Night Shot of Southern Pacific Railroad Unit 1538

(Over-exposed print) Exhibit Q-12 was taken at night in the Mission Bay Yard. In Exhibit Q-12, the same engine is making a reverse move now with the engine crew looking out to the right of the picture where there is a public crossing which is heavily traversed. With such crossings, it is essential to have someone on both sides of the cab to observe approaching traffic from either side. Note also here the sign on the yardmaster's office at the extreme right hand portion of the picture: "A.B.C. Always Be Careful - The life you save may be your own."
