really good question and along with it, just to be consistent, do we really need to go full highspeed? Staying at 120 mph on a dedicated line would provide a travel time of 1.75 hours including city entry and exit and assuming no intermediate stops. Would allow the use of the track for commuter trains as well, with the appropriate sidings of course, in the same manner that both Belgium and France integrate their intermediate traffic. What would the cost difference be and is the difference worth the dollars? And how much of that 60B. is for the feeder traffic? I believe that YC/EG would make an excellent initial HS by the way.
