no argument that times are CURRENTLY good for rails, problem is the future. There is no doubt in anyone's mind that economy is slowing, and with that, rails biz will slow. Market is forward looking, not backwards looking. Right now, rails are priced to its peak, with a down-hill coming.
I'm not here to recommend what people to with their money, but its hard to justify any bright future for our economy.
Look at Gross and Buffet, both are bearish on US Dollar, which means that the USA will need to raise interest rates (further than people think) in order to attract foreigner to buy T-bond. Foreigners are putting money in Asia and Middle East, and if nobody will foot the bill for the USA debt, what happens...
Rails will be hit hard by any indication of slowdown... and it is imminent, you dont need a PHD to figure that one out
