Wow guys, sorry that some people actually care about the world around them want to learn new things rather than playing Call of Duty all day. McCoy created a special lubricant for railways and steamboats which everyone insisted on getting for their working station, ie; Railroad workers insisted on getting "the real McCoy", and wanted no substitutes. Without him, the railways would be created with delayed safety and enhancements, and no one would've thought of it till today.
And BTW, COD is a friggin fish, not a game.
