Wellington is a town in The Nilgiris District in the Indian state of Tamil Nadu. Wellington is home to The Defence Services Staff College (DSSC), a premier tri-service training establishment that imparts training to middle level officers of the three wings of the Indian Armed Forces, friendly foreign countries and various Indian Civil Service departments. The Nilgiri Passenger train passes through Wellington, which has a railway station. The college has a colourful past and traces its lineage to 1905 when it was set up at Devlali. In 1907 it shifted to Quetta, now in Pakistan, under the British Indian Army.
