Flat Brook, aptly named for its generally slow moving and slightly rippled flow as it meanders thru the New Haven/Boston & Albany Railroad properties of the State Line interchange yard.
The only prototype photo on hand that was captured during the era and season of the layout that includes the brook is the below Thomas J. McNamara photo from a 1952 New Haven fan trip to State Line. Although only slightly viewed in the lower right portion of the photo it represents the typical summer flow of the overall brook well and conditions observed personally during a Summer in the early 2000's.
The MAGIC WATER cured overnight to a slight rippled surface that was hoped for. Thankfully, no leaks throughout the curing process!
