After the Southern Line was abandoned, we finally tried this routing on our final trip South, from New Jersey to Texas. After that, our single passenger moved in with us, and except for a wedding or two, the TX&NJ was decommissioned.
In retrospect, we should have just run this route all the time, because it skipped all of the Tennessee downpours, and it let us pass a couple of White Castles. Also, when you cross the Oklahoma border, you are a lot closer to Dallas than when you cross the Arkansas border. You always learn an important lesson late. Ironically, the engineer’s son lives just off this route in Ohio now, so we would have eventually required a spur – which is the Cedarville Line.
