Fame
Fame? As a railroad inspector? Sorry, your career isn't exactly on the fast track to celebrity. Sure, some people in the railroad industry have become famous, but they're either the long-dead industrialists who built the railroads, or the probably-never-existed engineers, rail workers, and passengers of American folklore.
Inspecting tracks or trains for safety problems, you have about as much chance of becoming famous in this career as you do building railroads into space. It's just not going to happen in your lifetime.
