Show LAYING RAILS AT NIGHT. Railroad construction at night is made possible, says a scientific journal, jour-nal, by tho uso of a freight car as a lighting plant Projecting from a tower built at one end of the car is a light arm that extends far out over tho track. At tho extreme end of this arm two search lights aro placed, while other lamps aro located at intervals in-tervals along: the arm. By means of this arrangement plenty of light can bo shed upon the portion of the track that tho arm overhangs, while beams of tho searchlights can be cast ahead where the work of preparing tho roadbed road-bed is under way. The lighting plant .permits of carrying on work in tho cool hours while tho torrid sun is below-tho horizon. oo |
