I got this idea from Flight Simulator Prepar3D v4.5 from a payware General Aviation aircraft made by A2A Simulations. While you are in the cabin or passenger seat the camera shakes, vibrates, give you a G-force feedback which means you will see the camera being pulled back or pushed forward depending on the G-forces at the time when you throttle up. Very intense shaking effect when the aicraft starts, low speeds or when there is push and pull forces, In TSW the intense shaking effect should occur when you are at low speeds moving over rail joints but less intense at higher speeds however. During transit period you should have the camera move around "in a fluid" motion as the train sways left and right which is the left and right sides of the train moving based on what's happening outside which is simulated. Really would love this shake cam to take over the current camera because it's very stiff and there is no feedback at all, would make the experience one you'll never forget otherwise!
