Charles Reboul Sacré (4 September 1831 – 3 August 1889) was an English engineer, Engineer and Superintendent of the Locomotive and Stores Department of the Manchester, Sheffield and Lincolnshire Railway. Samuel Waite Johnson was his assistant between 1859 and 1864. Sacre retired in 1886 and committed suicide by shooting himself, reputedly due to the Penistone rail crash of 1884.
Charles Sacre was one of thirteen children born to John Joseph Berlot de Sacre. The family was of Huguenot origin. He was articled to Archibald Sturrock at the Great Northern Railway works at Boston, Lincolnshire in 1846, and upon the completion of the apprenticeship, he was appointed Assistant Locomotive Superintendent at Peterborough. (This was an out-station of the new central workshop at Doncaster, which opened in 1853.)
In 1858, he was appointed Chief Engineer and Locomotive Engineer of the Manchester, Sheffield and Lincolnshire Railway, commencing work at their Gorton works on 1 April 1859. His employees found him a friendly and approachable man, and he became popular with the work force. He was responsible for an outstanding series of double framed 0-6-0 goods engines, the largest of which were a class of sixty built in 1880-5. For the fast expresses that were being introduced on the Cheshire Lines Railway, he designed a massive outside cylinder 2-2-2 with 7 ft. 6ins. (2.286 metre) driving wheels. Another successful design was an inside cylinder 4-4-0 with double frames. Several of the 0-6-0 and 4-4-0 locomotives lasted in service until the 1920s. In the realm of civil engineering, he suggested extending the then main line by a tunnel under the Humber to Hull, but this brought him into conflict with Edward Watkin, the Company Chairman.
