WHAT'S IN A NAME? Proper railroad names combine city names, directions, and destinations. Chicago, Lake Geneva, and Pacific works, as does London and North Western, Atchison, Topeka, and Santa Fe, and if you want to economize on commas, Chicago South Shore and South Bend. It is possible to achieve great economy, which Union Pacific, Great Western, and Trans-Iranian accomplish. Sometimes, a single word works. Pennsylvania. Ffestiniog.
Alas, modern business gurus, who insist on butting words together and inserting capitalizations in the middle (SouthShore -- I kid you not) come up with such clinkers as First Great Western and One Railway (hint: it does not -- yet -- refer to Norfolk Southern.) Michael at Transport Blog has a good dose of disdain for such efforts.
