Figure 3 shows an elevation view of the 4-hole long-toe
angle bar (24 inches in length) used for 90 lb rail and of the 6-
hole standard joint bar (36 inches in length) used for 136 lb rail.
FEA models include all four bolts for the long-toe angle bar.
Different bolt patterns are considered for cases involving
standard joint bars (e.g. four bolts versus six bolts).
