I got tired of trying to match interactive rolling stock, industries, and commodities so spent some time putting together a matrix of rolling stock vs commodities and industry vs commodities. The base source is what came with 2006 plus a couple of downloads. The rolling stock vs commodity matrix has 181 cars/engines and is 6 pages in length. The industry vs commodity matrix has 86 industries and is 7 pages. Both these documents are Microsoft Word docs. If anyone is interested I can email them to you. My email is rnbariz@aol.com.
