Does anyone happen to know any particulars about AT&SF's apparent habit of giving away or selling off boxcars decades ago? I spent a bit of time out west recently and came across many repurposed 40' AT&SF boxcars, even a few in NM in people's back yards. As someone from the Northeast (where there aren't many towns with random boxcars in people's backyards), I am intrigued how this came to be.
