"Train tracks are dirty"
regarding dirtiness pollution-wise, trains can be fueled by electricity, while cars are mostly fueled by burning gasoline. car usage can increase emissions per person, making even diesel trains more efficient than cars.
"and loud"
the noise produced by passenger trains is very limited. high-speed trains are getting lightweight, decreasing the noise produced upon wheel and track interaction. maglev trains don't interact with the track at all, making even less noise. highways, in comparison, make a continuous droning noise with the occasional honking, crashing, emergency vehicle, truck engine, and sports car engine. once a highway is complete, that noise never goes away unless the highway is demolished
"not in my backyard"
freeways also take up more space than railroads do, but no one ever complains about that. many freeways have divided neighborhoods because of how impassible they are.
