How can Britain do crossrail for 18 billion? It's 80 miles of underground tunnels crossing rivers and preserving ancient and modern architecture with 40 stations and some of the most innovative technology in the world serving 200 million built over 10 years with out major disruption. On time and on budget. We have 20 miles of old technology over budget and it won't achieve it's goal. For 10.4 billion. Jeez.
