I recently discovered that the Mid-South chapter of the Railway & Locomotive Historical Society, centered in Birmingham AL, makes issues of their e-newsletter freely online after a year: http://rlhs.org/Chapters/msc/flyer.html There are several articles of Frisco-related interest, including articles about SLSF 4018 (Nov 2019), Frisco Memories at Memphis by Phil Gosney (Nov 2018), Pacing the Kansas City-Florida Special by Lyle Key (Nov 2017), and too many articles to count about the coal, iron ore and steel-related industrial and transfer railroads in northern Alabama. Happy browsing! (There's more info about the Mid-South chapter and the R&LHS here: http://rlhs.org/Chapters/mid_south.shtml. I'm sure both chapter and the R&LHS would appreciate some new members.)
