I don't want power windows. If the power goes out, the windows don't work. Very bad if you just ran into the creek.
My sister had a pickup with power windows. It also had broken inside door handles, so to get out, she had to roll the window down and open the door from the outside. The battery cable came loose, while she was in the car, and she had to break the rear window to get out. She chose that one because it looked cheapest to replace.
As for changing rails on that bridge, it wouldn't be much worse than spikes. No need to take the "tie plates" loose, just remove one bolt on each side, and move the clamp out of the way. The plates never move, so as long as the new rail is the same size, the gauge is already set, just drop the rail in and replace the clamp and bolt.
