Every other major stop had wyes and engine houses that could be from two three and four stalls wide. The Anchorage roundhouse burned down in early 1951 and was destroyed. 556 sister to 557 survived the fire having been inside the roundhouse.   1016 was an ALCO RSD1 locomotive built for the U.S. Army in 1942 and was war surplus and given to the Alaska Railroad in 1949. The RSD1 was an export model of the RS1. In 1953 it was rebuilt into RF1B 1067. By the time 1016 arrived on the Alaska Railroad, the transition era was in full swing, steam was on its way out, and into history.   1016 is in front of an occupied stall, by an end cab switcher, either one of the SW1s, or possibly the lone Baldwin VO1000 1300. To the very left of the image we see an unknown RF1 unit which could be an A or B unit. RF1 locomotives were cowled (streamlined) RSD1 locomotives unique to Alaska. 1016 is freshly dressed in the original passenger scheme of blue and gold. Anchorage AK, 1949-1   The location of the roundhouse and turntable pit is around the area of the car shop's short conexes across from the steam track and close to the switch to the back shop. The pavement in that area is rippled for a reason!   - Commentary by Mike Gerenday
