That makes it cheaper if you can use it: a railway track has 20 times the capacity of a freeway lane. (This is just the result of a basic Google search. It also says maintenance costs are "much less" for the railway.) There are probably economy-of-scale issue too (we build a lot more roads), and different expectations of road vs. rail safety (a rail accident with a few injuries has national media coverage for days, upgrades costing millions may be rolled out to prevent a repeat; every day several people die on roads, the infrastructure is rarely improved).
