Everything in the photos is included. Sound is not an issue. ① The parking lever doesn't engage properly, and the vehicle doesn't stop on the first try. You can stop it by repeatedly moving the lever a few times. ② The elevator can be raised and lowered, but it's a bit stiff, and it takes some practice to move it smoothly. I've also added the layout in the 7th photo, so please take a look. It seems the slope rail can be used in combination with your existing rails, etc.
