Dwell times are not the only reason to electrify. The post you reply to mentions another reason - reliability. DMs are more failure prone by design because they need to have both a diesel and an electric, and the fleet is smaller so it is harder to handle failure.

Plus environmental concerns, noise and exhaust.

Betya commercial power might be more polluting than newer generation diesels.
natives are really not looking favorable at sight pollution with poles and wires and 12,5 KV hanging within 18 feet of ground .

>>A lot of substations admittedly, but less of an issue with NIMBYs objecting to wires.

I would think the NIMBY's would be more opposed to third rail. After all, there is the danger of electrocution to children playing on the tracks!

The MTA's newest capital program includes a proposal to re-electrify some or all of the currently un-electrified segments of track 1 (the northbound express track) between Hastings-on-Hudson and Croton-Harmon. https://new.mta.info/sites/default/file ... Report.pdf Details on pages 29 and 128 of the PDF (which are listed as pages 27 and 126 by the document itself). Amazing how much time, effort and money transit agencies spend or consider spending just to restore infrastructure removed in decades past.

guaranteed the cost to restore is less than the 30 years maintenance they saved.

It would be great if all four tracks from Croton Harmon Station to CP13 had third rail. It would help provide flexibility, especially for the Croton-Harmon super expresses being able to go around another local train.

Absolutely. On the PRR the rule of thumb was that if a track was expected to be out of service for more than one year it was cheaper to tear it up and then put it back later if necessary.

Before thinking of going to overhead electrification, you need to check the clearances on the bridges, etc. along the Hudson Line. The amount of clearance required is actually very significant.
