Adventure with Andysam: My coonoor visit

The NMR track is 1,000 mm (3 ft 3 ³⁄₈ in) gauge and the railway is isolated from other metre gauge lines.
Between Mettupalayam and Coonoor, the line uses the Abt rack and pinion system to climb the steep gradient. On this rack section trains are operated by 'X' Class steam rack locomotives manufactured by the Swiss Locomotive and Machine Works of Winterthur in Switzerland. These steam locomotives can be used on any part of the line (either with or without the rack section),but the newer diesel locomotives can operate on the entire section, between Mettupalayam and Udagamandalam.This signals the beginning of the process to phase out the coal-fired vintage Swiss engines that took scores of passengers on the rack and pinion track to Coonoor and Udhagamandalam, covering 41.8 km, 108 curves, 16 tunnels and 250 bridges
Hence, the Southern Railway decided to replace the coal-fired locomotives. The work was entrusted to Golden Rock Workshop of Southern Railway at Tiruchirapalli. Each of the new engines weighs a little over 50 tonnes and cost Rs.10 crore.
The new engine has been provided with pilot and primary burners with separate tanks to hold about 850 litres of diesel and 2,250 litres of furnace oil. The hauling capacity of this new engine is 97.6 tonnes and it can run at a speed of 30 km an hour in plains and at 15 km an hour on a gradient.
Officials hoped to put the engine to use by Sunday on the Mettuppalayam–Coonoor section. The arrival of the new engines raises hopes of eliminating the disruption in service that occurred frequently over the last two years.
For long, the X Class locomotives manufactured by Swiss Locomotive and Machine Works of Winterthur in Switzerland lent that distinct charm to NMR. These locomotives are six to eight decades old, railway officials said
The steam locomotives are always marshalled at the downhill (Mettupalayam) end of the train. The average gradient in this rack section is 1 in 24.5 (4.08%), with a maximum of 1 in 12 (8.33%).

Between Coonoor and Udagamandalam the train is operated by a YDM4 diesel locomotive using conventional rail adhesion principles. On this section the locomotive is always at the Coonoor end of the train as although the line is not steep enough to need a rack rail, the ruling gradient out of Coonoor is still very steep at 1 in 25 (4%).

Steam Locomotive

As of 2007, there is one train a day over the rack section, which starts from Mettupalayam at 07:10 and reaches Ooty at noon. The return train starts from Ooty at 15:00, and reaches Mettupalayam at 18:35. The train is scheduled to connect to the Nilgiri Express, which travels from Mettupalayam to Chennai via Coimbatore. A summer special service is also run during the months of April and May, starting from Mettupalayam at 09:30 and from Ooty at 12:15. Between Coonoor and Udagamandalam, there are four daily trains each way.

NMR issues old style tickets, keeping in line with the World Heritage Site status.

Even though the NMR stations have networked computerised ticketing systems for onward journeys, it still issues Edmondson style manual tickets for the Ooty-Mettupalayam journey to preserve the 'World Heritage Site' status of the railway. However, ticket booking is similar to other conventional trains and can also be done via the Indian Railways' website.^[4] It is advisable to book tickets for this railway in advance, especially during peak season.
The majority of repairs to the locomotives are carried out at the Coonoor shed but many of the steam locomotives have been rebuilt at the Golden Rock Workshops. Carriages are repaired at Mettupalayam but, like the locomotives, are taken to one of the big railway workshops for major work. Due to its popularity, a number of passengers using the NMR have requested that the Southern Railways convert the section from Coonoor to Udagamandalam to steam locomotive^{[citation needed]}, extending the present steam traction between Mettupalayam and Coonoor.

Mettupalayam Station

Mettupalayam(Coimbatore) - 0 km (0 mi), 1,069 ft (325.8 m) above sea level - Junction with the 5 ft 6 in (1,676 mm) (Indian Gauge) line from Coimbatore city railway station. Passengers cross the platform to board the Nilagiri Passenger train (NMR). There is a small locomotive shed here and also the carriage workshops for the line.

Leaving Mettupalayum, the line is adhesion worked and actually drops for a short distance before crossing the Bhavani River, after which it starts to climb gently.

Kallar Station

Kallar - 8 km (5 mi), 1,260 ft (384 m) - Closed as a passenger station, this is where the rack rail begins. As the train leaves the station, the gradient is 1 in 12 (8.33%).

Adderly Station

Adderly - 13 km (8.1 mi), 2,390 ft (728.5 m) - Closed as a passenger station but is still a water stop.

Hillgrove Station

Hillgrove - 18 km (11.2 mi), 3,580 ft (1,091.2 m) - Block post and water stop, also has refreshments for passengers.

Runneymede Station

Runneymede - 21 km (13 mi), 4,612 ft (1,405.7 m) - Closed as a passenger station but is still a water stop.

Kateri Road Station

Kateri Road - 25 km (15.5 mi), 5,070 ft (1,545.3 m) - Closed as a passenger station, trains do not stop here.

Coonoor Station

Coonoor - 28 km (17.4 mi), 5,616 ft (1,711.8 m) - main intermediate station on the line at site of the locomotive workshops as well as the top end of the rack rail. Trains must reverse a short distance before continuing their climb to Ooty. It is normal for the locomotive to be changed here with diesel traction, being normal for all trains to Ooty.
