FS Class D.445 : ウィキペディア英語版 | FS Class D.445
The Class D.445 is a class of diesel locomotives used by the italian Ferrovie dello Stato (FS) railway company and by Trenord. 150 units were built between 1974 and 1988, divided into three series. ==History== The D.445 represented an evolution of the FS Class D.443 engine, maintaining the predecessor's reliability and operational capabilities. At the beginning of the 1970s FS, during a plan aimed at the expansion and modernization of current service, designed a new version of an unified diesel engine which could also resolve the issue of supplying power to heat carriages in an efficient way through a high voltage Head end power supply (REC) fed by a secondary generator. Previous diesel locomotives were not provided with this and so required the use of a generator wagon (Carro Riscaldo), leading to increased weight. The first series of locomotives, introduced from 1974, were built with curved front windscreens which would be later replaced by cheaper and sturdier flat ones. In 1979 a second series was ordered, fitted with equipment for use with control cars. At the end of the 1980s the whole group consisted of 150 units which allowed the retirement of the then old D.341 and D.342 locomotives.
