Titles
Robert Chalmers (Walter's father) had held the title Assistant Locomotive Superintendent and Chief Draughtsman. Walter Chalmers succeeded his father in the same role, but the title was abbreviated to Chief Draughtsman. In 1920, he succeeded William Paton Reid who had held the role of Locomotive Superintendent, but in line with other railway companies of the era, the title of the post was changed to Chief Mechanical Engineer. His own successor in the deputy position was J P Grassick, whose job title was also changed from Chief Draughtsman to Locomotive Running Superintendent.
Locomotives
Because Grouping was imminent, Chalmers had little opportunity to develop new steam locomotive types but he did supervise the rebuilding of the last eighteen locomotives of NBR Class M 4-4-0 (later LNER Class D31). He also designed a three-cylinder 2-8-0 mineral engine but this never got beyond the drawing board.
Dimensions of LNER Class D31 (as rebuilt)
Seven D31s passed into British Railways ownership in 1948 but three of these were quickly withdrawn leaving BR numbers 62059, 62060, 62065 and 62072. The last D31 was withdrawn in 1952 and none was preserved.
Post-grouping
Chalmers continued to work for the London and North Eastern Railway after the 1923 Grouping but retired in June 1924.
