US Rail Construction Costs | Pedestrian Observations

This is a placeholder post, in which I’m just going to summarize the costs of projects in the US and the rest of the world. I will focus on subway tunnels, but also put some above-ground rail for comparison. No average is included – all I’m doing at this stage is eyeballing numbers. As far as possible, numbers are inflated or deflated from the midpoint of construction to 2010, and exclude rolling stock. The PPP exchange rate is €1 = $1.25, $1 = ¥100. For now, only dense infill subways are included.

East Side Access: $8.4 billion; excluding preexisting tunnels, this consists of 2 km of new tunnel in Manhattan and a new connection in Queens. So this is about $4 billion per km. Update 6/21: the link here stopped working. Here‘s a slightly older link, saying the cost is $8.1 billion.

Second Avenue Subway Phase 1: $4.9-5.7 billion in 2007-17 for about 3 km of new tunnel. This is $1.7 billion per km.

7 Extension: $2.1 billion in 2007-12 for 1.6 km of new tunnel. Note that this has only one station, an unusually sparse spacing for a dense urban area. This is $1.3 billion per km.

Crossrail: £15 billion in 2008-18 for a line of more than 100 km, of which the primary component is 22 km of new tunnel under Central London and Heathrow Airport. Due to the extensiveness of the London Underground network, this is the most complex project on the list. The cost per unit of tunnel is about $1 billion per km, making this the only outside New York to cross the 1 billion line.
