[2] Atock was born in June 1834 in Preston, Lancashire to George and Hephzibah Attock.
His baptism took place in the parish church of Preston Minster on 26 June 1834 where the Reverend Roger Carus Wilson recorded his name as Martin Atock using the common spelling of the surname for the locality rather than that of his father.
[6] His final post was of Locomotive Superintendent of the Midland Great Western Railway at Broadstone works from 1872.
They were problematic running in reverse and new locomotives and rebuilds after his departure quickly changed to a conventional square cab design.
He was aided by the expansion of Broadstone works in 1878 making it more suitable for the construction of locomotives.
