The methods adopted by progressive railways for promoting safety amongst their employees are as interesting as they are varied. Safety competitions between one department and another, safety talks and discussions on the subject of accident prevention, and the extensive use of safety posters designed to feature in a graphic manner dangerous practices which should be avoided, are some of the methods employed. A variation of the safety competition method, and one which is calculated to achieve good results, is the recent provision by the New York, New Haven and Hartford Railway, of flags, on which the words “No accidents this month” are printed, the flags being raised over each shop and engine-shed on the system on the first day of each month. When an accident (as defined by the Interstate Commerce Commission) occurs in any shop or engine-shed, the flag is immediately hauled down until the first of the following month.
