Head on train crash movie, on a bridge, derailment after collision, behind the scenes. HO scale fail

We tried to reproduce a spectacular and extreme accident: the ultimate head on trains collision of the Geoff Murphy's Under Siege 2 movie action scene and supervised by Richard Yuricich (the visual effects supervisor). We used 1:87 scale models freight trains and bilevel superliner passengers coaches for the derailment, and a 17 ft long 3D printed bridge, caught on 7 cameras ! Behind the scenes with real shots and raw footage, no CGI ! Casey Ryback (Steven Seagal) escaped just before the trains crashing and derailing ;) 0:00 Final rendering 0:19 Build the bridge 1:17 Tests with trains 2:02 Final preparations before filming and fails ! 2:30 Take 1 with multi-angle view, crash and derailments 2:57 Take 2 with multi-angle view, train wreck Bridge designed by me then 3D printed by: Miniature freight Southern Pacific train HO Scale : 4x locomotives SD40T-2 Athearn 10x custom tank cars Jouef Miniature Grand
