“Black Out” Problem.

Many ticklish problems have been presented by the “black-out” in connection with marshalling-yard operation, but by degrees these have been solved, and it is remarkable how marshallingyard staffs and trainmen are adapting themselves to the necessary lighting restrictions. Passenger stations, of course, have to be watched as regards the obscuring of lights, and roof glass has been specially treated. Locomotive precautions include the use of blue headlamps, and the fitting of anti-glare curtains to engine cabs. Colour light signals and station hand-lamps are controlled by the employment of long shades over the lenses. A.R.P. activities of the railways also include the provision of secure shelters at the principal stations for the use of passengers and staff, while as a measure of precaution many headquarters and divisional offices have been moved to safe sites in the country, merely skeleton staffs being maintained in the city offices.
