Energy Usage on the Subway

[Bolwerk]

It looks to me like the Subway's efficiency measures and higher
ridership figures have paid off since the mid-1990s. The NY Subway's
number was 3492 BTU/passenger mile in 1995.

Energy Intensity of Heavy Rail Systems, 2007

I'd really, really, like to see what criteria they used
to come up with that figure.

True. It should be broken down by peak and off peak periods at a
minimum, and probably by line or division as well.

Also, do these figures include only propulsion power or all power
consumption, such as station and tunnel lighting, pumps, etc.?

Certain systems are limited to shorter cars (like Chicago) which
aren't as efficient as longer cars.

As an aside, New Yorkers as a whole are the most energy efficient
people in the country. using less energy per capita than anywhere else.

SIRT has very few passengers and lots of miles?

Nice to see that PATH is also in the top 4.
