Amtrak is buying brand new Diesel locomotives for the Empire Services, NYP-ALB, with batteries for propulsion in tunnels under NYC. Why electrify a rail line when there will be no locomotives available to run under them.
Electrifying the SPG line is also not needed because the brand new electric locomotives Amtrak is buying is also a diesel locomotive.
California's Surfliners have also received brand new diesel locomotives. These locomotives have a 20-30 year lifespan depending upon how well they will be maintained.
There is a difference between nice to have stuff and need to have stuff. It seems Amtrak has already made the decision to run Tier 4 diesel locomotives everywhere there are not existing catenary wires above. ie, it is cheaper to buy dual mode locomotives than physically electrifying the corridors. Which sort of makes this entire thread moot because Amtrak has already decided and committed to a different future.
Additionally, Southern California (SB-LA--SD) got heavy snow last night and are experiencing power outages today. Shucks, they have power outages anytime during a year. Do you really want to rely upon a shaky power grid to power your trains?
Well, here's the thing, and I'll point you to the ICT procurement thread. Amtrak is getting diesel/electric because of said shaky power grid. They want to have the diesels as a back-up.
Does this mean we don't need to electrify lines?
Oh hell no, we definitely still need to!
Think about it this way: Diesel is $4.09/gal when I checked yesterday near BWI Airport. I'd imagine it'll be maybe more expensive for a diesel engine hauling 10 full passenger cars due to formulation, but buying in bulk and way in advance will bring that cost down.
Meanwhile, renewables are gaining traction and different types of diesel are being made. Diesel from crude oil does have limits on how much is available in our planet.
So why not stretch the chemical consumables for as long as we can?
The point here is don't settle for one or the other. Get yourself in a situation where you can use what you can get, and aren't stuck on one or the other. Amtrak saw this, and thus getting diesel-electric.
