To produce the star trails I shot 300 frames each at 13 sec f/5.0 ISO 400 using a Canon 6D and Tokina 17-35mm lens. I then stacked the frames in StarStaX to produce the results seen here.
The ruins in the foreground are from an old railroad station, I believe.
The water tower dates back to the age of steam locomotives.
The San Diego & Arizona Eastern Railway Company is a short-line American railroad originally founded in 1906 as the San Diego & Arizona Railway (SD&A) by sugar heir, developer, and entrepreneur John D. Spreckels. Dubbed "The Impossible Railroad" by many engineers of its day due to the immense logistical challenges involved, the line was established in part to provide San Diego with a direct rail link to the east by connecting with the Southern Pacific Railroad lines in El Centro, California. The SD&A's 146.4-mile (235.61 km) route originates in San Diego, California and terminates in El Centro, California. Recently, the Baja California Railroad has taken out a lease of this line and plans to restore freight service in the near future.
