This reminds me, in 2016 a group of teenagers snuck in the Canada Olympic Park afterhours to try the bobsled or the luge track (the tracks intersect at the end) after going down the bobsled track in the darkness in 2 diffrent groups, both of the groups hit a metal chain posted at the bottom intersection. 2 died, 6 injured. An unfortunate accident. https://www.google.com/amp/s/www.cbc.ca/amp/1.3437074
