I personally use Deel so that as a one-person company I can access large group benefits. Using their EOR saves me about $5000/year on health insurance compared to an ACA policy.
(More examples are here and I think the styling bug isn't affecting this page: https://docs.mycoder.ai/docs/examples/ I will look into the bug you ran into.)
They're likely running the Dark Reader extension and turned it off for the site, but didn't refresh the page. The extension doesn't always fully reset when you disable it for a specific site. Reloading the page with the extension turned off fixes the issue, so it is not your site.
Trains have little friction on the tracks. That's one of the ways they are much more efficient than a car (with rubber tires).
If the moving friction is very low, it makes sense that not that much energy is used to move the train once it's at speed. Slowing it down would return some of the energy back (with the rest dissipated as heat).
Aerodynamic drag is proportional to cross sectional area. A train only has maybe 2-3x the drag of a car at the same speed, but it has on the order of 100 to 1000x the mass and momentum. It takes forever for drag to do anything to a train at speed.
