The phrase refers to the desire of individuals to locate and observe specially painted locomotives that commemorate the history and predecessor railroads of a contemporary rail line, specifically those operating in their geographic vicinity. For example, an individual interested in seeing a Norfolk Southern heritage unit would use the term to find information about the current location of these locomotives in their area.
The popularity of these locomotives stems from a combination of factors. The preservation of railroad history is a significant benefit. These locomotives serve as rolling tributes to the companies that shaped the rail industry. Enthusiasts find joy in documenting and photographing these pieces of rolling history, preserving visual records of a bygone era. The economic benefit, though indirect, exists as enthusiasts may travel to specific locations to view or photograph the locomotives, thereby supporting local businesses.
