In my dreams, regulators would require UP and NS to divest older or redundant ROW so that publicly-owned transit systems can repurpose them for passenger rail services. Even so much as a single-track minor branch line could be reinvigorated with high-floor DMUs while maintaining freight access in the off-hours, such as with SMART in San Francisco area. And in the long run, electrification without UP’s typical objections to overhead wires could enable performant EMUs like with CalTrain.
