Try some of the other suggestions, especially the macro and tripod as those should work. Part of the problem could be what settings the camera is using. If you're in full auto mode, there's a chance the shutter speed could be very slow. If this is the case and slight wobble of the camera will make the photo blurry. Also, the camera could be setting a wide aperture, which reduces the amount of the photo in focus.
Getting as much light as you can on the subject can allow you to shoot at faster speeds, but if you use a tripod and timer, that should work as well.
In this photo it almost looks like the rear, right portion of the track is in focus (right under the barrel) and it could be the rest of the model is too close to focus. The macro mode could also help out..
