Road Runner Express is a steel junior roller coaster at Six Flags Magic Mountain in Valencia, California.

[7][10][11] On August 3, 2010, the Los Angeles Times reported "the junior coaster will keep the current red and black color scheme and stay in the same planned location in the northwest corner of the park but will likely receive a new name and theme.

[1][7] On January 18, 2011, the LA Times reported after considering a new theme based on DC Comics superhero sidekicks, the park opted for simplicity and would name the coaster Road Runner Express.

[13] Two days later, Six Flags Magic Mountain confirmed that the kid's coaster would be called Road Runner Express and that it would open on March 19, along with the revamped Superman: Escape from Krypton.

[2][15] This resulted with the Road Runner and Wile E. Coyote theme, rockets on the roller blade-style train, and Arizona desert background.
