Brill #215 was usually paired with trailer #304 starting in 1939. Trailer #304 was converted from a Brill Model 75 (No M107) in 1939.   While you cannot read the number in the photo I believe this is #215 with Trailer #304 in Whittier during the W.W.II.  (See Prince ARR page 1023)  This photo would have been looking North West back toward West Camp and the Tunnel from about where the train station was located.    All the fill and docks had not been placed behind the train as of the date of the photo.Whittier, Alaska, 1944-45
