Delve into the fascinating story of London's Post Office Tube Railway, an autonomous, driverless underground freight system that operated beneath the city for 76 years without public knowledge. Built in response to severe street congestion in the early 20th century, this innovative network transported millions of letters and parcels daily between central sorting offices and mainline stations. While its advanced automation and subterranean operation made it an indispensable part of Britain's communication infrastructure, especially during wartime, changing logistics and railway privatization in the late 20th century led to its eventual closure in 2003. Although much of the system remains sealed and hidden from view, a section beneath Mount Pleasant has been restored and opened for tourist access as part of the Postal Museum, allowing the public to experience this once-secret marvel.

In the 1920s, New York City faced a capacity crisis at Penn Station, leading the New Jersey legislature to form the North Jersey Transit Commission. Their 1926 report advocated for "through running"—a concept where trains continue through Penn Station instead of terminating there, improving efficiency and capacity. Historically, similar through-running solutions were implemented in NYC, such as by the Brooklyn Rapid Transit Company for the BMT Broadway Line and the BMT Nassau Street Line, and for Thameslink in London. However, current implementation at Penn Station faces technical challenges, including varying electrification systems, platform heights, and labor agreements between the MTA, New Jersey Transit, and Amtrak. The primary obstacle remains governance, with a lack of a single authority to mandate cooperation among these entities. Recent developments, including MTA head Janno Lieber's support for through running and the federalization of Penn Station's renovation under Andy Byford, suggest a potential path forward, with plans for a service optimization study to re-evaluate train operations.
