Mandrill Mayhem Begins Testing

Chessington World Of Adventures
Saturday 18th February 2023

Big news coming out of Chessington this evening, Mandrill Mayhem the new B&M rollercoaster has begun testing and commissioning!


More photos and videos coming soon...


UPDATED 19th February - more photos and information


The first test began at 15:22pm when the train was launched backwards up the spike and then rolled back into the break run outside the station. Met with a huge gasp as we all watched on this might sound like not much but this is a huge step forward for the World Of Jumanji.


The train then reserved in and out of the station a few times as engineers worked out what we expect to be parking sensors and other technical bits.


We shared our video on social media last night but what we didn't say was that later in the evening the train completed the full layout, up the spike, through the inversion and up the helix!


The ride was only testing going up the spike 3/4 times and as we were about to give up and go home we waited for one final launch which just happened to be a full circuit test. The sounds this rollercoaster makes when it's testing is amazing, from what we can hear it doesn't sound like the ride is sand filed like other new B&Ms? The track doesn't have round holes in it like The Swarm at Thorpe Park does.


Very exciting times at Chessington!
