Thiruvananthapuram division always biased to Kk district of Tamilnadu.For dumping unwanted Kerala circuitous trains are operated from Kk district.
Instead of these 8 circuitous routes trains equal number of Mangalore / konkan via trains have to be operated from KK district .KK district started trains which are run in circuitous Kerala and reenter in to Tamilnadu have to be curtailed in Kerala station itself.
