Derby Locomotive Drawings List.Xlsx
Derby Locomotive Drawing Lists Description: The collection consists of approximately 6000 drawings, plus 135 registers and lists. They cover the period from 1874 to 1961. The drawings relate to the construction, modification and rebuilding of locomotives of the Midland Railway, London Midland & Scottish Railway and British Railways, with occasional drawings from other railway companies and contractors. The drawings are mainly on linen with some blueprints, as well as Ozalid and paper copies. Each drawing has a number and/ or a letter code. These letter and number codes also relate to the registers, schedules and lists. The significance of these codes is explained in the ‘System of Arrangement’ section below. System of Arrangement: The drawings are arranged in the archive in five series and are listed as such in the catalogue. 1. Main Series. These are organised by drawing number in numerical sequence. Most drawings have a two number date prefix that usually relates to the year in which the drawing was produced, but may sometimes relate to the year the drawing was entered in the register. 2. D Numerical series. These are also organised by drawing number, but prefixed by the section reference, such as D1, D2, D3, D4 or D5. 3. Diagrams and Sketches. These are also organised by drawing number, but prefixed according to the section reference code, such as DS, DD, S, D or ED. 4. BR Standard Drawings from Derby. These drawings are proper to the main collection of British Rail Standard Drawings, but were found with the main Derby Works sequences. They are numerical with the prefix SL/DE.
