A Father and Son Team
Since then Harvey and Dan have enjoyed several railcar excursions in New York and Pennsylvania. Harvey has taken the role of engineer, bearing all the responsibility of both operating the car safely and supervising his errant flag man, Dan. Dan basically does all the signaling work during a run, including flagging, ringing the bell, and blowing the horn. The horn irritates the engineer, so Dan likes it.
The D&H Railroad
Harvey and Dan have christened their hobby the "D&H Railway" which stands for Dan and Harvey. Harvey is the Chief Engineer, Dan is the President, and his sister Adrianne is the Queen of the Hoboes on the railroad. Dan is thinking of getting a railcar and keeping it at his place in California so they can have a western division of the D&H and make runs when it is cold back east.
