Though it has several key constraints, the Metrorail System’s capacity compares favorably with its peers and even out-performs them in several key measures.
In a previous post, we explained that Metro doesn’t schedule more than 26 trains per hour at any point in an effort to balance reliability with high capacity operations. But it also raises some interesting questions: How does Metrorail’s capacity compare to peers? How does Metrorail compare to its peers in terms of train throughput and what are the specific constraints that prevent trains from operating more frequently? Are there any ways to increase the capacity of the existing system beyond 26 trains per hour?
We developed a white paper (PDF) to answer those questions. Some of the findings might surprise some Metroskeptics or armchair transit planners, but Metrorail has among the highest capacity infrastructure in the industry, which – when in a state of good repair – allow it to outperform its peers in a number of key areas.
