culprit for shipra's poor maintenance is its RSA with PNBE express. Give it dedicated rake and see the differences.
BTW INDB-Pune has good rake and it is maintened at indore.
Its the RSA which causes bad shape of rake. One more example for this is HBJ INDB intercity it used to have very neat clean rake . Now thanks to its RSA with HBJ Dahod passanger it is not so great.Another train which is suffering becasuse of RSA is indrayani exp which has RSA with Pune Sur intercity
