Naming a RR is a tough thing to do. You want something fun, perhaps factual but certainly commanding. Personally I like whimsical names or names derived from twisting the owners names, the financiers names or the location. History shows us there were many RR’s were named for the towns/cities they served. RR’s in England have interesting names.
Here is my backstory. I struggled with names for mine and took ideas from when it was under construction and the fact that I had plenty of 3 things thusly the Rock Root and Dog Poop was born. The Dog was a bit strong so it was relaxed to PUP. I like names that cna be reduced to string of somewhat connected letters like The Rock Root and Pup Poop Rail Road. The RRPPRR is a barely making it tourist line that runs antique geared locos for tourist trains and occasionally freight. Coal was discovered so a shaft mine and processing plant was constructed. Along with the coal a vein of virgin pure Cape Cod sand was found so covered hoppers were constructed and a processing packaging plant was also built. The CCSSSCC was founded which stands for The Cape Cod Souvenir Sand Supply and Coal Company. On occasion the steamers from the museum are called on to haul a coal string to the interchange but this was found to be too expensive and the owners feared damage to the steam relics so a 2 diesels were leased from the CCC the Cape Cod Central which is a real life RR here on the Cape.
You can’t go wrong with Naming for location, destination or product hauled. Or how about the JRRRJ Which is the Joe Rusz Rail Road Junction.
