The Sri Lankan Railways M9 locomotive is a mainline 6 axle Co'Co' diesel electric locomotive built by Alstom (manufacturers code AD 32C) and imported in 2000 for the Sri Lanka Railways.
The locomotives initially had both electrical and mechanical problems, and several were out of service for several years. In 2010 the process of returning the fleet to service began.
Ten units were ordered in 1997 and delivered in 2000, costing 190 million Sri Lankan rupees each[ citation needed ]. By 2010 only 3 were in operation due to technical problems,[ needs update ] [1] Various problems were described including engine malfunction, and problems with the engine control units, [3] as well as the machines requiring modifications for use on curving track. [4] [ unreliable source? ]
The delay in returning the locomotives to service was ascribed to an unaffordability of spare parts, [3] [5] and prohibitive cost of work by foreign firms. [4]
The first of the 7 inoperative locomotives, number 869, was returned to service after 6 years in September 2010, following work by the Arthur C. Clarke Institute for Modern Technologies (ACCIMT) and the Industrial Technology Institute (ITI). [3] [6]
M9s were not allowed on line above Nawalapitiya, Kelani Valley Line and Matale line. [7]
A locomotive or engine is a rail transport vehicle that provides the motive power for a train. If a locomotive is capable of carrying a payload, it is usually rather referred to as a multiple unit, motor coach, railcar or power car;
Brush Traction was a manufacturer and maintainer of railway locomotives in Loughborough, England whose operations have now been merged into the Wabtec company's Doncaster UK operations.
The Northern Ireland Railways DH class was a class of three diesel-hydraulic shunting locomotives obtained in 1969. All three have now been withdrawn, and two have since been rebuilt for work in Sri Lanka.
An electro-diesel locomotive is a type of locomotive that can be powered either from an electricity supply or by using the onboard diesel engine. For the most part, these locomotives are built to serve regional, niche markets with a very specific purpose.
The Indian locomotive class WDM-2 is a class of diesel-electric locomotive that was developed in 1962 by American Locomotive Company (ALCO) for Indian Railways. The model name stands for broad gauge (W), Diesel (D), Mixed traffic (M) engine, 2nd generation (2). They entered service in 1962. A total of more than 2,700 WDM-2 was built at ALCO and Banaras Locomotive Works, Varanasi between 1962 and 1998, which made them the most numerous class of mainline diesel locomotive until its successor the WDM-3A.
The ALCO DL560C is a series of diesel-electric locomotive with AC electric transmission designed by the American Locomotive Company and produced under license by Banaras Locomotive Works (BLW) Varanasi, India for Indian Railways as their classes WDM-2, WDM-3A/2C, WDM-3D and WDG-3A for operation in India. The locomotive is fitted with a 16-cylinder ALCO 251 B,C diesel engine. In the early 1960s Indian Railways needed a reliable diesel workhorse to gradually replace its steam locomotive fleet. Equal numbers of ALCO's DL560C and EMD's G16 were chosen for trials. More locomotives of each of these were purchased for more trials. Indian Railways was keen on producing these locomotives in the country rather than depending on imports. EMD did not agree for a Transfer-of-Technology, while ALCO did. Thus ALCO DL560C was chosen for the job due to its easy maintenance, reliability and simple operation. And from then on vast numbers of this loco in different configurations have been produced and remain the main diesel traction power of Indian Railways.
The Sri Lanka Railway Department is Sri Lanka's railway owner and primary operator. As part of the Sri Lankan government, it is overseen by the Ministry of Transport. Founded in 1858 as the Ceylon Government Railway, it operates the nation's railways and links Colombo with other population centres and tourist destinations.
Advanced steam technology reflects an approach to the technical development of the steam engine intended for a wider variety of applications than has recently been the case. Particular attention has been given to endemic problems that led to the demise of steam power in small- to medium-scale commercial applications: excessive pollution, maintenance costs, labour-intensive operation, low power/weight ratio, and low overall thermal efficiency; where steam power has generally now been superseded by the internal combustion engine or by electrical power drawn from an electrical grid. The only steam installations that are in widespread use are the highly efficient thermal power plants used for generating electricity on a large scale. In contrast, the proposed steam engines may be for stationary, road, rail or marine use.
The Prima Diesel-electric locomotives are a class of medium and heavy, four- and six-axle, passenger and freight mainline locomotives. They have been built both to 1,435 mm standard and 1,668 mm broad gauges, and find use in the Middle East, Europe and North America. Alstom is the primary designer in cooperation with both General Motors and Siemens.
The M1 locomotive was a class of locomotives, used by Sri Lanka Railways, imported from 1953, and manufactured by Brush Bagnall Traction.
The RK 215 is a line of diesel engines built by MAN. The RK 215 series is a large four-stroke diesel engine that has an 11-liter displacement per cylinder.
Locomotives and train sets of Sri Lanka Railways consist mostly of diesel locomotives and multiple units. Steam locomotives are no longer used, except on heritage trains, such as the Viceroy Special.
The northern line is a railway line in Sri Lanka. Branching off the Main Line at Polgahawela Junction the line heads north through North Western, North Central and Northern provinces before terminating at the northern port of Kankesanthurai. The line is 339 kilometres (211 mi) long and has 55 stations between Polgahawela Junction and Vavuniya. It is the longest railway line in Sri Lanka. The line opened in 1894. Major cities served by the line include Kurunegala, Anuradhapura, Vavuniya and Jaffna. The popular Yal Devi service operates on the line. The line was severely affected by the civil war and no services operated north of Vavuniya after 1990. Reconstruction of this section of the line commenced following the end of the civil war in 2009 and was fully completed in early 2015.
The Batticaloa line is a railway line in Sri Lanka. Branching off the Northern line at Maho Junction, the line heads east through North Central Province and south-easterly through Eastern Province before terminating at the eastern city of Batticaloa. The line is 212 kilometres (132 mi) long and has 31 stations. The line opened in 1928. There were no services on the Polonnaruwa-Batticaloa stretch of the line between 31 October 1996 and 12 April 2003 due to the civil war. The Udaya Devi service operates on the line.
The Main Line is a major railway line in the rail network of Sri Lanka and considered by many to be one of the most scenic train journeys in all of Asia. The line begins at Colombo Fort and winds through the Sri Lankan hill country to reach Badulla.
The Sri Lanka Railways Class M2 is a class of diesel-electric locomotive that was developed in 1954 by General Motors Diesel, Canada, and Electro-Motive Division, USA. This is considered one of the most successful locomotives in Sri Lanka.
The Sri Lanka Railways Class M5 is a type of diesel-electric locomotive. The class was ordered to strengthen the diesel locomotive fleet of Sri Lanka Railways.
The Sri Lanka Railways Class W1 is a class of Sri Lankan diesel hydraulic locomotive that was built by Rheinstahl Henschel in 1969. A total of 45 W1s were built and imported. This is the first diesel-hydraulic locomotive which ran on Sri Lankan rail.
The Sri Lanka Railways W2 is a class of diesel-hydraulic locomotives built by LEW Hennigsdorf for Sri Lanka Railways.
The Indian locomotive class WDM-3D is a class of diesel-electric locomotive that was developed in 2003 by Banaras Locomotive Works (BLW), Varanasi for Indian Railways. The model name stands for broad gauge (W), Diesel (D), Mixed traffic (M) engine with 3300 horsepower (3D). The engine is classified WDM-3D though it outputs only 3300 hp and not 3400 hp as the name should suggest. They entered service in 2003. A total of 590+ WDM-3D were built at Banaras Locomotive Works (BLW), Varanasi between 2003 and 2016.
