Today I was reading about the Réseau express métropolitain and noticed the price tag. 6.5 billion. That's expected for a fully automated, driverless light metro, 26 stations, 212 pieces of rolling stock and all the other complex systems that make up the infrastructure. Just 6.5 billion for a system that crosses even more complex terrain (very large rivers - currently, 3km across the St. Lawrence which is about half as wide as Cambridge is as a city) and urban landscapes (a metropolitan area with millions of people) than the Cambridge line will.
Yet somehow the Cambridge line is going to cost 4.5 billion.
