The BB302 is a class of diesel-hydraulic locomotives built by Henschel in West Germany for the Indonesian State Railway (PNKA) and entered service in 1970. All units of BB302 class were allocated to North Sumatra.
The BB302 class has a length of 11,200 mm (12 yd 0 ft 9 in ), width of 2,800 mm (3 yd 0 ft 2 in ), and height of 3,690 mm (4 yd 0 ft 1 in ). It weighs 44 tonnes (43 long tons ; 49 short tons ). Its maximum speed is 80 km/h (22 m/s). The class were originally powered by a Maybach Mercedes-Benz 12V 493 TZ10B diesel engine with 900 hp (670 kW). In 1998–2000, midlife overhaul program was carried out on all units to increase the power to 1,000 hp (750 kW) by replacing the original engine with an MTU engine. It rolls on a B′B′ axle, with two bogies, each of which has two drive shafts connected to each other. It is usually used to pull passenger trains or freight trains, including for shunting. [1]
The BB302 class is part of the Henschel DHG1000BB series, which also includes the BB303 class. This locomotive class were visually indistinguishable with the later BB303 class, with the major difference being the weight, as the BB302 are slightly heavier than BB303. Other difference are the control stand for BB302 is located on the right-hand side of the cab. Early in its service, the BB302 also used spoked wheels, which were later replaced by the more common solid wheels. [1]
The BB302 class is a unique locomotive because it is endemic to North Sumatra, the only place it operates, with only 6 units. The BB302 class entered service in 1970. It was introduced there to augment the BB300 class as part of locomotive modernization program to replace the steam locomotives. [1]
Over the years, the BB302, together with its siblings namely the Henschel-built BB303 and BB306 classes dominated the railways in North Sumatra as a universal locomotive for hauling passenger and freight trains. Initially, the BB302 locomotive used the Maybach Mercedes Benz type MB 12V 493 TZ10B engine. [1]
After 25 years of operation, this locomotive class was rehabilitated by changing its engine to an MTU diesel engine. [2] The rehabilitation was carried out in 1998–2000 (along with the BB303 in North Sumatra).
With the arrival of BB203 and CC201 in North Sumatra, the role of the BB302 locomotive shifted. BB302 were assigned for short to medium distance trains, and later only used as shunters. [3] As of 2021, only 1 out of 6 BB302 units are serviceable. [4]
The BB302 70 01 is the only remaining BB302 locomotive at the Medan depot which has the PJKA's distinctive yellow-green livery. The BB302 70 06 was declared unfit for hauling duties, and later used only as a shunter at Pulu Brayan workshop, also using vintage livery. The rest of the class were declared unfit for service. [3]
The British Rail Class 08 is a class of diesel-electric shunting locomotives built by British Railways (BR). As the standard BR general-purpose diesel shunter, the class became a familiar sight at major stations and freight yards. Since their introduction in 1952, however, the nature of rail traffic in Britain has changed considerably. Freight trains are now mostly fixed rakes of wagons, and passenger trains are mostly multiple units or have Driving Van Trailers, neither requiring the attention of a shunting locomotive. Consequently, a large proportion of the class has been withdrawn from mainline use and stored, scrapped, exported or sold to industrial or heritage railways.
Under the Whyte notation for the classification of steam locomotives, 0-6-2 represents the wheel arrangement of no leading wheels, six powered and coupled driving wheels on three axles and two trailing wheels on one axle.
Under the Whyte notation for the classification of steam locomotives by wheel arrangement, 2-6-6-0 is a locomotive with one pair of unpowered leading wheels, followed by two sets of three pairs of powered driving wheels and no trailing wheels. The wheel arrangement was principally used on Mallet-type articulated locomotives. Some tank locomotive examples were also built, for which various suffixes to indicate the type of tank would be added to the wheel arrangement, for example 2-6-6-0T for an engine with side-tanks.
The British Rail Class 97/6 0-6-0 diesel shunting locomotives were purpose-built for departmental duties by Ruston & Hornsby at Lincoln in 1953 (97650) or 1959 (97651-654). There are minor technical differences between 97650 and the 1959 batch.
The majority of Indonesia's railways are on Java, used for both passenger and freight transport. There are three noncontinuous railway networks in Sumatra while two new networks are being developed in Kalimantan and Sulawesi. Indonesia has finalized its plan for a national railway network recently. According to the plan, 3,200 km of train tracks that will criss-cross the islands of Sumatra, Java, Kalimantan, and Sulawesi, it has been touted as the most extensive railway project in Indonesia since its independence from the Dutch in 1945. Indonesia targets to extend the national railway network to 10,524 kilometres by 2030. As of September 2022, the network spans 7,032 km.
PT Kereta Api Indonesia (Persero) (lit. 'Indonesian Railways (State-owned) Limited', abbreviated as PT KAI or simply KAI) is a major railway operator in Indonesia and one of the public railway companies in the country. It is state-owned and pays track access charges. Its headquarters are located in Bandung, West Java. In 2019, KAI carried 429 million passengers and 47.2 million tonnes of cargo.
The DF4 is a type of diesel-electric locomotive used in the People's Republic of China. It has been in production since 1969 and is still produced as of 2007 by several local companies. It is the most common locomotive in China and is used for both passenger and freight services.
T44 is a Swedish diesel-electric locomotive built by Nydqvist & Holm (NOHAB) and Kalmar Verkstad (KVAB) in 123 units between 1968 and 1987. It was the successor of T43, and used both for hauling and shunting. It is the most common diesel locomotive in Sweden, with state-owned Green Cargo as the largest operator. Other operators include Israel Railways (one), Malmtrafik (two) and formerly Norwegian State Railways and Inlandsbanan AB.
The Class V 160 is a class of diesel-hydraulic locomotives of the German railways. It is the first variant of the V160 family, built for the Deutsche Bundesbahn for medium/heavy trains.
The Ambarawa Railway Museum is a museum located in Ambarawa in Central Java, Indonesia. The museum preserves around 21 steam locomotives and focuses on tourism train tours hauled by 3 operational steam engines and a hydraulic diesel engine, using the remains of the closing of the 3 ft 6 in (1,067 mm) railway line.
The GE U20C diesel-electric locomotive was introduced by GE Transportation Systems as an export model in 1964. It was powered by the 8-cylinder 7FDL-8 engine. This locomotive is used worldwide with many variations and modifications. Different engines may be used, e.g. 7FDL8 and 7FDL12. Like the other members of the Universal series, it can be built to suit all track gauges.
Medan Station (MDN) is the main railway station in Medan, North Sumatra, Indonesia. In addition to intercity services operated by Indonesia's national rail operator, Kereta Api Indonesia, the station also has service to Kualanamu International Airport via Kualanamu ARS.
The Tasikmalaya derailment occurred on 4 April 2014 at 18:30 local time when the passenger train "Malabar", with 250 passengers on board, was derailed by a landslide in Kadipaten, Tasikmalaya Regency, West Java. The accident killed 5 people and another 35 were injured. Heavy rain triggered the landslide, which derailed the train as it traveled through Java, the most populous island in Indonesia.
The GE CM20EMP diesel-electric locomotives are owned by Kereta Api Indonesia and built by GE Transportation. The GE CM20EMPs are multipurpose locomotives, not only for hauling passenger trains, but also freight trains.
Kualanamu International Airport Station (KNM) is an airport railway station located in Kualanamu International Airport complex, in Beringin, Beringin, Deli Serdang Regency, North Sumatra, Indonesia.
