Through the Ship on the Frisco FB page, I remade the acquaintance of a friend of my Mother. Sally's grandfather was a Frisco engineer with 52 years’ experience, and he was on the last scheduled run of the Chadwick mixed, which was known somewhat derisively as the Chadwick Flyer. Sally is very proud of her Irish grandfather's work on the Frisco, and she has done much to preserve his memory. She had many questions about the Frisco's Chadwick Branch, and after many email exchanges, I put this little piece together to give her a better idea of operations on the branch. It is written for the non-railroader, but those on this site may find it useful. My thanks go to Roger Taylor, John Sanders, John Dill, and Brad Scott from whose posts I took information or who provided me with copies of original source materials. Unless noted, the "Figures" are from my collection. This thread is dedicated to Robert Lyons, who retired Oct 1933. He is shown in Figure 2; the second individual from the right is Mr Lyons.
