History

1281 Century at the Workshops Rail Museum, North Ipswich in October 2011

The 1270 class was devised by English Electric engineer Stan Lyons, based on the body design of North American road switcher but using the same engine and generator as the 1250 class. The first 12 units had the same English Electric 525 traction motors as the 1250 class. The remaining units had improved English Electric 548 traction motors with a slightly higher tractive effort. The final six units had dynamic brakes. [1]

In 1965, 1281 was named Century and painted in a commemorative gold and white livery to mark the centenary of the first railway in Queensland. [2]

They were used on grain trains between the Darling Downs and Brisbane, ore trains on the Mount Isa line and coal trains on the Moura line. [3] With higher power diesel locomotives becoming available in the 1970s, the 1270s were moved to general freight. [2]

Withdrawal & disposal

The 1270 class were displaced from coal traffic with the electrification of coalfields lines from 1986. [1] All were withdrawn between 1987 and 1989. Two units were retained by the Queensland Rail Heritage Division [2] [4] and the remainder were scrapped.

<span class="mw-page-title-main">Locomotive</span> Self-propelled railway vehicle

A locomotive 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; the use of these self-propelled vehicles is increasingly common for passenger trains, but rare for freight trains.

<span class="mw-page-title-main">Multiple unit</span> Self-propelled train

A multiple-unit train or simply multiple unit (MU) is a self-propelled train composed of one or more carriages joined, which when coupled to another multiple unit can be controlled by a single driver, with multiple-unit train control.

<span class="mw-page-title-main">Diesel locomotive</span> Locomotive powered by a diesel engine

A diesel locomotive is a type of railway locomotive in which the power source is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. The most common are diesel-electric locomotives and diesel-hydraulic.

<span class="mw-page-title-main">Electric locomotive</span> Locomotive powered by electricity

An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a battery or a supercapacitor. Locomotives with on-board fuelled prime movers, such as diesel engines or gas turbines, are classed as diesel–electric or gas turbine–electric and not as electric locomotives, because the electric generator/motor combination serves only as a power transmission system.

<span class="mw-page-title-main">Railway electrification</span> Conversion of railways to use electricity for propulsion

Railway electrification is the use of electric power for the propulsion of rail transport. Electric railways use either electric locomotives, electric multiple units or both. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines, but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches, and transformers.

<span class="mw-page-title-main">British Rail Class 08</span> Diesel-electric shunting locomotives

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.

The British Rail Class 25, also known as the Sulzer Type 2, is a class of 327 diesel locomotives built between 1961 and 1967 for British Rail. They were numbered in two series, D5151–D5299 and D7500–D7677.

<span class="mw-page-title-main">British Rail Class D16/1</span> Class of diesel electric locomotives

LMS No. 10000 and 10001 were some of the first mainline diesel locomotives built in Great Britain. They were built in association with English Electric by the London, Midland and Scottish Railway at its Derby Works, using an English Electric 1,600 hp diesel engine, generator and electrics.

A hybrid train is a locomotive, railcar or train that uses an onboard rechargeable energy storage system (RESS), placed between the power source and the traction transmission system connected to the wheels. Since most diesel locomotives are diesel-electric, they have all the components of a series hybrid transmission except the storage battery, making this a relatively simple prospect.
