Under Siege 2: Dark Territory, Train Crash Sim

The ROBLOX Under Siege 2: Dark Territory. The trestle bridge scene is where the passenger train collided against the freight tanker train while on Trestle Bridge which creates a massive explosion wreck including a collapsed bridge where the several trains fell down the gorge. Now it's a scene game since the test has completed. I am trying to make the physics which is similar like a Movie. Reminder: Players can drive the train. The trains will have heavy damage if crashing. Trains from the Movie; Grand Continental Express (Passenger) Nevada Petrol Express (Freight)
