As much as I hate the idea of Obama spending even more of my money, building up our train infrastructure can only have good long-term effects, in my meaningless opinion. I'd love to take a train instead of fly or drive for a long time... it'd be awesome if I could hop on a train to New Orleans instead of driving for 10 hours, or dealing with an hour or two of security checkpoints and another 2 hours in a plane.
Hell, our national infrastructure is in a mostly-crumbling state... bridges collapsing, highways constantly being "repaired" for 2 years, only to have to be repaired again a few years later due to the lowest-bidder shoddy workmanship.
I'd much rather sink 53 billion into infrastructure than into bailouts.
