The April 1969track charts for Springfield ( http://www.frisco.org/shipit/index....minal-industry-schematics-april-30-1969.9913/ ) show the U.S. Post Office Annex on Jefferson was served by two tracks, a track from Mill ST. That had 4 spots and a track from Phelps that had 2 spots. I’m sure the tracks were no longer in use by this time ( they likely were not used after the Frisco exited the passenger business, and perhaps before that ). The question I have is when the Post Office Annex was rail served, what kind of cars were spotted there? Boxcars? Baggage cars? A combination of the two?
