This switch is typically used for number seven through number ten turnouts. The layout here is shown for a left-hand turnout, but the components are the same for either a left or right-hand con˜guration. Switches like this one can be supplied with either rigid or adjustable braces. The adjustable braces are more expensive, but are preferred in heavier duty applications. The illustration above shows both rigid and adjustable brace options. The rigid brace plating pattern is shown on the rail at the top of the page and the adjustable brace pattern is shown on the rail below. The actual layout would follow one pattern or the other; either all rigid or all adjustable braces. Listed on the opposite page is a typical bill of materials for a 16 feet 6 inches switch with adjustable braces. The gage plates and switch rods can be supplied with insulation if necessary. The bill of materials is frequently changed to accommodate speci˜c customer preferences. Common changes include: substituting rigid for adjustable braces, adding the No. 0 plates, and using ˚at twin or fewer hook twin tie plates.16 feet 6 inches STRAIGHT SPLIT SWITCH WITHGRADUATED RISERS L LR 23 23 L LR 23 23 L LR 23 23 L LR 27 27 L LR 27 27 L LR 27 27 L LR 27 27 L LR31 31 L LR31 31 L LR31 31 L LR 31 31 L LR 27 27 L LR 27 27 L LR 27 27 L LR 27 27 L LR 23 23 L LR 23 23 L LR 23 23 Shoulder BoltsSpread at Heel = 6-1/4 inches Angle of Switch, 1°-46 feet -22 inches 20 inches Standard Tie Plates 10 inches 10 inches 20 inches 2 feet -3 inches Typical bill of materials: 1 pair 16 feet 6 inches Single Reinforced Switch Points with transit clips 1 each Non-Insulated Head Rod 1 each Non-Insulated Tie Rod 1 each Non-Insulated Gage Plate (No. 1 G) with adjustable braces 8 each Brace Plates with adjustable braces (2 ea.
