Metro is taking disciplinary action against half its track inspection department. Late-night trains will not return until July 2019 at the earliest. Will the new year usher in a season of festivity and goodwill to all riders?

WAMU's Martin DiCaro commutes with Metro's GM; we talk with a transportation expert about the impact of the rail system's impending hour cutbacks.

On this week's podcast, we talk Metro's steps toward reducing service hours, a Silver Line throwdown and Metro General Manager Paul Wiedefeld's first year on the job.

Red Line commuters can be thankful that the 10th SafeTrack surge is winding down. But the month-long rehab project, which shut down service along Fort Totten and NoMa/Gallaudet, highlighted how disruptions in a small corner of the system can have dramatic impacts on daily commutes.

The president-elect's promise to spend $1 trillion on infrastructure improvements is emerging as one of the least divisive aspects of his agenda, at least at this early stage. Will the Republican-controlled Congress go along with it? And would any of the money help WMATA?

Buckle your seatbelts, because where we’re going, there are no roads (or single-tracking). We consider two potential scenarios for Metro in the years ahead.

Want to hear something really scary? Metro’s 10th SafeTrack surge is hitting its most heavily trafficked artery, shutting down two stations on the Red Line between Fort Totten and NoMa/Gallaudet. We take a horrific bus bridge on the first weekday of the surge — and we explore the hidden force behind Metro: electricity.

Permanently ending late-night service. Temporary shutting down stations with low ridership. Many of the ideas for fixing Metro’s ills raise questions of fairness: Are the burdens of the SafeTrack era falling too heavily on lower-income communities? We ride the rails with Democratic Rep. Gerry Connolly of Virginia to discuss those issues and more.

When it comes to Metro politics, the most important thing isn’t party lines — it’s regional lines. We talk to a WMATA board member from Prince George’s County about the view from the east side of the region, and we look at where Virginia, Maryland and D.C. leaders stand on a key question: How can Metro get an infusion of funding?

Why are there so few seats on Metro platforms? How did D.C. home-rule advocates impact the historical trajectory of the rail system? Why are there only two tracks in Metro tunnels? Zachary Schrag, author of The Great Society Subway, joins us for a live recording at Kramerbooks in D.C.

As playoff baseball returns to Washington, D.C., thousands of Nationals fans could face a choice: Stay for the end of a game, or leave early to catch the right Green Line train? Also, we discuss the acute misery of Blue Line riders: New data suggest their Metrorail experience is the worst in the system.

More than a decade ago, a top Metro official warned of the potential for a "death spiral" involving a confluence of maintenance problems, budget pressures and rider dissatisfaction. Chris Zimmerman was on WMATA's board at the time, and he explains why those warnings went unheeded. We also ask three Metropocalypse listeners about their experiences using the rail service.

WMATA regularly gives itself a report card called Vital Signs, and the latest has some good news about railcar reliability, but bad news about on-time performance. We also discuss what Metro riders really want, and whether the U.S. has the desire and will to build high-speed maglev rail lines.

We talk to Metro Board Chairman Jack Evans about what he wants to see as the transit agency tries to fix its infrastructure and its culture. We also hear more from the man in the middle of it all, General Manager Paul Wiedefeld. And who's that coming from the train speakers? Nina Totenberg?

We walk through all the ways Metro is having a bad summer with Politico's Lauren Gardner, Greater Greater Washington's David Alpert and members of the Metropocalypse Facebook group. There's also bonus appearances from public radio luminaries.

Next time you're in an underground Metro station, look up and around. Are you in a calming streetscape setting? Or does it feel more like an interstellar battle station? Historian Zachary Schrag discusses the architects’ original intent.

As the bad news keeps coming for WMATA, we've been thinking about how Metro's woes compare with those of older systems. Kate Hinds, who covers transportation for WNYC in New York, reminds us that every city's subway has its strengths and weaknesses.

Rep. Barbara Comstock discusses how changing the pay structure for Metro's unionized workers could help the transit agency close up some of its budgetary holes. And Jackie Jeter, president of Amalgamated Transit Union Local 689, offers a counterpoint from the perspective or organized labor.

Why is the air conditioning so bad on some Metro cars? And what, exactly, is happening out on the Orange Line tracks during SafeTrack surge No. 5? Martin Di Caro goes looking for answers.

Martin Di Caro and guest co-host Lauren Gardner of Politico take a bus bridge with Rep. Don Beyer and encounter a bottleneck along U.S. 1. Come for the conversation about politics and policy — stay for the impressions of Robert Duvall and Marlon Brando.

In front of a live audience, we nerd out on questions about ridership and "death spirals;" expansion plans and bus lanes; and the 1990s technology we can't seem to escape.

Greater Greater Washington founder (and fellow transportation nerd) David Alpert tells us about his website's MetroGreater contest. We answer hot questions from Metropocalypse listeners. And experts on the psychology of commuting explain how SafeTrack might affect Washingtonians' habits.

In the latest Metropocalypse, we explore the future of Metro: What will the system look like in 10 years? Should responsibility for running the system be passed off to the private sector? How will the introduction of driverless cars and other technologies impact the system?

In 1986, a federal official issued a warning: If Metro continued to expand rapidly, the system faced a future of stark choices over maintaining existing infrastructure. Metro chose expansion. We talk to a historian about that decision. We also hear from a former Metro general manager about the following years, and from an Arlington planner about measuring how riders are responding to SafeTrack.
