Ballast Experiments. Figure 1 depicts the track layout and ballast experiment test sections. When FAST operations began in September 1976, the ballast tests included ballast shoulder width (Section 15), ballast depth (Sections 18 and 20), and ballast type (Sections 18 and 20). These tests were concluded at 425 MGT.
