I seriously doubt it pays for itself,but it may come closer to doing so than most others.
Ridership stats are pumped up since the Twins/Met Council offer discounts on game days which throws the ridership numbers off.
you are absolutely right, the only days that the choo-choo pays for itself are on football sundays. the ridership is minimal and most riders are subsidized as well. My house is less than a block away from a stop on the new line being put in. I will be moving as soon as possible.
