In any track with a train in it drive your truck exactly perpendicular to the tracks with your back tires resting on the rails. Wait until the the long train comes along (there are two of them, the short one is only like 5 cars long) and it should pass right through you. After the engines pass hold down the accelerator and as soon as the last train car passes through the truck you will go careening a hundred feet in the air!!! (The longer you can hold the accelerator before the jump the higher you will go)
