The information in the book was up-to-date as of December 2017. This page has updates since then.

5: San Francisco

eBART (p. 90) opened in May 2018. Ridership is over 7,000 on an average weekday. At 700 boardings/mile, this makes it a high performer along commuter rail lines.


6: Boston

The Silver Line BRT extension to Chelsea (p.98, right) opened in April 2018. It has a 1.2 mile dedicated guideway extending north from the airport, improving transit to a sense neighborhood previously served only by local buses and commuter rail.

On page 23, a map of Quincy Adams station shows how a locked gate limited access to the station. That gate is now open.


The TexRail commuter rail line opened on January 10, 2019. Current schedules are hourly from roughly 4 am to midnight, 7 days a week.


The SEPTA regional rail system is 280 miles, not 323 miles as shown, which means the ridership per mile is 408 instead of 354. As shown, it is a high performer among commuter rail systems; on the chart on page 16 it ranks just above San Diego’s Sprinter.


The Center City Connector between the First Hill and South Lake Union streetcar lines (p.138) was under construction in late 2017, but Mayor Jenny Durkan, elected in 2017, put it on hold. It now appears that the project will be built, but a gap in funding will need to be filled first.

The South Bay Rapid project (above), due to open in 2019, includes a 5.25 mile BRT guideway with 5 stations. Most of the guideway is in the center of suburban streets, but there is a short off-street section with a bus-only bridge. These will be used by a new 26-mile “Rapid” route that runs from Downtown San Diego, down HOV lanes on Interstate 805, through suburban single family neighborhoods, into the middle of a mixed use “town center” area, and on to a new transit center at the Otay Mesa border crossing.

22: St. Louis

The oft-delayed Loop Trolley, originally planned for 2014, opened November 16, 21018 (after a final one day delay) but with only part of the 1.9 mile route in operation since the University City has not granted a permit for the portion of the route within its city limits. The route is currently operating only four days a week, afternoon/evening only, so it does not meet the book’s standard of “transit.” Original plans called for longer service hours.

23: Pittsburgh

The frequency map in the book incorrectly show the entire light rail system as frequent service; the Overbrook and Library lines only have trains every 30 minutes at midday. A corrected map is to the left.


The Utah Valley Express BRT line opened on August 13, 2018. It runs through downtown Provo, around the Brigham Young University campus, and to Utah Valley University in Orem, connecting to FrontRunner commuter rail station at both ends. Half of the 11-mile route features dedicated lanes.

30: Milwaukee

The Milwaukee Streetcar, now branded “The Hop,” started service on October 2, 2018.

31: Austin

The map on page 203 has a production error on the author’s part — the streets are shifted relatively to the transit routes and river. Here is a corrected map:


Megan Berry (p.207) left office in scandal in 2017, and the referendum she had been championing was voted down by a 2-1 margin in May 2018.


The Hartford Line commuter rail started service in June 2018.

37: Oklahoma City

Oklahoma City Streetcar service beganDecember 14, 2018.

42: El Paso

El Paso Streetcar service began November 9, 2018.
