Power lines are way worse than batteries IMO. You need literally thousands of miles of them for the freight network, which is costly. Much of which is extremely far from population centers (and the ability to repair them). Battery powered freight trains — swapped out at places near cheap energy, like random wind farms and hydro plants — could potentially be a leap in reducing the cost of freight.
