This post: "The LA Herald say 1910-ish has an article about SP's trial of McKeen car trains [ motor+ 1 car] out of Arcade Station. That's another pic I wish I could see.", by Ed Workman set me to digging to see if I could find the pic he was looking for. I didn't find it, but did find this interesting article: [www.kcet.org], which begins:

"Before the Jet Age brought safe and comfortable air travel to the masses, most newcomers in Los Angeles arrived by rail. Train depots thus provided tourists' and emigrants' first introduction to Los Angeles, helping shape their ideas about the city. The city's grandest passenger terminal, Union Station, survives today. But its historic predecessors, which welcomed millions to the city, have all vanished from the cityscape."
