This is the fictional (with probably autobiographical elements) story of Eddie Sands, a boomer, an itinerant skilled railroad worker who followed the development booms wrought by the iron road. Sands is a very skilled brass-pounder (telegraph operator).
The episodic nature of this novel is probably due to many of the chapters having been originally stand alone short stories (the novel as a whole was first published in 1942 while some parts had been published as early as 1936). Because of this, we do not really get a satisfying character development arc in the hero Eddie Sands. He pretty much "keeps on keeping on." You could make the claim that his attitude toward women changes over time. Maybe. This is a novel definitely set in a different time, in an overwhelmingly male dominated industry, so it shouldn't be judged on the merits of how it deals with women. I was actually pleased and a little surprised that there were a few strong female characters in the book. Racially and ethnically speaking, there were Native Americans and Mexicans mentioned as manual laborers, a "colored boy" as a servant and a minor character of a little girl who was "half Mexican." None of these characters were disparaged, but rather treated in roles that fit the much more limited opportunities of the time.
The best thing about this book is the fact that it is a mostly realistic, contemporaneous record of a time and industry that doesn't exist anymore. People don't talk, work, dress or play this way anymore. My favorite slang was the use of "pious" for situations for which we might say "righteous" or maybe meaning a situation without deceit, honest.
Hop on the "careless road" folks (just the men folk), if you don't want any entanglements or to pay for "the upkeep of a blonde."
