Start by figuring out the path you want to travel on by train. If you are looking to take a classic train ride, then you might want to try the Durango and Silverton Narrow Gauge Railroad.
Use online companies such as Side Step and Travelocity. These companies will give you a variety of routes in Colorado to choose from. You can find many routes to take, whether scenic or in depth.
Purchase your train tickets in advance before you are at the station. The trains can fill up if you don't get on them in time or if they are running late. Be punctual and get there one or two hours before.
Book from a variety of train routes such as the Royal Gorge Route Railroad, which is one of Colorado's most scenic routes and is loved by many tourists. You can also take the Leadville & Southern Railroad, which travels over the Rockies.
Take modern day trains to specific destinations. The Amtrak California Zephyr line goes from Colorado to California, but it's a scenic journey west on a modern train line. You can also take the Ski Train, from Denver to Winter Park to ski in the winter or hike in the summer.
Book the San Luis Express if you want to explore the Colorado Rockies and see all of its beauty and wild and remote regions across the terrain. Visitors love to ride the turn-of-the-century vintage steam engine.
