Railroading on the Tehachapi: A History of the Loop

It's easy to lose track of and even become bored with videos of trains going around the Tehachapi Loop. Much has also been written and said about the fact that is is an engineering marvel but I wanted to do something a little different.
What you don't see or hear a lot about is why it is here...I mean in this location. Why wasn't it built elsewhere? Why was it necessary? Wasn't there some other place the tracks could have gone and what about the kid and the mule?
I will touch on all that in the video so, join me for a history and explanation of the Tehachapi Loop.
