I'd be interested in seeing a better comparison - it seems odd to compare a metro commuter rail vs. one stop through one of the most congested, densely populated infrastructures in the world. Presumably there are economies of scale at building a long metro commuter train that extends aboveground outside of the city. It's hard to compare construction and maintenance costs between two different cities where one has 30% more track and 10x the square mileage AND is 24hours in operation.

Building underground in the most congested, densely populated infrastructures in the world? You mean like the undergrounds of Hong Kong ($500M/km), Fukuoka ($300M/km), Singapore ($500M/km), Cairo ($300M/km), Sao Paolo ($250M/km) and Seoul ($100M/km)? https://pedestrianobservations.wordpress.com/2013/06/03/comparative-subway-construction-costs-revised/ https://pedestrianobservations.wordpress.com/2013/06/03/comp... (Admittedly, one of the Sao Paolo lines is 16% above ground.)

  But the cost of labor in those countries is much lower than in the US, no? (It actually makes sound $1B/km in the US sound way better than $500M/km in HK.)

    GDP (and thus wages) in Singapore and Hong Kong are pretty high. If they can get cheaper labour for construction, than only because they make it easier to import cheap labour, because they have saner visa policies.

    On average, no. If you adjust for PPP (as my source did), Hong Kong and Singapore are wealthier than the US. https://www.google.com/publicdata/explore?ds=d5bncppjof8f9_&ctype=l&strail=false&bcs=d&nselm=h&met_y=ny_gdp_pcap_pp_kd&scale_y=lin&ind_y=false&rdim=region&idim=country:HKG:SGP:KOR:USA&ifdim=region&hl=en&dl=en&ind=false https://www.google.com/publicdata/explore?ds=d5bncppjof8f9_&... However, due to exceedingly powerful transit unions, labor costs are higher in the specific case of infrastructure. As I said, waste.

  I feel like you took only one part of my comment to disagree with out of context with the rest- I'm not even disagreeing that the MTA is inefficient, I'm just saying that by looking at only one data point (cost/mile), you're disregarding many others. I think NYC is a bit of a perfect storm situation: - 24 hour operations - High labor costs, coupled with strong unions - Legacy infrastructure to maintain (vs. new subways) - extremely dense infrastructure to manage (NYC under-street infrastructure is famously messy/complex) - Huge distance of track to maintain - Large square mileage of city area to contend with Surely this has to play a big part in the cost of building subways in NYC vs. simply, "The MTA wastes money"?

    While size and square mileage would make things worse per km (or per km^2), they shouldn't affect unit costs.

I don't understand why you disagree with my use of the word "waste" to describe this.
