The first stage in gettingout work is to lay it off from the wooden templates.Each hole is marked with a punch, the number of the jobpainted on the plate bar, or shape, and other facts ofimportance are indicated. The members then go to theshears, which are located at the north end of the building,and are cut to the required form and size. They are thenmoved southward to the punches, after which they areassembled and riveted together. After they are punchedthey are carried on tracks elevated about two feet and ahalf above the floor, or at a convenient height for theworkmen. The lower chords of the roof trusses are formed of built-up I beams, which carry transverse trolleys for movingheavy parts. Longitudinal tracks are also supported fromthe roof and carry trolleys, so that any part of the floorcan be reached by the two systems. The south end ofthe shop is provided with SRiaU traveling cranes carried 64 THE RAILROAD AND (February, 1892. Text Appearing After Image: Vol. LXVl, No. .-.) ENGINEERING JOURNAL. 65 on longitudinalbeams. These in turn are carried onwheels which run on the lower chords of the roof trusses.The longitudfnal beams are made in separate sections, sothat they can be moved transversely on the roof chords.In this way the cranes command the whole floor area ofthis part of the shop. The material enters the shop atthe north end and is kept moving southward between allthe stages of completion, and is carried out at the southend when finished to a yard outside of the shop providedwith cranes for handling heavy work and placing it oncars for shipment. A very commendable feature in this shop is the greatamount of light which is provided. The loof trusses aresupported by built-up wrought-iron columns, and all thespace between them, excepting that about eight feet fromthe floor, is enclosed by window sashes. The space be-low the windows in winter is enclosed by removable wood-en sections which are put up in winter and taken down insummer
