Class 47/7 47727 ‘Rebecca’ Colas Rail

The popular BR Class 47 Diesel Locomotive returns to the Graham Farish range with models of the ‘Crewe-Cut’ locomotives available for the first time thanks to the development of new tooling that further expands the range of Class 47s that can be modelled in N scale. Many Class 47s had the cowling around their bufferbeams removed in later life, changing the appearance of the lower front end and with this work usually being undertaken at Crewe Works, the resultant locomotives were commonly termed ‘Crewe-Cut’ machines. No. 47727 is one such machine, originally built as D1629, in 1981 it was fitted with Electric Train Heating (ETH) and became 47569 and later still was renumbered to 47727 in 1994 following the fitting of extended range fuel tanks. Whilst in Colas Rail ownership, in 2007 the locomotive was named ‘Rebecca’; today this Class 47 is operated by GBRf and has subsequently been re-named as ‘Edinburgh Castle/Caisteal Dhun Eideann’.

Further developments to the Graham Farish Class 47 come in the form of technical advancements, with an upgraded specification which now boasts a Next18 DCC decoder interface, pre-fitted speaker, cab lighting (when used on DCC) and independent control of the directional lights at each end. With the Next18 interface and pre-fitted speaker, SOUND FITTED models can now be offered for the first time.

CLASS 47 HISTORY

Towards the end of the 1950s, British Railways began planning a new fleet of diesel locomotives and after investigating several prototypes, BR decided to place an order with Brush Engineering for 20 locomotives during February 1961. The resulting design became the iconic Brush Type 4 Diesel locomotive, a practical, versatile design with a very distinctive cab. Powered with a Sulzer engine and initially rated at 2,750hp, the locomotive could achieve a top speed of 75mph with a tractive effort of 55,000lb. Building commenced in January 1962 and the first locomotive No. D1500 appeared in late September of the same year with test runs on the London Midland Region and Western Region. The design was a success and BR went on to order a total of 512 with continuous production through to early 1967, forming the largest single class of main-line diesel locomotives in the UK.

During this time and subsequent years, several variations appeared with an increase in speed and tractive effort to 95mph and 62,000lb respectively. Originally fitted with four character train reporting head-codes, these changed to marker lights, with the addition of high intensity lights and roof aerials in the late 1980s. Other variations involved the fitting of different types of steam heating boiler for early BR coaching stock, later replaced with electric train heating for use with modern rolling stock. The numbering system started with four figures but changed to five with the introduction of the TOPS coding system which saw the locomotives classified as Class 47 Diesels with variations such as 47/0, 47/2, 47/3, 47/4 and 47/7. By the end of the 1990s, half of the Class 47 fleet had been withdrawn or scrapped, 33 have been converted into Class 57 locomotives and several have been preserved, including the original No. D1500, now numbered 47401.
