Cross-rail runs mostly on existing lines. Only 13 miles of the 85 total are new tunnels, so cost per mile is still almost a billion dollars.
(Being a bit unfair here, because the tunnelling cost is probably less than half the cost - the other half being rebuilding half a dozen massive underground train stations while keeping them operational.)
- orf 10y agoWhere did you read that? The project site says they have created 26 miles of new tunnels, also wider ones than ever before (6.2m). As well as 10 new stations. And all of this is slap bang in the middle of Europe's biggest city, which is pretty damn poorly laid out and not exactly conducive to huge scale construction projects.
- ptaipale 10y agoWikipedia says: "The project's main feature is 21 km (13 mi) of new twin tunnels." So that 26 miles counts the tracks both ways. Well, it's not a short way, 42 km is a marathon.
- orf 10y agoTrue, but it's not like building a dual carriageway where it's essentially one road split in two, it's two independent tunnels running mostly in parallel. I'd wager that's more than twice as hard to do.
