The gauge conversion between Trichy and Tanjore extended Trichy Express(16231/32) to Tanjore in 1999. in 2001 Bangalore Madurai Express(16731/32) was extended to Tuticorin. The timings of 16231 was changed to reach Bangalore at 6:15 and leave at 6:30 to Mysore and was followed by Kaveri at 7AM. the Tuticorin Express was speeded up to reach Bangalore at 6:45AM and it left Bangalore to tuticorin at 9:45PM
Around 2003 16731/32 was extended to Mysore and timings up to Bangalore remained the same. The erstwhile slot of 16231/32 remaining vacant to Mysore Kaveri was allotted the timings for Bangalore-Mysore strech. Since 16732 occupied Kaveri timings on return too Kaveri was rescheduled to leave Mysore at 8PM the timings it follows even today
