The New Zealand Railways Magazine, Volume 10, Issue 12 (March 2, 1936)
Ten years ago the N.Z. Railways Department set up a Suggestions and Inventions Committee, which invited members of the staff and the general public to offer notions for improvement of equipment, service, and so on. Up to a recent date the total of suggestions had reached 9,897, of which 914 were recommended for adoption. Awards and commendations were granted in 546 cases.
New Zealand's example was followed five years ago by the Canadian National Railways. In this period the tally of suggestions for the improvement of tools, equipment and working and housing conditions exceeded 10,000, of which more than 5,000 were adopted. More than 8,000 of the suggestions came from representatives of the employees.
