Uptown Hudson Tubes

Uptown Hudson Tubes is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Uptown Hudson Tubes rather than just read about it. In short: The Uptown Hudson Tubes are a pair of tunnels that carry PATH trains between Manhattan, New York City, to the east and Hoboken, New Jersey, to the west. The tubes originate at a junction of two PATH lines on the New Jersey shore and cross eastward under the Hudson River.

Key takeaways

  • Uptown Hudson Tubes belongs to engineering; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Uptown Hudson Tubes to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Uptown Hudson Tubes from memory before moving on to harder problems.

Reference excerpt

The Uptown Hudson Tubes are a pair of tunnels that carry PATH trains between Manhattan, New York City, to the east and Hoboken, New Jersey, to the west. The tubes originate at a junction of two PATH lines on the New Jersey shore and cross eastward under the Hudson River. On the Manhattan side, the tubes run mostly underneath Christopher Street and Sixth Avenue, making four intermediate stops before terminating at 33rd Street station. The tubes do not enter Uptown Manhattan; the name reflects their location north of the Downtown Hudson Tubes that connect Jersey City and the World Trade Center. Dewitt Clinton Haskin first attempted to construct the Uptown Hudson Tubes in 1873. Work was delayed by five years by a lawsuit, and was further disrupted by an 1880 accident that killed twenty workers. The project was canceled in 1883 due to a lack of money. A British company attempted to complete the tunnels in 1888, but also ran out of money by 1892, by which point the tunnels were nearly half-finished. In 1901, a company formed by William Gibbs McAdoo resumed work on the tubes, and by 1907, the tunnels were fully bored. The Uptown Hudson Tubes opened to passenger service in 1908 as part of the Hudson & Manhattan Railroad (H&M) and were completed by 1910. After the Uptown Hudson Tubes' opening, the H&M proposed extending them northward to Grand Central Terminal, as well as creating a crosstown spur line that would run under Ninth Street in Manhattan. However, neither extension was ultimately constructed. In the 1930s, parts of the tubes under Sixth Avenue were rebuilt due to the construction of the Independent Subway System (IND)'s Sixth Avenue Line. The Uptown Hudson Tubes contained seven original stations; two stations at 19th and 28th streets were later closed and the 33rd Street terminal was rebuilt. The Port Authority of New York and New Jersey took over the H&M and the tunnels in 1962, rebranding the H&M as part of the PATH system. The Hoboken–33rd Street and Journal Square–33rd Street services operate through the tubes on weekdays, while the Journal Square–33rd Street (via Hoboken) service operates on weekends, nights, and holidays.

Description

Route The Uptown Hudson Tubes travel roughly east–west beneath the Hudson River, connecting Manhattan in the east and Hoboken and Jersey City in the west. On the Manhattan side, the tunnels initially run eastward under Morton Street. At Greenwich Street, the tubes curve sharply north for two blocks, then turn sharply east below Christopher Street. The curve, which follows the streets above it, was made to avoid demolishing basements during construction. The tubes do not enter Upper Manhattan; their name reflects their location north of the Downtown Hudson Tubes that connect Jersey City and the World Trade Center. As well, they were built when today's Midtown Manhattan was considered "uptown" and the true northernmost reaches of the island were not as densely developed. The name "Uptown Hudson Tubes" also applies to the section of the subway under Christopher Street and Sixth Avenue in Manhattan. The first PATH stop in New York is at the Christopher Street station; service continues uptown to the 33rd Street terminal, making intermediate stops at 9th, 14th and 23rd streets. Two stations formerly existed at 19th and 28th streets. The ornately designed stations in Manhattan featured straight platforms, each 370 feet (110 m) long and able to accommodate 8-car consists. The stations underneath Sixth Avenue (14th, 19th, 23rd, and 28th streets, and the original 33rd Street Terminal) contain round columns with scrolls and the station name near the ceilings. The exposed steel rings of the tunnel's structure can be seen at Christopher and 9th streets. On the Jersey City side, the tunnels leave the riverbank approximately parallel to 15th Street and enter a flying junction where trains can turn to Hoboken Terminal to the north or Erie Terminal (now the Newport station) to the south. The junction also allows trains to travel between Hoboken and Newport. Each end of the junction is within one of three double-deck concrete caissons. The Uptown Hudson Tubes enter caisson 1 at the eastern end of the junction, which carries trains to Hoboken or Newport on the upper level and trains from Hoboken or Newport on the lower level. Caisson 2 at the northern end carries trains to and from Hoboken, while caisson 3 at the southern end carries trains to and from Newport.

Worked examples

Example 1 — a first encounter with Uptown Hudson Tubes

Start with the simplest possible case. Write down what Uptown Hudson Tubes claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Uptown Hudson Tubes before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Uptown Hudson Tubes ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Uptown Hudson Tubes

In research
Uptown Hudson Tubes appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Uptown Hudson Tubes in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Uptown Hudson Tubes is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1908 establishments in New Jersey, 1908 establishments in New York City, Crossings of the Hudson River, so understanding it makes those chapters shorter.
In everyday life
Look for Uptown Hudson Tubes outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
