Have you ever said "interchange" when you really meant "intermodal"? We really can't blame you. Since American railroads have been around for over 200 years, many terms are so archaic and confusing, their original meanings are nearly impossible for the average person to infer.
Fortunately, Seminole Gulf Railway is here to help. We've taken dozens of the most common railroad terms and assembled them here into one easy-to-understand railway glossary.
