The alignment chart for MP 205-206 (from the Bridge to Main Street in Burlington) list three ballast types over the years, chatts 1943, L. S. 1957, and slag 1960. I assume L. S. is limestone, and I know what slag ballast looks like, but what is chatts, and what does it look like? I ask Steve Holding, and he thinks it’s unscreened crushed limestone, but if that’s true, why would the alignment chart list chatts in 1943 and L.S. in 1957 if they’re the same thing?
