In America, the train hasn't been that vital to infrastructure since the era that inspired the trope. Trucks move 7 times more value annually [https://www.bts.gov/newsroom/2017-north-american-freight-num...].
If you live in a major urban area you'd never see it though because the intermodal facilities tend to be at or beyond the beltway (more efficient to truck the last 20-100mi).
Trains also do that with only 10% of the fuel [2].
I'm not sure what the table you link is showing. Is it $-km, or $-journeys?

doesn't make trains not vital.
