iPhone/iPad Train game

I wish to create an iOS game, my idea is inspired by an old DOS game from 1991. It is a Danish DOS game called "Guldkorn Expressen" You can try to play the old DOS games here: [login to view URL] (You use the arrow keys to drive back and forth, F1 to throw TNT to remove stones, F2 to jump over a tree, F3 shoveling mounds of earth away, spacebar to control bien, bien use to change tracks, fly bee across the track changer and press ENTER) The gameplay should be the same way, just adapted iOS (iphone and ipad) without the bee, because it not will work good, with touch screen. I only need a version with 2 levels. I will design levels, graphics and make sound The game is an old advertisement for a breakfast product, therefore the product as they gather up, be something else. I want it to be gold ingot as they gather up instead.
