaged which leads to cancellation of garibrath,durnoto, gauthami and many more. I think track issue will not araise because KCG- KRNT is a single track and rajadhini & durnoto will pass through the track. I think its better because GNT lacks connectivity to CCT i think only one train from gnt to cct is bhavanagar express
