Chicago CTA near Berwin Station on the Red Line. The Purple Line runs parallel express all the way to Howard, skipping 13 stations. (By the way, I've always thought they should have just one transfer station about half way, but even now that they are re-constructing most of this section with new track and refurbished stations, a transfer station is not in the plans.)

Only two pairs of track end there, one used by the 6 train (green), and the other by the E train (blue). You can see it in more detail here:

http://www.cityrailtransit.com/maps/...subway_map.htm

There is 10 pairs of tracks coming from Midtown, and 7 continue to Brooklyn (not counting the lines used by the J/Z and the L trains that come from the side).

It's amazing that in Midtown Manhattan there are 22 parallel tracks (including PATH) going from downtown to uptown in a space of 1200 meters.

Indeed the section before and after Nam Cheong Station has 6 parallel tracks, 2 for each line (Airport Express, Tung Chung Line and West Rail Line) with tracks of West Rail Line are at-grade but covered.

This would not be possible without the tried-and-true "cut and cover" method of construction.

Rotterdam: Near Kralingse Zoom and Capelsebrug (though not in between), a spur at Blaak station (3 tracks) and of course centraal station (which is a terminus). Amsterdam near Van der Madeweg and Zuid station have short four-tracked stretches.

But if you want some serious work: try the Paris RER, though not fully a metro this thing has many parts with three or more tracks. And probably some cut-and-cover stations in the Tube.

Prohibit the construction of new single-family dwellings without stacking apartments in Amsterdam (A10), Rotterdam (motorway ring), The Hague, Utrecht (outer ring), Eindhoven (ring), Tilburg (ringbanen) and Groningen (provincial ring)!

And prohibit the use of agricultural land for new dwellings!
