Built between 1962 and 1968, the Class 47 Co-Co Diesel-Electric locomotive was once the most numerous class of mainline diesel in Britain with 512 examples. Brush Traction constructed 310 locomotives in Loughborough and the remaining 202 at Crewe. The locomotives were used for passenger and freight operations beginning in 1962 in the BR Green livery, before being repainted into the BR Blue colour scheme. Later diversification saw them painted in all manner of liveries.

Strong performers, these locomotives were among some of the largest to be employed by British Rail. The first five withdrawals were all due to accident damage with the first planned decommissioning taking place in February 1986. As withdrawals began, the engines were used for parts, and therefore the Class 47 disappeared slowly.

In 2023, 30 of the class remained operational on the national network with West Coast Railways being the largest operator. Around 17 were stored, 33 were converted to Class 57 and an additional 32 were preserved.

D1683 was introduced in 1963, serving ably until receiving its TOPS number and BR blue colour scheme in 1973, becoming 47485. Wearing a variant of BR blue for much of its service life including the large logo, the locomotive was scrapped in 2000 by MRJ Phillips at Crewe.

The Class 47 model of No. D183 comes in a vivid BR green livery. Etching plates on the cab front are pre-fitted. The model is sound fitted with an 8-Pin decoder and has a pre-loaded Class 47 HM7000 sound profile. The model houses a state-of-the-art sugarcube speaker. As a Railroad Plus model, it has an enhanced livery with intricate detail.
