GE ended railcar operations in Canada inBombardier Transportation continues to operate the railcar operations in Thunder Bay. Inthe grouping Bombardier Eurorail was formed consisting of the companys European subsidiaries, BN, ANF-Industrie, Prorail, inthe company acquired Mexicos largest railway rolling-stock manufacturer, Concarril, from the Mexican government.
InBombardier Transportation acquired Adtranz from DaimlerChrysler, and became by many measurements the Western worlds largest rail-equipment manufacturer, the addition of ADtranz made Bombardier a manufacturer of locomotives along with its existing product lines of passenger carriages, multiple-unit trains, and trams.
With the acquisition of ADtranz, Bombardier also gained competence in the propulsion components business. Other sites had their work reduced in scope, or were closed. In Sep the downsizing and eventual closure of the Maryborough factory was announced, in Januarythe government of Hungary nationalised the loss-making and under-utilised Bombardier carriage works at Dunakeszi, acquiring a The sale was required in part to continue the financing of the parent companys C-Series jet, in Aug Bombardier opened a 6, square metres production facility in Isando, Johannesburg, South Africa 7.
It opened in and is operated by the Heathrow Express Operating Company and it is an open access operator and not subject to franchising. Heathrow Express was planned as a joint venture between BAA and British Rail, but was taken over fully by the following the railways being privatised. The principal works were two 5-mile single-bore tunnels and underground stations at Heathrow Central and Terminal 4, electrification of the Great Western Main Line between Paddington and Airport Junction, where the new line diverged from the GWML, was also required.
A flying junction known as Stockley Flyover was constructed to connect the tunnel to the GWML fast lines, beginning in Januaryan interim service called Heathrow FastTrain ran to a temporary station called Heathrow Junction, where a coach took passengers the rest of the way.Last HST from Old Oak Common depot into London Paddington
The full service began on 23 Junewith four trains per hour running in each direction, ina service called Heathrow Connect was started, operating a twice-hourly stopping service along the route using Class Desiro EMUs.
At Paddington they use dedicated platforms 6 and 7, although on other platforms are used. There are two stops at Heathrow, Heathrow Central, serving Terminals 1,2 and 3, until the opening of Terminal 5 on 27 MarchHeathrow Express terminated at Heathrow Terminal 4, this is now served by the Heathrow Express shuttle from Heathrow Central.
Heathrow Express has been well received, not least because steps were taken to reduce the environmental impact. As of Summerall units have undergone a complete refurbishment inside and out including new seating configurations, luggage storage, Express Saver and Business First tickets are valid within 3 months of date of travel and return journey valid within 1 month of outbound journey.
Standard class travel between Heathrow stations is free, there is also a stopping service, Heathrow Connect, which takes the same route but using the slower relief lines, on which significantly lower fares are charged. This takes approximately 15 minutes longer than Heathrow Express, but offers connections to the London Underground Central, Airport workers can get a discount through the Airport Commuter scheme operated by Heathrow Airport Holdings.
Performance for the first quarter of the financial year was Diesel locomotive — A diesel locomotive is a type of railway locomotive in which the prime mover is a diesel engine. Several types of diesel locomotive have been developed, differing mainly in the means by which power is conveyed to the driving wheels.
Early internal combustion engine-powered locomotives and railmotors used gasoline as their fuel, soon after Dr. Rudolf Diesel patented his first compression ignition engine init was considered for railway propulsion. Progress was slow, however, as several problems had to be overcome, power transmission was a primary concern.
As opposed to steam and electric engines, internal combustion engines work efficiently only within a range of turning frequencies. In light vehicles, this could be overcome by a clutch, in heavy railway vehicles, mechanical transmission never worked well or wore out too soon. Experience with early gasoline powered locomotives and railcars was valuable for the development of diesel traction, one step towards diesel-electric transmission was the petrol-electric vehicle, such as the Acsev Weitzer railmotor, which could operate from batteries and electric overhead wires too.
Steady improvements in diesel design gradually reduced its size and improved its power-to-weight ratio to a point where one could be mounted in a locomotive. Once the concept of drive was accepted, the pace of development quickened. InArmstrong Whitworth of the United Kingdom delivered two 1, hp locomotives using engines of Sulzer design to Buenos Aires Great Southern Railway of Argentina, currently, almost all diesel locomotives are diesel-electric, although the diesel-hydraulic type was widely used between the s and s.
The Soviet diesel locomotive TEP lays claim to the speed record for a diesel railed vehicle. Ina 20 h. It was not, strictly, a diesel because it used a hot bulb engine, following the expiration of Dr.
Rudolf Diesels patent inhis engine design was successfully applied to marine propulsion and stationary applications. However, the massiveness and poor power-to-weight ratio of early engines made them unsuitable for propelling land-based vehicles. Therefore, the potential as a railroad prime mover was not initially recognized.
This changed as development reduced the size and weight of the engine, the worlds first diesel-powered locomotive was operated in the summer of on the Winterthur-Romanshorn Railroad in Switzerland, but was not a commercial success.

During further test runs in several problems were found, after the First World War broke out inall further trials were stopped 9. Diesel multiple unit — A diesel multiple unit or DMU is a multiple-unit train powered by on-board diesel engines.
A DMU requires no separate locomotive, as the engines are incorporated into one or more of the carriages and they may also be referred to as a railcar or railmotor, depending on country. Diesel-powered units may be classified by their transmission type, diesel-electric. The diesel engine may be located above the frame in a bay or under the floor.
Driving controls can be at both ends, on one end, or none, DMUs are usually classified by the method of transmitting motive power to their wheels. In a diesel-mechanical multiple unit the rotating energy of the engine is transmitted via a gearbox and driveshaft directly to the wheels of the train, like a car. The transmissions can be shifted manually by the driver, as in the majority of first-generation British Rail DMUs.
In a diesel-hydraulic multiple unit, a torque converter, a type of fluid coupling. Some units feature a mix of hydraulic and mechanical transmissions, usually reverting to the latter at higher operating speeds as this decreases engine RPM. In a diesel-electric multiple unit a diesel engine drives a generator or an alternator which produces electrical energy. The generated current is fed to electric traction motors on the wheels or bogies in the same way as a conventional diesel electric locomotive.
In modern DEMUs, such as the Bombardier Voyager family, each car is entirely self-contained and has its own engine, generator, a train composed of DMU cars scales well, as it allows extra passenger capacity to be added at the same time as motive power. It also permits passenger capacity to be matched to demand, and for trains to be split and it is not necessary to match the power available to the size and weight of the train, as each unit is capable of moving itself.
As units are added, the power available to move the train increases by the necessary amount, distribution of the propulsion among the cars also results in a system that is less vulnerable to single-point-of-failure outages. Many classes of DMU are capable of operating with faulty units still in the consist, because of the self-contained nature of diesel engines, there is no need to run overhead electric lines or electrified track, which can result in lower system construction costs.
Such advantages must be weighed against the noise and vibration that may be an issue with this type of train. DMUs were first introduced to Australia in the late midth century for use on branch lines that could not justify a locomotive hauled service. Electric multiple unit — An electric multiple unit or EMU is a multiple unit train consisting of self-propelled carriages, using electricity as the motive power. An EMU requires no separate locomotive, as traction motors are incorporated within one or a number of the carriages.
An EMU is usually formed of two or more semi-permanently coupled carriages, but electrically powered single-unit railcars are also classed as EMUs. EMUs are popular on commuter and suburban rail networks around the world due to their fast acceleration, being quieter than DMUs and locomotive-drawn trains, EMUs can operate later at night and more frequently without disturbing residents living near the railway lines. Each carriage had a traction motor and was specifically designed and constructed to be light in weight while running on elevated steel sections.
The first EMUs were two-carriage trains later graduating to three carriages, with the front and rear carriages powered, Liverpool Museum retains an example of the Liverpool Overhead Railway EMU carriage.

Sprague, the cars that form a complete EMU set can usually be separated by function into four types, power car, motor car, driving car, and trailer car. Each car can have more than one function, such as a car or power-driving car. A power car carries the equipment to draw power from the electrified infrastructure, such as pickup shoes for third rail systems and pantographs for overhead systems.
Motor cars carry the traction motors to move the train, and are combined with the power car to avoid high-voltage inter-car connections. Driving cars are similar to a cab car, containing a drivers cab for controlling the train, an EMU will usually have two driving cars at its outer ends. Trailer cars are any cars that carry little or no traction or power related equipment, on third rail systems the outer vehicles usually carry the pick up shoes, with the motor vehicles receiving the current via intra-unit connections.
Many modern 2-car EMU sets are set up as married pair units, while both units in a married pair are typically driving motors, the ancillary equipment are shared between the two cars in the set. Since neither car can operate without its partner, such sets are permanently coupled, advantages of married pair units include weight and cost savings over single-unit cars while allowing all cars to be powered, unlike a motor-trailer combination.
Disadvantages include a loss of flexibility, as trains must be multiples of two cars, and a failure on a single car could force removing both it and its partner from service. The retired New York—Washington Metroliner service, first operated by the Pennsylvania Railroad and later by Amtrak, also featured high-speed electric multiple-unit cars, diesel multiple unit Battery electric multiple unit British electric multiple units Media related to Electric multiple unit at Wikimedia Commons It was founded inreceived its enabling Act of Parliament on 31 AugustGoods wagons were painted red but this was later changed to mid-grey.
Great Western trains included long-distance express services such as the Flying Dutchman, the Cornish Riviera Express and it also operated many suburban and rural services, some operated by steam railmotors or autotrains.

The company pioneered the use of larger, more economic goods wagons than were usual in Britain and it operated a network of road motor routes, was a part of the Railway Air Services, and owned ships, docks and hotels.
The Great Western Railway originated from the desire of Bristol merchants to maintain their city as the port of the country. The company was founded at a meeting in Bristol in and was incorporated by Act of Parliament in Isambard Kingdom Brunel, then aged twenty-nine, was appointed engineer and this was by far Brunels largest contract to date.
It was approached via a 1: Inthe approach roads to and from the coal stage were doubled, and in an ash shelter constructed to protect from Nazi Luftwaffe bombing. The only major difference by the early s was the addition of a pre-war diesel refuelling stage just north of the repair shop, for use by GWR railcars. Some of the inspection pits in The Factory were also lengthened and deepened and jacks provided to allow for bogie and spring changing.
It opened on 20 October Just south of the residual GWR buildings, in the s BR built what was initially the storage depot for the Blue Pullman trains, what later became known as the Coronation Carriage Sidings. Today trains which operate the Great Western Railway services are maintained here.
This will cease in December In a new bespoke depot was constructed at the southern end of the site, between the Great Western depot and the main line, funded by the British Airports Authority to service and maintain the Heathrow Express and Heathrow Connect service trains.
This was the first new privately funded train depot in the UK since the British railways nationalisation in On 26 JulyFirst Great Western opened a new depot on the site of the former carriage sidings to service its Class fleet.
