Right, that was the whole point. I think folks arent appreciating air resistance. The ISS is an example of what vehicles are capable of without it. Speeds incomparable to anything on earth, with little fuel usage. Its the largest source of inefficiency in travel. And the engineering science of reducing it is wholesale a scam for people.
The ISS travels at a constant speed in relation to the earth. People have to get on and off a train
Yes, acceleration is a thing, but trains a)reach a top speed and spend a lot of fuel maintaining it, and b)reaches much, much lower top speeds, with any effort to increase it requiring exponentially more fuel to reach and maintain. Air resistance is an absurdly important factor to travel efficiency.
I think a better example is airplanes. You run at high altitudes to increase efficiency due to reduced atmosphere.
