Where did you get these? I know from just glancing that New York and Chicago are far different than these numbers.

NYC has 887KM of heavy rail and Chicago has 332KM.

Heavy rail is not metro.

I totally agree!
Metro is no heavy rail, otherwise Chicago would easily win the total rail length if consider freight rail's heavy rail(Freight rail capital of the world!)!
How many hevy rail yards do NY has?
Chicago has 6 huge marshal-railroad yards in its metro! Just think how many miles of of rail these yards can rack up!

So i would assume that you are talking about commuting rail lengths so NYC is without a doubt US lengthiest commuter metro city!

AFAIK most metro systems would be considered heavy rail e.g. the New York subway or London Underground.

I was referring to "NYC has 887KM of heavy rail and Chicago has 332KM.", where in the 887 km are surely counted also some railways, that are no metro system (no, MetroNorth is not a metro, it's a railroad).

Be careful to not mix apples and oranges. Are we discussing "route-km" or "km of rail?"

The latter should be twice the former.

I noticed the question mark next to Baltimore's length, and if my memory serves me correctly, my hometown as a bit more than 45 miles. The heavy rail metro is 40 miles in length and the light rail is a bit difficult to discern. There are technically two separate lines, both about 40 miles each, but for the most part they run parallel, with the exception of a few miles at either end of the lines. So given that, the system could be roughly 80 miles in length, or if you cheat, 120 miles in length.

Right, rail length and distance length is different. If a system has four tracks in segments, it would count as more rail length, even though it's the same distance.

Very good point!
That easily explains why Chicago fall way short of NYC, becasue most of its rail are yards in distant.
I would say that Chicago is very close to NYC in the number of metro rail length.

Seattle is on the verge of building a 3.15 mile extension of the Central Link light rail system from Westlake to the University of Washington. The extension will add two stations to the light rail system. The tunnels will be entirely bored. The total cost is presently estimated to be $1.7 billion:

Seattle Central Link Univeristy Extension
$1.7 billion / 3.15 miles = $540 million/mile

New York is planning the 2nd Avenue subway. This will be an 8.1 mi. from 125th Street and Park Avenue in East Harlem to Hanover Square near Wall Street. The line will feature a mix of cut-and-cover and bored tunnels. The total cost is estimated at $16 billion:

New York 2nd Avenue Subway
$16 billion / 8.1 miles = $1.975 billion/mile

I believe there are other subways lines down the pipe in the country, at significantly lower cost. New York's cost is high in part because of hard rock, and in part because of really expensive property acquisition.

In Minneapolis, a 1.38 mile (7,300 ft) twin-tube tunnel (bored) was built recently for the Hiawatha LRT line. Earth-pressure-balanced methods was the type of boring used (not sure what that means).

The cost was $110 million. So that's about $79.7 a mile.

Here's a very detailed article on the construction: http://enr.construction.com/features...ves/021125.asp

How many stations will the Seattle project versus New York's project?

Stations does make difference.

Yes, **** you too! If you're not interested, stay out of the discussion. Or are all of your 400+ posts of the same tendency?
