I'm averaged in at around $25 a share. With reinvested dividends, I am up a total of 68% since 2007. I basically got in because I wanted to be deeper in the supply chain of railroads, which received a run up when Buffett bought into BNI. Incidentally, I also decided to buy into CNI, along with TRN.
For a good while, I've managed to buy TRN shares at a cheap PE, anywhere from 8 to 10. Hence, even a fair PE = 12 in contrast is raising my returns. I'd like to think that solid fundamentals might warrant closer to a 15 PE, which really would make this a superior investment.
I believe TRN will benefit because of the energy situation. One, we need to extract domestic tight oil & gas. Two, transportation in general needs the highest efficiencies, as energy still won't be cheap. More goods need to therefore be moved by rail. I am very optimistic.
