Thunderation is the steel mine train roller coaster that has been rattling riders through the wooded Ozark hillside at Silver Dollar City in Branson, Missouri, since April 10, 1993. Built by Arrow Dynamics, its stylized name, ThuNderaTion, nods to both TNT and the park’s 1880s mining theme — and it’s now entering its final season before a permanent closure.
With Silver Dollar City confirming Thunderation will shut down for good on January 2, 2027, interest in the ride has spiked: how tall do you need to be to ride it, why is it closing, what’s new at the park, and how do you plan a visit before it’s gone? This guide covers all of it.
Quick Answer
Thunderation is an Arrow Dynamics steel mine train coaster at Silver Dollar City that opened in 1993, reaches 81 feet and 48 mph, and has zero inversions. It will permanently close on January 2, 2027, after Silver Dollar City’s in-park storyline has the fictional Marvel Cave Mining Company reclaiming the land. Separately, the park is debuting a new MACK Rides family coaster called Miner’s Mountain Express in spring 2027, built in a newly created section called Daredevil Pass rather than on Thunderation’s former site.
Stats at a Glance
Park: Silver Dollar City, Branson, Missouri. Manufacturer: Arrow Dynamics. Opened: April 10, 1993. Closing: January 2, 2027. Height: 81 feet. Top speed: 48 mph. Length: 3,022 feet. Ride time: about 2 minutes, 10 seconds. Inversions: 0. Trains: two 6-car trains, 36 riders each.
The Ride Experience
Thunderation’s two trains wind through thick Ozark woods before diving into a tunnel and a sweeping double helix, logging nearly a full rotation of lateral turns carved directly into the hillside. Rather than climbing a lift hill right away, the layout builds momentum through terrain-following curves first, saving its chain lift for around the three-quarter mark of the ride — an unusual pacing choice that enthusiasts often point to as one of the best mine train layouts Arrow Dynamics ever built.
Originally, the third and fifth cars in each train faced backward, giving those riders a different view of the twists and drops than the rest of the train. Sometime after the 2010 season, Silver Dollar City reoriented all cars to face forward, standardizing the experience across every seat.
Height Requirement and Who Can Ride
Riders must be at least 48 inches tall to ride Thunderation alone. Guests between 42 and 48 inches may ride if accompanied by a supervising companion who meets the ride’s safety requirements. As with other Silver Dollar City coasters, standard restraint and health restrictions apply (no loose items, secure footwear, and typical pregnancy/back or neck condition cautions), so riders with specific health concerns should check the posted guidelines at the ride entrance or the park’s official ride pages before getting in line.
Why Is Thunderation Closing?
Silver Dollar City announced the closure on February 16, 2026, framing it through the park’s long-running 1880s storytelling: in-park lore says the fictional Marvel Cave Mining Company is reclaiming the hillside Thunderation runs through to resume ‘mining operations,’ effectively retiring the coaster’s track to make way for what the park calls the next chapter of that story.
The practical reason lines up with the ride’s age: Thunderation will have operated for 33 years by the time it closes, carrying tens of millions of riders since 1993, and is one of a dwindling number of Arrow Dynamics mine train coasters still running anywhere in the world. Park president Brad Thomas said Thunderation’s retirement would ‘launch new and exciting chapters in Silver Dollar City’s future,’ signaling this is as much about clearing room for new investment as it is about the coaster’s age.
What’s New at Silver Dollar City for 2027?
Silver Dollar City hasn’t announced a specific replacement for the Thunderation site itself; the park’s in-park storyline has the fictional Marvel Cave Mining Company reclaiming that land for ‘mining operations,’ but no new attraction has been confirmed for that footprint.
Separately, Silver Dollar City has confirmed Miner’s Mountain Express, a family coaster from German manufacturer MACK Rides (the company behind the park’s Time Traveler), set to open in spring 2027. Rather than taking over Thunderation’s old track, the new ride anchors Daredevil Pass, a newly created area of the park connecting the WildFire, PowderKeg, and American Plunge sections. It continues the mining storyline, sending riders through runaway mine cars dodging boulders and a flooded mine shaft while searching for a lost entrance to Marvel Cave.
Miner’s Mountain Express is billed as the longest family coaster in the Midwest, with more than three minutes of ride time, two lift hills, and around 15 airtime moments over more than half a mile of track — a notably longer and more elaborate layout than Thunderation’s.
Planning Your Visit Before Thunderation Closes
Thunderation runs through the end of Silver Dollar City’s 2026 season, with a planned final send-off on January 2, 2027. Like most of the park’s rides, it’s included with regular park admission — there’s no separate fee to ride it. Silver Dollar City sells single-day tickets, multi-day and season-pass options, and combo tickets that bundle in White Water, its sister water park, with pricing and availability shifting by season and promotion.
Operating hours vary by season and even by day, generally running shorter in early spring and late fall and extending into the evening during summer and major festivals, so it’s worth checking the calendar for your exact visit date. For current hours, ticket prices, and any Thunderation farewell events, check the official Silver Dollar City website before you go.
Thunderation sits in the park’s wooded mining-themed area alongside other frontier and mining-era attractions, so pairing a ride with nearby shops and shows makes for an efficient route through that section of the park.
A Branson Landmark Winding Down
For over three decades, Thunderation has been one of Silver Dollar City’s steadier thrill rides, prized for its family-friendly mix of speed and scenery rather than inversions or extreme height. Its mine train theming fits naturally alongside the park’s frontier and mining-era attractions, and its terrain-hugging layout is frequently cited by coaster enthusiasts as a high point of Arrow Dynamics’ mine train design work. Fans now have one final season to ride it before it’s gone for good on January 2, 2027.
Ride with your glasses on and keep them. Many parks allow glasses on rides if they're strapped, so check the ride rules first.
Small enough to ride with on most coasters, big enough for a phone, card and keys. Two zippers mean nothing falls out upside down.
A fan and a mist in one, rechargeable. Very popular in queue lines once the afternoon sun hits.
