What is a Stimulus pachage?

Ho can help you? Possibly. Find yourself a nice Ho and see if she can do anything. I'm sure she'll stimulate you.

Try looking into getting some venture capital or writing to the administration that runs Amtrak, http://procurement.amtrak.com/dbe-goals, or get a corporate lawyer to try and sell your work to a major railway corporation, CSX, etc....

A patent doesn't mean anyone will want to use it. It only means no one else can use it without paying you for some years.

Venture capital if you want to start and run the manufacturing process yourself. They will take a large share of the profits but you will retain some control.

Licensing if you want someone else to manufacture and you get royalties. A good lawyer is your best hope there.

Selling the patent outright for a lump sum. Again, you need a good attorney to make sure you don't sell it for less than it's worth.

You can try to get a small business loan to start a company but that requires you to do a business plan. Based on your writing here, you need professional help to devise a business plan which would probably involve giving someone a share of the profits for your idea.

Rusty - you got the patent from the USPO? It doesn't show up on their database yet, but it takes a while to update it. Congrats anyway.
We would be better able to advise you if you could post more about the technical details, similar to what's usually in the abstract, eg : http://www.patentstorm.us/patents/4355578/description.html
