More completed rail line


  • Construction on the lower terminal building at the base of the coaster has begun behind the Adaptive building.
  • Concrete has been poured for the terminal building at the top of the coaster.
  • The first parts have arrived from Germany!


Construction process update:

  • Electric and water lines have been established.
  • Foundations for middle stations have been set; helixes and bridges are in progress.

We plan to pour concrete on the helix centers next week when the temps are less frigid. We will then complete drainage around the bottom terminal building area, which will enable us to start concrete work for the bottom bullwheel and bottom terminal building. We received confirmation this week that the first coaster parts from Germany are scheduled to arrive the week of March 21st, We're excited!

Here is what has been done so far:

  • Area has been surveyed.
  • 150 grade stakes have been set. 
  • Civil engineering is complete.
  • Coaster path has been cut. 250 trees have been harvested in a way to limit damage to the surrounding areas.



As many of you may have heard, we are currently in the process of building a mountain coaster! The loading area will be behind the Adaptive building. The coaster will operate year round and be a welcome addition to our lengthy attraction list here at Gunstock Mountain Resort. We are aiming to have it up and running by July 2016. What is a Mountain Coaster? Check this out:


We will update this blog post each time something significant happens with the build. Construction on the track itself begins on April 1st and is expected to take seven to ten weeks to finish.

The coaster will consist of two helixes and five bridges. There will be 40 sleds with anti-collision systems built in. The track consists of 53 individual concrete footings that must be placed within a one inch tolerance on the X and Y axis in their strategic locations. Using current GPS technology, we can pinpoint exact locations up to a half an inch! Fascinating stuff. Some of these footings are precast, others will be made on site at Gunstock. The ride will last about five to six minutes. This is what a helix looks like:
