History of the train:
Kaveri Express-named after the famous river "Cauvery" which passes through Mysore region and crosses at Srirangapatna, was first introduced in the late 70's-Early 80's period as a day time train between Mysore and Bangalore in the erstwhile Meter gauge(MG) era between the 2 cities. The train continued its journey even after the MG was converted to Broad gauge and followed this pattern of RSA as Kaveri-Tippu and Chamundi (Bangalore-Mysore) and opposite as Chamundi-Tippu-Kaveri.
1997-The bangalore-trichy/Madurai link Express was de-linked and Trichy portion extended to Mysore-train left Bangalore at...
more... 5AM to reach Mysore at 7:45AM. The Madurai portion reached Bangalore at 8AM
In 1997 December a Daily special was introduced for winter between Bangalore and chennai. the timings of this train connected the Kaveri Express from Bangalore to Mysore. (7AM departure Bangalore-10AM Arr Mysore and 6Pm from Mysore to reach Bangalore at 9PM). in the next budget Kaveri was extended to Chennai and it lost its Seating accommodation to berths but maintained the same timings in Bangalore Mysore region as before.
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
