Biography

Aspinall was born on 25 August 1851 in Liverpool to a Roman Catholic judge.[1][2] He attended the Roman Catholic boarding school of Beaumont College, Berkshire before being apprenticed to engineers John Ramsbottom and Francis Webb of the London and North Western Railway in 1868.[1][2] He was sent by Webb to the United States of America in 1872 where he was greatly impressed by the larger loading gauge in use there.[1]

In 1875, he moved to the Great Southern and Western Railway of Ireland and became their works manager at Inchicore, Dublin.[2] Aspinall was promoted to Locomotive Superintendent in 1883[3] and introduced a form of vacuum braking to his locomotives which was soon adopted by several other lines, including the London and North Western and Great Northern Railways.[1] He was succeeded at Inchicore by Henry Ivatt and was to keep links with both Inchicore and Ivatt.[1][4]

He became the Chief Mechanical Engineer of the Lancashire and Yorkshire Railway in 1886. Continuing the work of his predecessor, William Barton Wright, he modernised the locomotive stock and continued Barton Wright's philosophy of standardisation, bringing in several of his own design.[1][4]

He was promoted to L&YR general manager in 1899,[2] a position he was to hold until 1919.[4] In this capacity he introduced electrification and greatly expanded the transport of coal.[1]

Aspinall served as president of the Institution of Mechanical Engineers between 1909 and 1910 and was interned in Germany at the outbreak of the First World War in 1914.[1] Aspinall received a knighthood on 13 June 1917 for his contributions to the war effort and national transport system.[2][5] He served as president of the Institution of Civil Engineers between November 1918 and November 1919.[6] He was the first recipient of the Institution of Mechanical Engineers' James Watt International Medal, receiving it in 1937.[7] He died on 19 January 1937.[1] His son, John, was a first-class cricketer.[8]

He wrote seven academic papers and was the holder of fourteen patents.[1]
