"... but these are the people who built the railroad. Everybody takes it for granted, but these were real men, doing their jobs, trying to get a leg up in the post-war world. ...sweat and dedication to do a job correctly, because it was all done by hand. No calculators or computers. Paper and pencil. And perspiration.
In addition, many of these men had father's that were first generation immigrants who also worked the railroads. Many had no formal education or high school. Yet, through sheer will learned the complexity of the railroad facets from trackwork, signaling, orders, repairs, engineering, shop machinists, etc. on and on... A testament to their work ethic and determination.
