Whether these methods are easier I leave up to you:
1. Have a plating firm re-plate the rails. I would imagine that this would be quite expensive, perhaps more costly than replacing the damaged track with new track.
2. Overlay the rails with copper tape. Of course, this will not remediate the existing corrosion.
3. Remove the rails from the track, and refurbish them by hand. Loosen the steel tabs on the underside of the track. The rails will pop out of track. You can then clean both the outer and inner surfaces of the rails (I would not be surprised if the inner surfaces of your rails have corrosion, unseen from the outside). This will eliminate any chance of scratching the plastic. You will also obtain a superior repair. You might want to consider using a non-metallic "wool" material instead of steel wool, as this may reduce the amount of additional damage to the plating. Soak the rails in a corrosion inhibiting solution, wipe dry, and re-install. You will need to periodically apply a coating of the corrosion inhibiting solution to slow the advance of more corrosion (Rust Never Sleeps). This method works quite well, and the only cost is your time.
