Yep.

No one (generally) bats an eye when voting at the city level for a $100mm road package.

But trains?

Freight should move mostly by train. We could build rail lines where there are already highways, just swap a vehicle lain for a train rail, all that 18 wheeler traffic can be reduced significantly.

Safer highways. Less congestion.

Not that simple, at least in the U.S. Rail has far stricter requirements on turn radius and grade. As an example the highways around here have 6%+ grade segments (after tunneling!) and rail is rarely over 1%. I haven’t even mentioned the incorrect subgrade and the massive safety envelope (approx 20x20 feet) which is about 2 highway lanes wide and far too tall for the thousands of highway overpasses.

Rail truly is a unique infrastructure concern and needs to be designed and laid on its own.

The requirements for rail depend also on how fast you want to run your trains.

Passenger trains typically (want to) run faster than freight, so the requirements are stricter.
