That article doesn't link to the study and leaves out major questions about the methodology:

1. How did they decide that the benefits would continue over the course of 4 years?

2. How did they determine what "time lost" was? I imagine it's greater than just extra time waiting at the station. People probably also got lost trying to find a new way around, and were late to things important to them. Unexpectedly being late to a job interview is a very different kind of time lost than saving 3 minutes on your regular daily commute.
