In case you'd like to read some first person accounts of working for the Southern you might want to get a copy of this book. My only connection with the book is the fact that I own a copy. To give you some idea of the writing style I've included a brief quote in this post.
"At the Alexandria Station the main line tracks separated into freight train tracks and passenger train tracks. The freight tracks, behind the northbound passenger waiting room, went into Potomac Yard. One morning a southbound train stopped right in front of the passenger sheds to wait for clearance. From the Alexandria station past Duke Street was a long curve, and incoming freight trains had a signal just before they got to the Duke Street Bridge. Because of the curve, northbound engineers had to depend on their firemen to let them know whether or not the signal was clear. An RF&P freight was coming in, and when it got close to the curve the engineer asked his fireman how the signal was.
The fireman replied," I can't see the signal for that caboose is blocking my view." The engineer threw the brakes into emergency-too late! He rammed the Southern caboose and stood it on end. The flagman saw him coming in time to get out of the way. He took off down Duke Street. Someone stopped him and asked why he was in such a hurry. He pointed back toward the bridge; the caboose was on fire, and flames were going high above the bridge. Fortunately, the Southern conductor had already started walking to the front of his train when the train struck so no one was injured. There were some hard feelings however. The conductor had bought a couple of hams in Monroe and left them on the caboose. By the time he got back to what was left of the caboose, his hams were cooked well done."
