That's exactly it. It's not because of some cultural bias or whatever.
I'm in Japan. I use trains because it's so very easy and it's so very reliable. It's simply the best option for travelling. If I wish to go to Tokyo? I check a website quickly, I look up the best connection for my schedule (easy to find), I may pay in advance, or not. I take my bicycle and go ten minutes to the nearest station, park the bicycle in the bicycle parking there, and off I go. As it's a small station I change to a limited express train (where I've booked a seat) after ten minutes, then, after another forty minutes I reach a big station and I switch to the Shinkansen and I'm off to Tokyo. I'm relaxed all the time. I buy a coffee on the train, and/or I buy coffee and lunch at the station and bring on the train.
Every other way of getting there is way more complex, and would take way more time.
The US had to fill a huge area in the railroad era. That left a lot of underutilized track once the road network got good.
I'm mostly in favor of privatization, but this is an example where the local government provide an exceptional service which is in no way inferior to the privately operated ones.
The UK is so far gone that the transport authority in it's largest city can't revamp stations or do add-on development without literal years of hand wringing. And even then it's often rejected or reduced in the end.
Like: you can actually change the lightbulbs for the headlights of the Series 0 train while it being underway - there is a service hatch that opens to a human-sized service area accessible from the driver's cabin which allows such repairs.
Knowing the author I knew it was going to be his main argument before even opening the blog post. And it's obviously wrong, these companies don't compete with one another, they all have a local monopoly. (The article itself acknowledges that and even acknowledges the organizational benefits of such monopolies, but the author could refrain himself from praising the virtue of competition nonetheless…)
Sometimes fewer than 100 meters apart. Or connecting to each other's with a bridge.
Maybe it's a carry on though "This is the third article we have released from Issue 23".
