During WW1 a number of railwaymen volunteered (or were conscripted) into the armed forces. Some positions , such as drivers, firemen and guards were Reserved - they could not leave to join up. Many other grades, such as clerical were able to leave, and it was to allow these men to leave that many women were taken on for the duration of the war. Whether as clerical workers, ticket staff, cleaners and porters, or as signaller these women proved they were capable of the work and led ultimately to the Vote and greater enpowerment.
Inevitably a number of the men who joined the Army or the Navy paid with their lives.
The Company commissioned a War Memorial for the Glasgow Terminus at St Enoch, listing the many employees who were killed.
