Tanner Master Carpenter, Baltimore Division In Railway Agre Gazette IN renewing the stringers in the trestle ap-proach to the Baltimore & Ohio coal pier atCurtis Bay, Md., it was essential that thework be handled without delay to the trainsof coal which pass over this trestle to the pier. SKETCH SHOWING METHOD OF PULLING IN NEW TRESTLE STRINGERS WITHOUT WEAKENING THE STRUCTURE every ten or fifteen minutes, day and night. Anyinterference to these trains would have meantconsiderable delay in the yard operation andto the traffic on the road, as well as inconve-nience in the loading of ocean liners.
