Taylor Yard, Los Angeles
November, 1977, and a hot Santa Ana forces the crew to prop open the door with a broom while the old Cadillacs switch the hump. I was on the pedestrain bridge that crossed the yard, little kids in tow so no one would yell at me to get the hell off.  When the  big engines passed underneath, they'd give you a heady dose of diesel that would last you a week and get the kids jumping up and down.
