Double Loop's support structure was originally painted white but would later be painted dark to match the track. The attraction debuted with two trains, one red and the other yellow. In 1993, the coaster underwent refurbishment adding some modernization to the control system. The outdated relay and photo eye controls were replaced with newer PLC (Programmable Logic Controller) and proximity switches to help improve reliability and to reduce downtime. Following Geauga Lake's acquisition by Six Flags, Double Loop was given a makeover in 2000, with a new paint scheme featuring a yellow track and purple supports. The yellow train was repainted a darker shade of yellow, while the red train was converted to purple.
