Applying packet-switched networks to mobility networks will

Consider the 34-mile Sounder north line, which links Seattle to Everett. It was originally proposed as a six-train commuter service with six stops. But as costs shot up to $368 million from a projected $89 million, the agency cut back to four trains and four stations. About 1,100 riders use the line every weekday, far below the original forecast of 2,400 to 3,200 riders, for an average cost to the system of $330,000 per rider.


Sound Transit’s light-rail system, called Link, has also had its share of challenges. The 25 miles of light rail that voters were told would be completed by 2006 at a cost of $1.7 billion, have resulted in 23 miles of track which, when completed, will end up costing $5.2 billion.
