This route is basically a greatest-hits tour of Illinois geography, and winter adds a layer of sparkle that makes everything Instagram-worthy. Historic train depots in towns like Effingham and Centralia look particularly charming dusted with snow, their vintage architecture standing as monuments to the golden age of rail travel. There’s something wonderfully cozy about winter train travel. The Illinois Beach State Park area near Zion offers particularly stunning views where frozen lake meets protected natural areas. As you approach Aurora, the Fox River becomes visible, and in winter, this waterway creates some truly special views.
