In the early days, Eldorado had several railroads which came through town. It was at an intersection of the Louisville & Nashville and Cairo & Vincennes railways. The “eastern extremity” of the Belleville & Eldorado Railway (St. Louis Short Line) also came through town. According to Illinois Historian Neil Gale: “This settlement, by 1896, could boast of exceptional railroad facilities - The Illinois Central, The Louisville and Nashville, and The Chicago, Cleveland, Cincinnati and St. Louis. Like several other villages, when the railroad company placed the name on the station, the name was spelled Eldorado, instead of Elderedo, and it has been known by that name since that time.”
