Unlike the vertical track used as a reverse point at one end of King Kobra, Arrow used loading platforms on both sides instead. At the end of the 1987 season, the ride was sold and relocated to Camden Park in West Virginia where it was renamed Thunderbolt Express. It was closed in 1999 after a circuit board malfunctioned and never reopened. It was eventually scrapped in 2004.

Ride experience

After riders board the train in the loading station, they are launched forward into an immediate drop. The propulsion system consists of an electric motor and pulley system. The drop leads into a vertical loop as riders experience a maximum of 4 g. The train exits the loop and ascends to a horizontal section of track similar in length to the loading station's track. After coming to complete stop for a brief moment, the train is launched in reverse to repeat the course and return to the loading station.
