Класс паровозов Great Western Railway
The Great Western Railway (GWR) 6400 Class is a class of 0 6 0 pannier tank steam locomotive introduced by Charles Collett in 1932. All 40 examples were 'auto fitted' – equipped with the remote control equipment needed for working autotrains. The 1936 GWR 7400 Class was a similar class, without the autotrain apparatus, but with a higher boiler pressure of 180 psi, providing a small but useful increase in power. An initial build of 30 in 1936 1937 was added to by British Railways in two batches each of ten locos in 1948 and 1950. These were destined for a short life, the briefest being only nine years. A minor visual difference between the 5400 and earlier 6400, and the later series of 6400, with the 7400 classes was at the join between cab and bunker. The 5400 and early 6400 had an arc whereas the later 6400 and the 7400 class was straight. The early locos also had a lip at the leading edge of the cab roof, whereas the later locos had a plain corner edge. Both classes were closely related to the 1930 GWR 5400 Class, which was in turn an evolution of both the Armstrong 1874 GWR 850 Class and the Dean 1891 GWR 2021 Class. Thus the basic design was almost sixty years old when new, the 4 feet (1 m) driving wheels being the main distinguishing factor, apart from the more modern profile. There were also superficial similarities with the GWR 645 Class as extant in the 1930s, that also had 4 feet (1 m) wheels and stroke cylinders (and by then pannier tanks and full cabs). + Table of orders and numbers Year Quantity Lot No. Locomotive numbers Notes 1932 10 277 6400–6409 1934–35 15 294 6410–6424 1935 5 300 6425–6429 1937 10 305 6430–6439 1936–37 30 307 7400–7429 1948 10 371 7430–7439 1950 10 380 7440–7449
Паровозы класса 6400 Great Western Railway (GWR) – это класс паровозов с танковым корпусом типа 0-6-0, представленный Чарльзом Коллетом в 1932 году. Все 40 машин были оборудованы системой дистанционного управления, необходимой для работы с автопоездами ("авто-оборудование"). Класс GWR 7400 1936 года выпуска был аналогичным, но без оборудования для автопоездов, зато с более высоким давлением в котле – 180 psi, что обеспечивало небольшое, но полезное увеличение мощности. Первоначальная серия из 30 локомотивов была построена в 1936–1937 годах, затем British Railways добавила два заказа по десять локомотивов в 1948 и 1950 годах. Срок службы этих локомотивов был коротким, некоторые проработали всего девять лет. Незначительное визуальное отличие между классами 5400 и ранними 6400, а также более поздними сериями 6400 и 7400 заключалось в месте соединения кабины и бункера. У 5400 и ранних 6400 эта часть имела дугообразную форму, в то время как у более поздних 6400 и 7400 – прямую. Ранние локомотивы также имели выступ на передней кромке крыши кабины, а более поздние – простой прямой угол. Оба класса тесно связаны с классом GWR 5400 1930 года, который, в свою очередь, являлся развитием классов Armstrong 1874 GWR 850 и Dean 1891 GWR 2021. Таким образом, базовая конструкция существовала почти шестьдесят лет, а основными отличительными особенностями, помимо более современного профиля, были 4-футовые (1 метр) ведущие колеса. Также наблюдалось некоторое сходство с классом GWR 645, существовавшим в 1930-х годах, который также имел 4-футовые (1 метр) колеса и цилиндры, а к тому времени – танковый корпус и полную кабину.

Меньшие колеса локомотивов серии 6400 позволяли им работать в более гористой местности, чем локомотивы серии 5400, и изначально они были направлены в долины Южного Уэльса. Локомотивы серии 6400 работали на многих бывших ветках GWR в Девоне и в окрестностях Плимута до начала 1960-х годов, когда эти ветки были закрыты или их обслуживание перешло к дизельным поездам. Локомотив № 6430 регулярно ходил по старой ветке Тависток-Саут и часто использовался с двумя моторвагонными прицепами. Локомотив № 6412 был приписан к локомотивному депо Глостер-Хортон-Роуд (85B) и 31 октября 1964 года совершил один из последних рейсов автопоезда "Chalford Railcar" между Глостером и Чалфордом. Поскольку локомотивы этого типа были приписаны к депо Плимут-Лайра, они проходили испытания на бывшей железной дороге Lostwithiel и Fowey, хотя обычно там использовались локомотивы серии 1400 Class 0-4-2.
