The following video is part of our "Motley Fool Conversations" series, in which industrials editor/analyst Isaac Pino and research analyst Austin Smith discuss topics around the investing world. 

Today, Isaac dissects GE's various business segments, focusing on its fastest-growing business -- transportation. During the second quarter, the transportation unit reported revenue and earnings increases of 27% and 58%, respectively. Apparently, trains are really pulling their weight for the $200 billion behemoth these days. Keep in mind, however, that transportation is a relatively small segment of the company and only snags about 2% of the global market share. Still, railroad traffic is often a reliable indicator of global economic activity, so a steadily growing backlog reveals strength moving forward in this otherwise cyclical business. GE's stock has historically been tied to economic growth (it's more closely correlated with the S&P 500 than any other stock), but these days management seems confident in double-digit gains regardless of the dismal European economy. Find out in the video below why Isaac and Austin have both invested their own hard-earned cash into GE in recent months. 

For GE, the recent financial crisis struck a blow, but management took advantage of the market's dip to make strategic bets in energy. If you're a GE investor, you need to understand how these bets could drive this company to become the world's "infrastructure leader."
