So you want trains right on your doorstep do you?

I'm amazed that is even a thing... the entire point of rail is that the train's path is constrained to the rails so they can be electrified by wire. Diesel-electrics are 30-35% efficient, electrics-by-wire about 95%.

The big issue is electric resistance. Rail is steel for strength. Wire is copper for conductance. Getting the power out along the many thousands of miles of rail is an issue. Do you want more California style wildfire power lines?
Oh and then power plants, some bright guy will just park the existing diesel electric generators (locomotives) to power the whole thing.
Consider with PSR there may be 10 power units on the consist at 2.5MW each, that's a lot of electricity that has to be delivered to some very remote places, especially with double track main lines.
Now factor in how many trains moving at one time, some educated guesses on the web say 5000 for the USA. So 5000 * 25 MW = 125000MW. Typical Nuke plant = 500 MW = 250 brand new Nuke plants. Even if off by a factor of 10, could the existing Texas power grid supply it? Oh and that brings up the grid itself and electric phase angle, as RR track goes everywhere the grid which is now in sections would have be synchronized nationally. Enron.

I think I'm beginning to understand why it exists and why the class one RR's are ordering a bunch of them. https://www.google.com/search?client=firefox-b-1-d&q=flxdrive+orders

These look good and I bet that they smell better too

I didn't smell good after getting shocked by the fence.
Capitalize on this good fortune, one word can bring you round ... changes.

A solution to Dull's main objection to electric vehicles.
swapping out electric car batteries

all I have to do is park on the designated markings and wait in the car.
I can hear bolts being undone as the battery is automatically removed from underneath the vehicle and replaced with a fully- charged one.
In less than five minutes, I'm ready to go again.

But then you could also opt for some real "gas" (not some misnamed liquid) and go hydrogen/electric with reports of around 1200km (745 miles) per tank being reported by some operators of our federal government Toyota/Hyundai hydrogen test fleet (I've been trying to find the link for that but ATM it's eluding my searches).

Dull, Here one for you then, assuming it is shipped to the U.S. or rebadged as a Nissan.
