That doesn't really contradict what that person was saying. They just said that only Americans call trains old fashioned. That can be true at the same time as it's true that American industry makes heavy use of freight trains.

The other reply to the parent comment give a link that ranks the US lower.

But whatever the actual ranking, the volume of rail freight is very high.

Here's a metric: remove iron ore/coal shipments that only use a single fixed repeat route on a decaying network at <10MPH on un-electrified rail that hasn't been majorly maintained in 50 years.

If you remove that particular outlier (that basically drowns out everything else), the US's rail is pretty trash.

Or look at coverage; US rail companies will abandon profitable routes because they're fixated on improving the average profitability instead of absolute profits.

Nobody who knows much about railways is impressed by the US's railway system. Electrification is cheaper in the long run, and yet the US railway system is <1% electrified, because it's not profitable in the short term and all the railway companies are horrifically allergic to anything that won't be profitable within the decade. The US rail system is slowly falling apart, because while it makes sense in the long term to maintain it, it won't earn a profit now.
