Nilgiri Mountain Railway locomotives

The Nilgiri Mountain Rly is a metre gauge line 28 miles long. It runs from Mettupalaiyam to the hill station of Udagamandalam (previously Ootacamund, still universally known as Ooty) in the Nilgiri mountains of southern India. A journey takes five hours. The railway has two distinct sections. Most of the line from Mettupalaiyam to Coonor is fitted with the Abt rack system and is wholly steam operated by X class 0-8-2Ts. It is the only rack railway in India. The section from Coonor to Ooty is a normal adhesion line and is worked by diesels. Coonor station is a terminus, so trains to or from Ooty have to reverse in and out. Locos are always at the downhill end of trains. In all, 21 X class locos have been built - or are on order, as Indian Rlys are building four new ones!! Most of the 12 earlier surviving locos (37384 - 395) I saw have been converted to burn oil, apart from two in preservation. Here are photos of five of them, plus the two new locos (37396 - 397) delivered at the time of my visit. I did not see 37387, 388 or 393 - 395, and do not know their status.
