Probably depends on the specific route, but 200 cars doesn't seem unrealistic.

In their time, Siemens and Hertz had not even been added to the SI system yet, I imagine they would speak in terms of mhos and megacycles back then.
From a conversion the article uses I believe they are using the metric ton (aka megagram) which abbreviates to the lower case t. The article you reference does not seem to ever abbreviate 'ton' and I suspect that may have been done intentionally to avoid running into this issue? Its what I would have done, anyway.
I don't think this impacts the readability of your comment I just thought it was a shame that the other comment didnt go all the way and attempt to describe correct useage.
> we're still measuring disk sizes in half-kibibytes by default
Where do you see that? Marketing and operating systems always measure disk sizes in bytes (or KB, KiB, MB, etc.), not sectors. Only in low-level tools like some hex editors and disk partitioners do I see data measured in sectors.
> the sector sizes have actually been 4/8 KiB for years
512-B sectors for hard drives and flash drives, yes. But I'm too young to recall whether older hard and floppy disks had varying sector sizes. I can say, though, that CD's sector size is either 2048 bytes (data mode), 2324 bytes (XA), or some other value in other modes.
10 gigagrams. It's a rough estimate of 500 tons per story.
But tonne is a perfectly good "unit officially accepted for use with the SI". If you're willing to use "minute" and "liter" you should be fine with tonne.
Precisely where you've described; I've also seen "du" use it once, although it normally uses 1 KiB blocks (one of the very few things that I agree with rms on).
> 512-B sectors for hard drives and flash drives,
They've been using 4 KiB sectors since 2011; the 512-bytes sectors are emulated in the controller: [0].
P.S. "22 million pounds"? That's approximately 22 thousand half-tons or 11 thousand tons in sensible units. Then again, we're still measuring disk sizes in half-kibibytes by default even though the sector sizes have actually been 4/8 KiB for years...
