Pujiang Line

Pujiang Line is a science 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 Pujiang Line rather than just read about it. In short: The Pujiang Line (simplified Chinese: 浦江线; traditional Chinese: 浦江線; pinyin: Pǔjiāng Xiàn) is an automated, driverless, rubber-tired Shanghai Metro line in the town of Pujiang in the Shanghainese district of Minhang. It was originally conceived as phase 3 of Shanghai Metro line 8, but afterwards was constructed as a separate line, connecting with line 8 at its southern terminus, Shendu Highway.

Key takeaways

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

Reference excerpt

The Pujiang Line (simplified Chinese: 浦江线; traditional Chinese: 浦江線; pinyin: Pǔjiāng Xiàn) is an automated, driverless, rubber-tired Shanghai Metro line in the town of Pujiang in the Shanghainese district of Minhang. It was originally conceived as phase 3 of Shanghai Metro line 8, but afterwards was constructed as a separate line, connecting with line 8 at its southern terminus, Shendu Highway. The line opened for passenger trial operations on March 31, 2018. It is the first automated, driverless people mover line in the Shanghai Metro, and has 6 stations with a total length of 6.689 kilometres (4.156 mi). The people mover was expected to carry 73,000 passengers a day. The line is colored gray on system maps. The line is operated by Shanghai Keolis Public Transport Operation & Management Co. Ltd. (Chinese: 上海申凯公共交通运营管理有限公司), a joint venture owned by Keolis and Shanghai Shentong Metro Group for at least five years after opening.

History

Stations

Service routes

Important stations Shendu Highway - Passengers can interchange to line 8.

Future expansion There are no plans to extend the line.

Station name change On June 9, 2013, the Aerospace Museum was renamed Shendu Highway (before Pujiang Line began serving the station).

Headways

Technology

Signalling The entire operation of the new line is remotely controlled from a central dispatch room. Trains operate using the Cityflo 650 communications-based train control (CBTC) from CRRC Puzhen Bombardier Transportation Systems Limited, a joint venture between Bombardier and CRRC Nanjing Puzhen Co., Ltd. The automatic trains had initially six staff members working at each APM station, but the operator hopes to reduce that to one or two.

Rolling Stock

Pujiang Line uses rubber-tyred Bombardier Innovia APM 300 trains. The trains have 4 cars each, totaling 51 metres (167 ft) in length, with capacity for 566 passengers per train. There are large windows at each end of the train allowing passengers to look out the front and rear. The small trains with rubber tires running on concrete tracks allow for turning radii as tight as 22 m (72 ft) to be negotiated, compared to over 300 m (984 ft) for typical metro on steel rails. On 13 January 2017, Bombardier delivered the first out of 44 autonomous people movers to Shanghai.

Worked examples

Example 1 — a first encounter with Pujiang Line

Start with the simplest possible case. Write down what Pujiang Line claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Pujiang Line 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 Pujiang Line 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 Pujiang Line

In research: Pujiang Line appears in science 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 Pujiang Line 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: Pujiang Line is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2018 establishments in Shanghai, People mover systems in China, Pujiang Line, so understanding it makes those chapters shorter.
In everyday life: Look for Pujiang Line 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.

Frequently asked questions

What is Pujiang Line in simple terms?

Why does Pujiang Line matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Pujiang Line?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
