On SASUKE Vietnam 3 , the Crazy Cliffhanger (called locally as Treo Người Trên Vách Kép) appeared as the fifth obstacle in Stage 3, replacing the Cliffhanger Kai (called locally as Treo Người Trên Vách) from the past two SASUKE Vietnam seasons. However, unlike in SASUKE/American Ninja Warrior, after reaching the end of fourth ledge, competitors had to grab a resting bar, which was a intermediate to the next obstacle (the Flying Bar ). Only Mat Redho attempted this obstacle in that competition, but failed while making transition to the final ledge.
With the Government of Salta as operator of the service, the Tren a las Nubes was announced to be running again by March, 2015,   although the service did not begin running again until 4 April 2015.

For that refurbishing, coaches were remodeled by the Province along with freight transport company Belgrano Cargas , while diesel locomotives were repaired at Alta Córdoba workshops.
