What would be interesting to me would be a Seattle<->Spokane HS line. Maybe it could run along the Empire Builder route? The cities are separated by around 280 miles using I-90 and flights take around an hour tarmac-to-tarmac. If you flew tomorrow the flight would cost around $200 RT. But you have to fly via Seatac which isn't exactly convenient if you're going to the city. The Amtrak station is right downtown in both cities. Such a connection could bring some much-needed economic development to Spokane, and might even turn it into a bedroom community of Seattle for some people - the economics might work out considering that a $1M house in Seattle might run you $200K here.
