From my copy of the original Chama locomotive dispatch sheet:
Sept 15
St.S. (short turn service - aka Cumbres Turn)
Eng. Degani, Frm L. Shwcroft
Eng. C. Jack, Frm. Cunningham
Called for 830AM.
No locomotives numbers are noted. Also, the rest of the book is written in pencil. This entry is written in ink. Perhaps filled in later?
