Its late at night and 3rd trick Operator Clarence Nelson, father of Mark and Mike Nelson, taps back the orders he's just copied on his Form 19 pad, confirming the Dispatcher's intent. These were the days when timetable & trainorders directed traffic and kept trains safely on the move and apart from one another. Mr. Nelson hired on with the CNW in 1929 as the agent at Cuba City, WI., later in his RR career worked at South Janesville and Woodstock, IL.
