Question: The Yiwu - Madrid Railway line is one of the routes that are rail links between what two land masses?

Context paragraphs:
Yiwu–Madrid railway line: The Yiwu - Madrid Railway line is a railway route taken by container trains from the Chinese city of Yiwu to the Spanish city of Madrid, a distance of roughly 10,000 kilometres (about 6,111 miles ), 741 kilometres more than the Trans-Siberian Railway, the longest until now.  It is one of several routes used by long distance freight trains on the "New Eurasian Land Bridge".  (Other city pairs connected by regular freight trains running between China and Europe include e.g. Lianyungang and Rotterdam, or Yiwu and Warsaw; as of 2016, at least 12 Chinese cities and 9 European ones were connected by similar trains.)

Dokis First Nation: Dokis 9 is a First Nations reserve and community in the Canadian province of Ontario, assigned to the Dokis First Nation.  The reserve is located approximately 16 kilometers southwest of central southern Lake Nipissing along the French River.  It is divided into two large parts consisting of a north island, Okikendawt, and a large southern peninsula.  The two land masses, which are nestled within the flows of the French river, covers 154.36 square kilometers.  The French River watershed in Northern Ontario was created more than ten thousand years ago when the last ice-age receded and left a maze of rivers and small lakes.  The main settlement is found on Okikendawt island (meaning island of buckets or island of pails) which can be accessed by a gravel road which connects with Highway 64.  The Land is occupied by the Dokis and its cousin tribe, the Restoule‘s.  The land is well known for its hunting, fishing, fur trades, and timber.

High-speed rail in Europe: High-speed rail is emerging in Europe as an increasingly popular and efficient means of transport.  The first high-speed rail lines in Europe, built in the 1980s and 1990s, improved travel times on intra-national corridors.  Since then, several countries have built extensive high-speed networks, and there are now several cross-border high-speed rail links.  Railway operators frequently run international services, and tracks are continuously being built and upgraded to international standards on the emerging European high-speed rail network.  In 2007, a consortium of European railway operators, Railteam, emerged to co-ordinate and boost cross-border high-speed rail travel.  Developing a Trans-European high-speed rail network is a stated goal of the European Union, and most cross-border railway lines receive EU funding.  Several countries — France, Spain, Italy, Germany, Austria, Sweden, Belgium, the Netherlands, Russia and the United Kingdom — are connected to a cross-border high-speed railway network.  More are expected to be connected in the coming years as Europe invests heavily in tunnels, bridges and other infrastructure and development projects across the continent, many of which are under construction now.  Alstom was the first manufacturer to design and deliver a high speed train or HS-Train, which ended up in service with TGV in France.  Currently, there are a number of high-level manufacturers designing and building HSR in Europe, with criss-crossed alliances and partnerships, including Canadian company Bombardier, Alstom itself, the Spanish Talgo and the German Siemens.

Mackinaw City, Michigan: Mackinaw City is a village in Emmet and Cheboygan counties in the U.S. state of Michigan.  The population was 806 at the 2010 census; the population surges during the summer tourist season, including an influx of tourists and seasonal workers who serve in the shops, hotels and other recreational facilities there and in the surrounding region.  Mackinaw City is at the northern tip (headland) of the Michigan's Lower Peninsula along the southern shore of the Straits of Mackinac.  Across the straits lies the state's Upper Peninsula.  These two land masses are physically connected by the Mackinac Bridge, which runs from Mackinaw City north to St. Ignace.  Mackinaw City is also the primary base for ferry service to Mackinac Island, located to the northeast in the straits.

History of rail transport in Pakistan: The history of rail transport in Pakistan covers the period beginning in 1858 during the British Raj, when several railway companies began laying track and operating in what is today Pakistan, and ending during the present-day nationalised company under the name of "Pakistan Railways" (initially known as "Western Railways").  The railway system in Pakistan was originally built as a patchwork of local rail links operated by small private railway companies.  These included the Scinde Railway, Punjab Railway, Delhi Railway and Indus Steam Flotilla companies.  In 1870, these 4 companies were amalgamated into the Scinde, Punjab & Delhi Railway company.  Shortly thereafter, several other railways lines were built including the Indus Valley State Railway, Punjab Northern State Railway, Sind–Sagar Railway, Sind–Pishin State Railway, Trans–Baluchistan Railway and Kandahar State Railway.  These 6 companies along with the Scinde, Punjab & Delhi Railway company merged together to form the North Western State Railway in 1880.  In 1947, when Pakistan achieved its independence from Great Britain, the North Western Railway renamed  Western Railways and the railway system underwent reorganisation, some of which proved controversial.  From the start of 1948, usage of railways increased and the network became profitable.  Declining passenger numbers and financial losses in the late 1980s to early 1990s prompted the closure of many branch lines and small stations.  The 1990s saw severe cuts in rail subsidies and mismanagement within the company.  Due to falling passenger numbers, rail subsidies from the government are necessary to keep the railways financially viable.

Strait: A strait is a naturally formed, narrow, typically navigable waterway that connects two larger bodies of water.  Most commonly it is a channel of water that lies between two land masses.  Some straits are not navigable, for example because they are too shallow, or because of an unnavigable reef or archipelago.

Yiwu-London railway line: The Yiwu – London Railway Line is a freight railway route from Yiwu, China, to London, United Kingdom, covering a distance of roughly 12,000 km (7,456 miles).  This makes it the longest railway freight route in the world.  It is one of several long distance freight railway routes from China to Europe on the “New Eurasian Land Bridge” and part of establishing a modern-day Silk Road.  The route was opened on the 1st of January 2017, making London the 15th European city to have a railway route connection with China, and takes 18 days to complete (other European cities with China-Europe railway routes include Hamburg, Madrid, Rotterdam, Warsaw, etc.).

New Eurasian Land Bridge: The New Eurasian Land Bridge, also called the Second or New Eurasian Continental Bridge, is the southern branch of the Eurasian Land Bridge rail links running through the People's Republic of China.  The Eurasian Land Bridge is the overland rail link between East Asia and Europe.

Kanniyakumari District Railway: The Madras government of the South Indian Railway wanted to extend their rail links into Travancore (Thiruvithamkoor) for commercial interests of both the states, during 1873.  The Chief Engineer of Travancore, Mr. Barton, suggested a proposal to link Travancore by a railway line drawn from Kovilpatti of Madras state to Trivandrum (since renamed Thiruvananthapuram) through Shencottah in the Chittar mountain area, and from Trivandrum to Quilon (since renamed Kollam), the commercial centre of Kerala.  Although the "South Indian Railway Company were inclined to make a survey of the southern route via the Aramboly pass to Trivandrum, --- the balance of opinion was in favour of the Northern route,[so] they obtained permission to survey that as well" The Dewan of Travancore Mr. Ramiengar "suggested that a line from Kovilpatti to Quilon through Shencottah would be the one most advantageous. "About the close of 1881 the Consulting Engineer for Railways ordered for a trial survey of the line from Tirunelveli to Trvandrum via Shenkottai, Aryankavu and Quilon.  Immediately the Chief Engineer of S.I.R took up the survey of, both the Southern and Northern routes to Trivandrum.  In 1882, he submitted the report wherein he discussed the merits and demerits of both the routes.  He held that the southern route would be cheaper and more beneficial than the northern one.  But Dewan Ramiengar was strongly in favour of the northern route which would better promote its commercial interests of the country since Trivandrum was no more important commercially than Quilon.  So the northern route was approved by the S.I.R. authorities and work started to link Tirunelveli Quilon via Tenkasi, Shencottah and Aryankavu.  In 1913, the Secretary of State for India sanctioned the extension of railway line from Quilon to Trivandrum beach (present Pettai Station) and it was opened for traffic on 1 January 1918.  In 1926 the extension of this line from Trivandrum Beach to the heart of the city, that is Thampanoor (the present-day Thiruvananthapuram Central), was completed in 1931.  Hence the rail link ended at Trivandrum.  At that point, when the work of extension of the railway line from Quilon to Trivandrum was taken up, there were no proposal or plan to extend it to Nagercoil.

Manahawkin Bay Bridge: The Dorland J. Henderson Memorial Bridge, familiarly known as the Manahawkin Bay Bridge or (while technically inaccurate) The Causeway, is a steel girder bridge that spans Manahawkin Bay, carrying traffic along Route 72 between Long Beach Island (LBI) and the Manahawkin section of Stafford Township, in Ocean County, New Jersey.  The bridge starts at Manahawkin and ends at Ship Bottom on Long Beach Island.  The bridge spans five land masses: the mainland, Long Beach Island, and three intermediate land masses, of which two are small and one is rather large.
