Most States are very similar , I believe the Full build for New York State which involves building at least 700 miles of dedicated passenger tracks , electrification , new bridges and upgraded stations + 300 miles of secondary track upgrades comes in at 15 billion. But is a drop in the bucket compared to the close to 30 billion in statewide highway and road projects.. Massachusetts has a 10 billion statewide Intercity rail plan but again its less then half of what the road projects cost..
