Subway

Streetcars are a better option than Vancouver's proposed 2.8 billion subway, says Prof. Patrick Condon of the Design Centre for Sustainability at UBC.

A proposal to run a light rail subway through central San Francisco passed environmental scrutiny at the federal level, green lighting the project to move forward. Now all the $1.3 billion project needs is some federal funding.

In a trial run starting in December, monitors in one New York City subway station will display the exact location of every train on the line, giving riders a more accurate idea about how long they'll have to wait for the next train.

Stinky trains may become a thing of the past in Berlin, where officials are sniff-testing new fragrances to mask the odors of public transit.
