Non-railroad companies
Correspondents frequently ask me to expand my project in one direction or another. I fully understand their desires. My experience over thirty-plus years has proven that I must limit project expansion to railroads, equipment manufacturers and very closely-related companies. The most common reasons for excluding companies are:
- companies cannot be associated easily with railroading because they lack words like "railroad," "railway" or other common rail-related keywords in their corporate names, even those companies with certificates that show railroad vignettes
- companies require extended research to discover whether they were related to railroading or not
- companies obviously belong to industries other than railroading
- collectors of other specialties would be unlikely to look in this project for information about their certificates
Having spent in excess of a thousand hours researching and explaining off-topic companies, I finally compiled a set of Rules for listing companies for those collectors who want to see if a specific type of company might be listed.
I have also compiled a long list of specific companies (shown below) that have already been examined and rejected for listing. Multiple entries in the list below indicate references to:
- different companies of the same name
- multiple locations of the same company
- my inability to research and remove all duplicates
Please contact me if you have contradictory information that proves a company listed here:
- operated (or planned to operate) a rail operation in North America...
- which carried or intended to carry unrelated passengers or freight...
- for profit...
- from a specific point of origin to a different destination...
- across rights-of-way it did not own.
Utilities represent a special situation. Power generation facilities obviously belong to the electricity sector. And many utilities DID operate street railways and interurbans early in the development of the industry. Some, but certainly not all, operated profitably and otherwise meet my conditions for inclusion. However, determining which companies maintained their involvement in railroading for extended periods is highly burdomsome and far beyond the purposes of this project. Therefore, I include utilities only if they offered an indication of railroading in their names and I exclude them if they didn't. For a more exhaustive explanation, please see "Why not include utilities?"
I have used hundreds of formal auctions, online auctions, and dealer mailbids as sources for information about certificates. Information recorded includes combinations of descriptions, serial numbers, offer prices, minimum prices, prices realized, dates, and possibly images.
The list below shows every company that "sounds" like a railroads or someone has suggested for inclusion in this project, but which has proven off-topic for one or more reasons.
