# Alan Schilke

Alan Schilke (/ʃɪlki/, shill-KEE) is an American engineer and roller coaster designer based in Hayden, Idaho, United States. He first made his mark on the industry by designing the 4th Dimension roller coaster, X2, while working with Arrow Dynamics. Schilke now works as a design engineer at Ride Centerline LLC and occasionally works with Rocky Mountain Construction (RMC).

## Education

Schilke got his bachelor's degree in civil engineering at Purdue University.

## Career

Schilke worked with Arrow Dynamics for many years working his way up to the role of head engineer. During his time at Arrow Dynamics, Schilke was credited as the designer of Road Runner Express at Six Flags Fiesta Texas and Tennessee Tornado at Dollywood. Around the same time, Schilke came up with the concept of the 4th Dimension roller coaster. This concept was criticised by his colleagues at Arrow Dynamics for being too extreme and impossible to engineer. The project only got off the ground when Six Flags' President Gary Story asked the company to develop a scaled-down prototype. This then led to the design of X, later renamed X2, which was installed at Six Flags Magic Mountain in 2001.
In December 2001, Arrow Dynamics filed for Chapter 11 bankruptcy, with the company being purchased by S&S Worldwide the following year. As part of the acquisition, Schilke (among many others) designed coasters for S&S Worldwide, heading up the wooden roller coaster division that produced four roller coasters in 2003 and 2004.
In 2006, Schilke along with Ned Hansen founded Ride Centerline LLC, an independent engineering firm in Hyde Park, Utah. Schilke continued to work with S&S and is responsible for the outward banking turn found on the S&S El Loco coasters such as Steel Hawg at Indiana Beach. In 2009 Schilke began providing design and engineering work for Rocky Mountain Construction, a company that specializes in the construction of roller coasters, water parks, steel buildings, miniature golf courses and go kart tracks. Schilke along with Rocky Mountain Construction founder Fred Grubb went on to design Iron Horse track (now known as I-Box track), an all-steel track replacement system for wooden roller coasters. The first installation of this track technology debuted on the New Texas Giant at Six Flags Over Texas in 2011.
In addition to providing designs for the amusement industry, Schilke and Hansen have worked with the Oceana Energy Company on the design and patent of water turbines to harness power from rivers and ocean tides.
