Do-Dodonpa

When Dodonpa opened in December 2001, it accelerated trains from a standstill up to 172 kilometers per hour, or 107 miles per hour, in a scant 1.8 seconds.  This imposed over 3 g's on riders.  Stated another way, the trains experienced a forward acceleration that was over three times the force of gravity.  When the ride was modified and this loop was added in 2017, the initial acceleration was slightly increased as now trains are propelled out of the launch area after being brought to 180 kilometers per hour, or 112 miles per hour, in just 1.6 seconds.  The new launch profile briefly exposes riders to about 3.3 g's.
