The New York system's express trains make it faster for long trips.
There are only two sections on the Underground where express and local
services are provided, and one of them is quite short. (You can see
them on the diagram, except that what it doesn't show is that as well
as bypassing the local Jubilee Line stations, some Metropolitan Line
trains bypass some stops on their own line too.) In addition, peak-
hour crowding sometimes makes for rather long station stops in London.

Double tracking also makes for easier rerouting in case of breakdowns.they can
switch tracks to avoid the breakdown. LU train breakdowns stall the entire line

.. In New York all stations are open all the time.

4 stations are not open 24/7 145th st and 148th st on the 3 line are closed
