The Crossrail (Elizabeth Line)project in London is 118 kilometers long, including 42 kilometers of new tunnels and track and has numerous rail and subway stops. The total cost is 15 billion UK pounds. Which, per kilometer or per stop is a fraction of the cost of the one stop Scarboro line, not withstanding the fact that London is one of the most expensive cities in the world.  Someone is getting rich on the Scarboro line!
