I also say this trains is a combination to 2 to 4 small distance trains......all the 4 trains clubed togeather and make longer routes...
many are such trains in many zones in form of MYS-SNSI and MYS-BSB,Kalingutkal,KOP-HYB,Deekshabhoomi
agree BZA-RC needs shorter connection but who ever the zones is either SCr or SWR says own reasons when asked via GNT....
