In pulp you're always on the wrong side of the tracks.
We're train travelers. We love going places by that method. It's one of the perks of living in Europe. Therefore we have another cover collection for you today, one we've had in mind for a while. Many pulp and genre novels prominently feature trains. Normal people see them as romantic, but authors see their sinister flipside. Secrets, seclusion, and an inability to escape can be what trains are about. Above and below we've put together a small sampling of covers along those lines. If we desired, we could create a similar collection of magazine train covers that easily would total more than a hundred scans. There were such publications as Railroad Stories, Railroad Man's Magazine, Railroad, and all were published for years. But we're interested, as usual, in book covers. Apart from those here, we've already posted other train covers at this link, this one, this one, and this one. Safe travels. 
An American crime story.
Written by The Gordons, who were the tandem of spouses Gordon Gordon and Mildred Gordon, FBI Story follows Agent John Ripley as he investigates the disappearance of a woman named Genie. She's wanted for theft by the FBI, and by the Los Angeles police as a person of interest in a murder case. Ripley finds that he and the missing woman have a lot in common, a fact revealed by his perusal of her bookshelf and diary. Is she really a criminal or just a desperate woman in deep trouble? As the investigation unfolds and the search spans the entire United States, we learn that other people are after her, including a millionaire American fascist who looks like Hitler and rants about the master race. Eventually Ripley uncovers jewel thievery, treason, and the mysterious Genie herself.
Originally published in hardback on the heels of World War II in 1950, FBI Story delves deeply into the weariness and cynicism of combat vets, of which Ripley is one, yet all the agents are unswervingly dutiful and honest. Considering the fact that the novel is dedicated to J. Edgar Hoover, one could be excused for branding it propaganda. In fact, Gordon Gordon was an ex-FBI agent and had J. Edgar Hoover approve his work. Even so, FBI Story is generally considered a good read. It was later turned into a movie starring James Stewart and Vera Miles. The Bantam edition of the book is from 1955 with uncredited art, and the Corgi one appeared in 1957 with Mitchell Hooks on the cover chores.
