He was born on 26 May 1868 at
Raheny, County Dublin, in Ireland, the seventh son of John Maunsell, a Justice of the Peace and a prominent solicitor in Dublin. He attended
The Royal School, Armagh from 1882 to 1886. He commenced studies at
Trinity College, Dublin on 23 October 1886 for a law degree; however by this stage he had shown a keen interest in engineering. He concurrently began an apprenticeship at the
Inchicore works of the
Great Southern and Western Railway (GS&WR) under
H. A. Ivatt in 1888. Following completion of his degree in January 1891 he was able to complete his apprenticeship at
Horwich Works on the
Lancashire and Yorkshire Railway (as
Nigel Gresley had done before him). At Horwich, he worked in the drawing office, before occupying the post of locomotive foreman in charge of the
Blackpool and
Fleetwood District. It was at a social evening organised by the L&YR's
Aspinall that Maunsell was to meet his future wife, Edith Pearson. He evidently impressed Edith as she was to send him a letter in March 1893 requesting a tour of the grain elevator at
Fleetwood Docks. Their correspondence became increasingly familiar and on 1 August 1893 Maunsell wrote to Edith's father requesting permission for an engagement to be married, which was refused on the basis of funding with Edith sent to Paris. Maunsell went to
India in 1894, as assistant locomotive superintendent of the
East India Railway, He subsequently was appointed district locomotive superintendent of the
Asansol District. He returned in 1896 to become works manager at
Inchicore on the GS&WR.,
Robert Coey having been promoted to locomotive superintendent on the departure of
Henry Ivatt.
O.S. Nock comments "with Robert Coey as Locomotive Superintendent and R. E. L. Maunsell as Works Manager at Inchichore the whole department was run with a smoothness to equal anything in the British Isles". The increased salary with a free house finally met the income stipulations of Edith's father and enabled Maunsell to marry Edith on 15 June 1896 in London. Maunsell moved up to become locomotive superintendent in 1911. In 1913, he was selected to succeed
Harry Wainwright as CME of the
South Eastern and Chatham Railway (SE&CR). When that line was merged in the
1923 grouping, with
Urie of the
London and South Western Railway retiring and with
Billinton of the
London, Brighton and South Coast Railway having less experience, he became chief mechanical engineer of the newly formed Southern Railway. He retired in 1937,
Oliver Bulleid taking over from him. He was appointed a Commander of the
Order of the British Empire in the
1918 New Year Honours for his efforts during the First World War. He died in
Ashford, Kent on 7 March 1944. ==Locomotives==
