Located in the 42N's central part of the hawkeye state (Iowa) is the Boone and Scenic Valley rail line found at 42.04°N, 93.89°W. Behind a restored locomotive is the streamliner passenger car, the City of Los Angeles. The car was placed into service during 1936 on the Union Pacific line. Today you can take a ride on the car periodically.
While this passenger train won't be gone five hundred miles when the day is done, it is something that you can walk through, ride occasionally, and just guess how it felt to commute from coast to coast a half a century ago on the rails. Know that.
