This train is not convenient one for Kerala to Mumbai passengers. This acts as a link train from Kerala to TN/ AP, TN/ AP to Mumbai, KA to Mumbai.
Can some experts throw some light on possibility of diverting the train from SA via SBC/YPR/KJM-DMM-GTL route? For the missing link, TVC/ ERS-HYB via TPTY-GTL-MBNR can be started. For Mumbai-RU passengers, an additional train to Chennai can be added in the slot vacant. I feel atleast 2 rakes can become free.
