No, you're not being picky, you're just wrong <eg>
The diesel is what moves the train. The generator/motor is just the
transmission.
Without the diesel the whole electric setup is worth just as much as a
gearbox without the engine.

About the same as a 30-year-old VW Rabbit diesel. Very impressive.

Yeah. That was a real non-polluter, wasn't it? Quiet too, eh?

We were discussing fuel economy, not "pollution" or "quietness," little one.
However having said that, you will find that today's diesels are much
more refined that those of 30 years ago, while still offering outstanding
fuel economy. (Of course you knew that, you were simply being disingenuous.)
All without hundreds of pounds of expensive batteries or a complex Rube
Goldberg drivetrain, and of course a properly-designed diesel engine will
run nearly forever by automotive standards.
To today's hybrids I say "Thanks, but no thanks." But I would certainly
consider a diesel.

Yeah, who cares about pollution and quietness, anyway. Buncha
God-damned treehuggers.

Meanwhile you'll stand on the sidelines and snipe? Thanks for sharing.
