The Siemens Asiarunner locomotives are contemporaries to the Eurorunner class and are designed specifically for the South-East Asian market - in particular metre gauge - key features are a Co'Co' wheel arrangement (resulting in low axle loads) and good clearance (see Loading gauge)
Much of the development of the Asiarunner locomotive had to be done from scratch, since Siemens had no contemporary example of a narrow gauge, or of a locomotive that was built to a smaller loading gauge that UIC 505-1. [4]
Nevertheless, the design mirrors in part the modular concept found in Siemens other locomotives (the Eurosprinter and Eurorunner). The main frame is one such module. The drivers cabins are also modular components.
Access to the main engine compartment is via the roof, which has three removable segments, there is a single side corridor which allows an escape route in the event of certain emergencies [5] (compare the wide gauge Eurorunners which have two passageways)
The engine is a 12-cylinder MTU model - similar to that used in the Eurorunner except with 12 instead of 16 cylinders.
The locos can work in multiple with up to three connected.
Whilst the Asiarunner was designed for use in Asia, Africa, South America and Australia, its only operator is Vietnam Railways, with 16 AR15s running passenger and freight services on its Hanoi – Da Nang – Ho Chi Minh City route. [3]
A narrow-gauge railway is a railway with a track gauge narrower than standard 1,435 mm. Most narrow-gauge railways are between 600 mm and 1,067 mm.
The Mallet locomotive is a type of articulated steam railway locomotive, invented by the Swiss engineer Anatole Mallet (1837–1919).
A Fairlie is a type of articulated steam locomotive that has the driving wheels on bogies. The locomotive may be double-ended or single ended. Fairlies are most famously associated with the Ffestiniog Railway in North Wales.
Under the Whyte notation for the classification of steam locomotives, 0-6-0 represents the wheel arrangement of no leading wheels, six powered and coupled driving wheels on three axles and no trailing wheels. This was the most common wheel arrangement used on both tender and tank locomotives in versions with both inside and outside cylinders.
Under the Whyte notation for the classification of steam locomotives, 2-8-0 represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, eight powered and coupled driving wheels on four axles, and no trailing wheels. In the United States and elsewhere, this wheel arrangement is commonly known as a Consolidation, after the Lehigh and Mahanoy Railroad’s Consolidation, the name of the first 2-8-0.
The Indian Railways primarily operates fleet of electric and diesel locomotives, along with several compressed natural gas (CNG) locomotives. Steam locomotives are operated on a few World Heritage Sites and also run occasionally as heritage trains. A locomotive is also known as a loco or more popularly as an engine. The country's first steam locomotive ran on the Red Hill Railway from Red Hills to the Chintadripet bridge in Madras in 1837.
The N class was a branch line steam locomotive that ran on Victorian Railways from 1925 to 1966. A development of the successful K class 2-8-0, it was the first VR locomotive class designed for possible conversion from 5 ft 3 in to 4 ft 8+1⁄2 instandard gauge.
The Victorian Railways H class was an express passenger steam locomotive operated by the Victorian Railways from 1941 to 1958. Intended to eliminate the use of double heading A2 class locomotives on The Overland services on the steeply graded Western line to Adelaide, wartime restrictions led to only one locomotive being built. Nicknamed Heavy Harry, H220 was the largest locomotive ever built in Australia and the largest non-articulated steam locomotive to run on Australian railways.
The Victorian Railways J class was a branch line steam locomotive operated by the Victorian Railways (VR) between 1954 and 1972. A development of the successful Victorian Railways K class 2-8-0, it was the last new class of steam locomotive introduced on the VR. Introduced almost concurrently with the diesel-electric locomotives that ultimately superseded them, the locomotives were only in service for a relatively short time.
The EuroSprinter family of electric locomotives is a modular concept of locomotives for the European market built by Siemens Mobility. The internal Siemens product name is ES 64, with ES for EuroSprinter and the number 64 indicating the 6,400 kW power at rail.
Siemens Mobility is a division of Siemens. With its global headquarters in Munich, Siemens Mobility has four core business units: Mobility Management, dedicated to rail technology and intelligent traffic systems, Railway Electrification, Rolling Stock, and Customer Services.
The Einheitsdampflokomotiven, sometimes shortened to Einheitslokomotiven or Einheitsloks, were the standardized steam locomotives built in Germany after 1925 under the direction of the Deutsche Reichsbahn-Gesellschaft. Their manufacture made extensive use of standard design features and components.
The Stadler Euro is a class of diesel-electric locomotives built by Stadler Rail for the European market. It is available in two basic variants, the four-axle Euro 3000, and the six-axle Euro 4000. These locomotives are powered by EMD 710 prime movers. A six-axle electric-only variant is marketed as Euro 6000; it is also built for the Iberian gauge.
The Eurorunner family of locomotives are a series of medium- to high-power diesel-electric locomotives built by Siemens for the European market. Introduced from 2002 onwards, they share design characteristics with the successful Eurosprinter range of electric locomotives, also built by Siemens.
The GE Universal Series is a series of diesel locomotives intended for the export market introduced by General Electric in early 1956. General Electric had previously partnered with Alco, producing locomotives for export using Alco’s 244 engine, and provided electrical parts for Alco’s domestic production. However, with the advent of the Universal Series, GE ended its partnership with Alco and entered the export locomotive market on its own.
The Vectron is a locomotive series made by Siemens Mobility, introduced at the 2010 InnoTrans trade fair in four prototype versions: diesel, multi-system, and both AC and DC electric power. The diesel version has been replaced in 2018 by a dual mode locomotive which is powered by electricity on electrified sections of the track and can be switched to diesel mode on non-electrified sections. The Vectron series is reconfigurable and modular, with a Bo'Bo' wheel arrangement, and is intended as the successor to the EuroSprinter family of locomotives. A more affordable, basic version called Smartron was introduced in 2018.
The South African Railways Class NG G11 2-6-0+0-6-2 of 1919 was a narrow gauge steam locomotive.
The South African Railways Class GA 2-6-0+0-6-2 of 1921 was an articulated steam locomotive.
The Stadler Eurolight is the brand name for a family of 4-axle Bo'Bo' mainline diesel-electric locomotives with sub-20-tonne axleloads for passenger and freight trains produced by Stadler Rail.
The GE PowerHaul is a class of mainline diesel-electric locomotives designed by General Electric. Thirty locomotives were ordered by Freightliner in 2007; the first locomotive was completed in July 2009 at GE's Erie, Pennsylvania, plant.
AsiaRunner AR15 VR is the first locomotives in the Asian Runner family for the small gauges: 1000 and 1067mm
