Canadian Railwayman Honored.— C. Ramsay, chief engineer for construction. Eastern lines,C. P. R., and now with the Canadian Army in France, hasbeen made a Companion of the Order of St. Michael and THE fact that the distance from the cab deck to the bot-tom of the firedoor varies on our modern locomotivesfrom 17 2 in. to 26 in. shows that no very great con-sideration has been given to this particular feature of locomo-tive design. It has, however, an important bearing on efficientlocomotive construction, for with an improperly located fire-door the fireman cannot perform his work efficiently. In orderto determine as near as possible the proper height at which thefiredoor should be located, the Pennsylvania Railroad con-ducted some unique tests at its Altoona test plant which givewithout question the most authoritative information on thissubject. These tests show that regardless of the height of a fire-man, freer action of the arms and body will be obtained withthe bottom of the firedoor located 22 in. above the cab deckand that the coal should always be within reach of the fire-man. The tests were made on a firing platform which had thedimensions of the cab and tender of a class
