A little help please.

I was reading through my emails and ran across this comment from Rev. Jackson who said this in a recent interview on Fox News in reference to semi auto handguns and rifles.

"But officer, I was just cleaning it when it went off"

"You know that these weapons can shoot down airplanes, they can blow up railroads. This is really a whole national security issue"
 Now I am fairly up to date on the damage most hand guns are capable of but someone is holding out on me, and I certainly believe the Rev. Jackson is not mistaken so someone please help me as to what rifle or handgun can blow up railroads ? I would like to get one before they are banned, you never know when it may come in handy.
Good info like this priceless.
