This is likely not the best place to discuss railroad stocks. Go to
www.stockpickr.com or somewhere like that. I enjoy posting and reading here, but I don't always base my railfanning decisions on everything I hear here, and that involves the expense of an afternoon or maybe a drive in the car. I'm certainly not going to base decisions about my investment portfolio on things I hear here when it involves bigger money than my hobby.
Further, one number isn't going to determine the behavior of a stock, just the way the SD9043's success in the marketplace wasn't judged solely by it's horsepower number. Do at least 45 minutes of research/week for each stock you own or consider. Compare rates of return to competitors and similar industries and their stock prices. Look at who is investing in these stocks (Warren Buffet).
Conclusion: Don't base your investing decisions on what you hear at rr.net, and don't base them on a hunch or one set of numbers. Get your railfan info here, and make sure you have confirmation if you're driving far.
