A few views along the Denver & Rio Grande Western Tennessee Pass Line, mothballed 1997 by Union Pacific because after multiple mergers they had 4 lines across the Continental Divide, and sending transcontinental freight though the middle of the Rockies didn’t really make sense.
Malta, where the branch to Leadville (right) split off from the main line at 9593 ft. Elevation.
The valley of Tennessee Creek north of Leadville.
A signal waiting in vain for a train on the southern approach to Tennessee Pass.
The tunnel (10,221 ft.) on top of the pass, crossing the Continental Divide.
The line crossing under US 24 (on the arch) and Water Street in Red Cliff, CO, 8,750 ft.
If Colorado cared about making tourism sustainable, this line, running through some of the most spectacular landscapes in North America, passing near major tourist destinations like Salida, Leadville, Vail, Avon, Glenwood Springs, and Aspen, would have electric passenger trains.

Transit modes can be used in very different ways. It’s easy to say “city X has a metro” but that does that mean? Here’s an example from the Nordics— three metros with different purposes.

Stockholm’s metro was designed to replace its streetcar network. That means multiple lines through the city, putting essentially all of the urban core within walking distance of a subway station. Image
They also expanded out to newly built suburbs, but always focusing on dense areas. Some old streetcar lines were kept and upgraded to light rail standards to serve lower density suburban areas. Image

Transit question for debate: is this one station or two? Image
TriMet says it’s two — “Gateway/NE 99th Transit Center” and “Gateway North.” And that makes some sense — there’s one set of platforms right next to each other and another platform a distance away. Image
But the distance between these two stations — 400 feet platform to platform — is less than the length of a single subway platform in DC.

In January 2004, Houston opened its first light rail line. At 40,000 weekday riders on 7.5 miles within 3 years of opening, Houston beat every other US light rail system except Boston and San Francisco (which has a 100 year head start) in riders per mile. Some lessons: Image
CONNECT CENTERS. The Red Line runs through the heart of Houston’s two busiest centers — Downtown and the Texas Medical Center. It goes where the people are, and attracted even more activity. Through Downtown, Midtown, the Museum District, and TMC it’s surrounded by new buildings. Image
SERVE ALL KINDS OF TRIPS. It goes to lots of jobs, but also carries lots of other trips to destinations like universities, hospitals, government offices, stadiums, restaurants, museums, and parks. That leads to ridership all day, not just at rush hour. Image

Houston neighborhoods have been dealing with trains blocking crossings for decades. Happily, elected officials are paying attention. But many of the solutions I’ve seen don’t get at the real problem. So here’s a primer on Houston freight rail. A train curving through a r...
Houston is one of the biggest freight rail centers in the country. Because of our huge petrochemical plants, port, and big population, a lot of freight goes to or from here. That means most trains in Houston aren’t just passing through — they’re serving Houston. Aerial view of chemical plants
Nine main lines converge on Houston. Many of the trains on those are headed to the major yards, where containers are loaded and unloaded and where trains of chemicals, lumber, and other cargo are sorted in their way to or from industries. Map showing rial lies from ...

A few thoughts on electric buses, and why conversion to electric is not as simple as it seems. Two buses in a convention hall; from one says “100% electrRow of buses in front of a city skyline.
It makes sense that elected officials, advocates, and agency leadership and agency leadership are pushing for electric buses — in addition to the climate benefits, they’re quieter and don’t have any exhaust fumes. Aerial view of a bus in a neighborhood and a park.
Electric buses aren’t the most effective way for transit to help the climate — getting people out of cars is. And riders care about how often the bus comes and how reliably it operates, not the fuel it uses. Still, there’s no doubt electric buses are good. View of a crowd of people boarding a bus.

A southbound SEPTA Regional Rail train curves from the original 1890s alignment into Reading Terminal and onto the 1980s alignment into the Center City tunnel.
The old viaduct is now overgrown alongside the ramp leading into the tunnel.
The old viaduct and the tunnel end up in the same place — Jefferson (formerly Market East) station is right under the old Reading Terminal — but the new line runs east-west rather than north-south in order to tie into the old Pennsylvania Railroad Suburban Station.
