That doesn't matter, in MAS-MUM line, not evena single train belongs to SR, in case of MAS-SBC-MYS, they have 3 trains , shatabdhi, DD and kaveri express...all these three are not well maintained, even the passengers will not appreciate , if a train is not mainatined well, SWR is well known for its proper maintainance, thats y i am suggesting SR to trasfer the prestigious Brindavan to SWR...........
