A Rebuilt diesel locomotive as the name implies is diesel locomotive that are rebuilt or modified from an older or a scrapped diesel locomotive. Some of these locomotives were converted to become cab-less, while most become a completely new type of locomotive.
History edit
Rebuilt diesel locomotives were first created in the 1960s, when railroads and railways throughout North America, and the United Kingdom (including other parts of Europe as a result of the Cold War Era and the industrialization movements revolving around during the time) had a brief shortage of locomotives after scrapping and/or retiring all (or almost all; with the exception of the Union Pacific Railroad and the Norfolk and Western Railway) of their steam locomotives in favour brand new diesel locomotives which were guaranteed to be the "next generation" of motive power. Although such railroads and railways owned some of the earliest known types of diesels ever built and manufactured (before World War II), they were in desire need of replacement. Thus, the "rebuild movement" was formed.
One of the very first known (and largest built) types of rebuilt diesel locomotives was the Santa Fe CF7; which was a type of multi-purpose switcher or shunter rebuilt from an EMD F7 (as well as other F units) by the Atchison, Topeka and Santa Fe Railway (ATSF) which was a huge success and operated on the railroad from the early-1970s to the mid-1980s.[1][2] Another known major type of rebuilt diesel locomotive is the British Rail Class 10; which is rebuilt from a British Rail Class 08 and/or the upgraded Class 09. As well as the EMD GP15 Series; such as the GP15-1 from EMD; being the only other type of locomotive rebuilt specially from the company as opposed to having numerous companies receiving permission to rebuilt former EMD-built diesels.
Rebuilt locomotives became more popular in the 1990s and into the early 2000s with some of the first high-powered, low-emission, energy-efficient hybrid diesel locomotives; which run on clean diesel fuel and ethanol oil (or biodiesel).
There are many railroads, locomotive builders, and leasing companies which are still in the process of rebuilding diesel locomotives as of today; primarily as a result of the European Financial Crisis throughout Europe, and The Great Recession in the United States, thus the economy severely affecting the fuel economies which were (obviously) main priorities for railroads and locomotive builders.
