For the first five miles, the line winds its way through a level country of areca and coconut plantations and then starts the ghat section. The entire line is punctuated by long and eerie tunnels piercing through mountains, numerous bridges over deep ravines and gushing mountain streams, perilous gorges, precarious

The mountain railway was completed only upto Coonoor from Mettupalayam by June 1899 by the Madras Railway Company a British firm under an agreement with the Government of Madras. It was extended to Oootacamund by 1908. There are five stations between Mettupalyam and Coonoor - Kallar, Adderley, Hill Grove, Runnymede, and Kateri. There were also five stations between Coonoor and Ooty-Wellington, Aruvakadu, Ketti, Lovedale and Fernhill - but the last named was closed down some years ago.

The question of electrifying the entire line from Mettupalayam and Coonoor was mooted and an estimate for Rs.31,29,000 was prepared for the purpose as early as in 1908 but the proposal was dropped for reasons not known. Chugging along for almost a century now, on and off, the line is threatened by the authorities with closure but the journey is nonchalant.
