✦ Synopsis
locomotive drivers of daylight brightness in their field of vision. Experimental findings indicate that the drivers find light intensities of more than 10,000 nit disturbing and, if sustained for prolonged periods, fatiguing. The author also determined discomfort coefficients in respect of various landscapes as they appeared in the field of vision of locomotive drivers. Because of the results obtained, two thousand five hundred drivers were issued with sun-glasses for a trial period. These were found to be a positive aid and they are now to be introduced for general use by locomotive crews.
