The UM12C is a type of diesel-electric locomotive manufactured by GE for Southeast Asian rail operators. It is currently in service with the State Railway of Thailand. It was also operated by the Manila Railroad Company and the Philippine National Railways from 1956 until 1999. [5] While the units for both companies feature a shovelnose layout, the MRR locomotives were single-ended and had a cowl unit cab, the SRT locomotives are double-ended cab forward units.
The Manila Railroad Company (MRR) announced the dieselization of its locomotive fleet in 1954. GE Transportation was selected as the supplier of diesel-electric locomotives. The agency bought fifty units in which thirty were streamlined mainline locomotives and twenty were switchers. Twenty of these were the UM12C road switcher model MRR 2000 class. These were some of the first locomotives to feature the cowl unit design. [6]
The locomotives were introduced to the MRR in 1956. Along with the cab unit 1000 class, they formed the mainline locomotive fleet in Luzon until the late 1970s and the early 1980s. Starting in 1973, a newer GE Universal Series type numbered the PNR 900 class was introduced on mainline passenger services. Due to its popularity on services such as the Amianan Express and the Bicol Express, it eventually replaced the 1000 and 2000 classes from passenger service. The 2000 class continued service until January 1999 and the remaining units were immediately scrapped. [4]
The State Railway of Thailand purchased 50 units of a meter gauge version of the UM12C. Unlike the Philippine version, it features a dual cab layout with a cab forward design. As of 2015, 45 units remain in service with the SRT.
The Philippine National Railways (PNR) is a state-owned railway company in the Philippines which operates one commuter rail service between Laguna and Quezon, and local services between Sipocot, Naga and Legazpi in the Bicol Region. It is an attached agency of the Department of Transportation.
A cowl unit is a diesel locomotive with full-width, enclosing bodywork, similar in appearance to the cab unit-style of earlier locomotives, such as the EMD F-units of the 1940s and 1950s. The term cowl unit is of North American origin, although similarly-styled locomotives exist elsewhere.
A road switcher locomotive is a type of railroad locomotive designed to both haul railcars in mainline service and shunt them in railroad yards. Both type and term are North American in origin, although similar types have been used elsewhere.
The State Railway of Thailand (SRT) is the state-owned rail operator under the jurisdiction of the Ministry of Transport in Thailand.
Dieselisation is the process of equipping vehicles with a diesel engine or diesel engines.
The GE C40-8W is a 6-axle diesel-electric locomotive built by GE Transportation Systems from 1989 to 1994. Often referred to as the Dash light series, it is part of the GE Dash 8 Series of freight locomotives. This locomotive model is distinguished from the predecessor Dash 8-40C by the addition of a newer "wide" or "safety" cab. A cowl-bodied version of this locomotive, built only for the Canadian market, was the GE Dash 8-40CM.
Rail transport plays a crucial role in connecting various regions of Thailand, transporting both goods and passengers through a range of transportation options that include inter-city and commuter rail, mass rapid transit, monorails, and airport rail links. The State Railway of Thailand (SRT) operates a network of intercity railways spanning 4,845.1 kilometers, covering 47 provinces across the country. SRT is committed to developing railway lands through its subsidiary, SRT Asset (SRTA), which focuses on transit-oriented development (TOD) initiatives. The Krung Thep Aphiwat Central Terminal in Bangkok serves as the primary transportation hub for rail transport in Thailand, connecting various types of rail transportation throughout the country. It covers an area of 274,192 square meters, making it the largest railway station in Southeast Asia, and is situated in a new central business district (CBD) that is currently being developed.
The Dash 8 Series is a line of diesel-electric freight locomotives built by GE Transportation. It replaced the Dash 7 Series in the mid-1980s, and was superseded by the Dash 9 Series for freight usage and the Genesis Series for passenger usage in the mid-1990s.
Yommarat railway halt is a railway halt in Bangkok. It is owned and operated by State Railway of Thailand and serves the Northern, Northeastern, and Southern Lines. It is on Sawankhalok Road in Thung Phaya Thai, Ratchathewi District, Bangkok, to the north of Yommarat level-crossing. The trains that stop at this station are only commuter services and some ordinary services. Not far from the halt is Uruphong Halt, a separate halt for the Eastern Line. Yommarat was refurbished since 2017 and was used as an access point for railway passengers to the Royal Crematorium during the death and funeral of King Bhumibol Adulyadej.
Ban Phachi Junction is a railway junction located in Phachi District, Ayutthaya Province, Thailand. It is a Class 1 Station and serves as a junction for the North and Northeastern Line of the State Railway of Thailand. Ban Phachi Junction had to be rebuilt after the Second World War after being hit by Allied Bombing. Some special express and express trains do not call at this station.
Lopburi railway station is a class 1 railway station in the centre of Lopburi, Thailand, located 133 km (83 mi) away from Bangkok Station. It is a terminus for commuter train services on the Northern Line. Two large golden monkey sculptures are located on the platforms as the monkey is the symbol of Lopburi. The opposite side of the station building is an important archaeological site of Lopburi, Wat Phra Sri Rattana Mahathat.
The Northern Line is a railway line in Thailand, running between the capital Bangkok and the northern city of Chiang Mai. It is the second longest railway line in Thailand at 751 kilometres (467 mi) long, has 130 operational stations and halts, and is operated by the State Railway of Thailand. The line first opened in 1896. Major cities served by the line include Bangkok, Ayutthaya, Nakhon Sawan, Phitsanulok, Lampang, and Chiang Mai.
The PNR 900 class is a class of 21 GE Universal Series diesel–electric locomotives operated by the Philippine National Railways since 1973. The locomotives comes with three different types: U14CP (1973), U14C (1979), and U15C (1991). Initially used for long-distance express services throughout Luzon, they were relegated to hauling commuter trains within Metro Manila, a task previously done by PNR's diesel multiple units fleet. This was further exacerbated by the closure of the PNR South Main Line's intercity section in 2012 after an accident in Sariaya, Quezon.
Sala Thammasop railway station is a railway station located in Sala Thammasop Subdistrict, Thawi Watthana District, Bangkok. It is a class 3 railway station located 14.05 km (8.7 mi) from Thon Buri railway station.
The history rail transport in Thailand began with the opening of the Paknam Railway on 11 April 1893.
The Manila Railroad 170 class were ten 4-8-2 Mountain steam locomotives operated by the Manila Railroad Company (MRR), predecessor of the Philippine National Railways. They were built alongside the 2-10-2 Santa Fe-type Manila Railroad 200 class by the American Locomotive Company at its Brooks facility between 1921 and 1922. During its service at the MRR, it carried passenger trains on the South Main Line between Manila and the Bicol Region.
The Manila Railway 70 class of 1908 was a class of at least twenty-two 0-6-2 side and well-tank locomotives built by the North British Locomotive Company. These locomotives were first put into service on a mainline during the late 1900s and early 1910s by the Manila Railway Company. Their primary purpose was to support the growing network and replace the aging Dagupan class engines. They were used on all the lines of the Manila Railway and its succeeding incarnation, the Manila Railroad. Over time, some locomotives were either scrapped or given to sugarcane plantations after being withdrawn. The last unit, No. 79, remained in service with the Pampanga Sugar Development Company as late as 1989.
The Manila Railroad Company (MRR) was a Filipino state-owned enterprise responsible for the management and operation of rail transport in the island of Luzon. It was originally established by an Englishman named Edmund Sykes as the private Manila Railway Co., Ltd. on June 1, 1887. British engineer Horace L. Higgins was then assigned as its first general manager in Manila. On July 7, 1906, a separate private entity named the Manila Railroad Company of New Jersey was established. The two companies continued to own the Luzon railroad network until February 4, 1916 when the Insular Government acquired both companies and absorbed them into the new Manila Railroad.
The PNR 5000 class are diesel-electric locomotives acquired in 1992 by the Philippine National Railways.
