Boulton's Siding
Boulton's Siding was a British locomotive-hire business owned by Isaac Watt Boulton and situated alongside the Oldham branch of the Manchester, Sheffield and Lincolnshire Railway at Ashton-under-Lyne. It operated from 1864 to 1898. Overview. In the 1860s, established railway companies were replacing their small 2-2-0 and 0-4-0 steam locomotives with larger, more modern machines. Mr I. W. Boulton took advantage of this by buying up some of the old locomotives, modifying them in his workshop, and hiring them out to contractors for use on civil engineering projects, including the  building of new railways. The usual modifications were to fit smaller driving wheels (to increase tractive effort) and to convert tender locomotives to tank locomotives. By the 1880s, the hire business was declining so Mr Boulton started building new locomotives. He used his own patent design of boiler which had a single large flue with cross water-tubes. This was, essentially, a horizontal predecessor of the vertical water-tube boilers later used in Sentinel Steam Waggons. Although Boulton's boilers steamed well, they were difficult to repair so they never became popular. The business declined during the 1890s and closed  in 1898. Mr Boulton died in 1899. Sources. This book was founded on a series of articles contributed by the author to the Locomotive Magazine between November, 1920, and February, 1925. During publication many new facts came to light. These [were] incorporated and the whole was carefully revised and re-arranged.
