Senator Chris Murphy is the author of various Buy-America bills over the past decade. It is one of his top priorities — and yet he can’t understand why HSR costs are so damn high:

This the same Senator who killed a plan by Amtrak to build a 30-mile bypass around the slow tracks along the Connecticut shoreline. The bypass would have reduced NY-Boston travel time by a remarkable 20%. Amtrak proposed building the route inland through open terrain, so as to keep construction costs low. However, the Senator demanded the route stick to the same curvy ROW where it will be very costly and complex to do any speed improvements.
If Senator Murphy wants to discover the reason US high-speed rail costs are so much higher, he can start by looking in the mirror.
