1The train that passes through a residential building
With the Daba, Wushan, Wuling, and Dalou Mountains to the north, east and south, most of Chongqing's terrain is made up of hill slopes. That, coupled with the lack of space due to the high building density and a population of around 49 million people, makes working on infrastructure a real challenge for architects and city planners. In 2004, when the Rail Transit No.2 was approved, they only had two choices; to either tear down the whole apartment building to make room for the monorail or clear two floors and make a tunnel so that the train can pass through it. As unconventional as it seems, experts went for the second option, and 13 years later they are still convinced it was the right thing to do. (Source)
2The narrow street that has a train passing through it
This is the case for many in Hanoi. On a busy city street, people live and work alongside the railroad tracks found in the city's Old Quarter, and only move temporarily when the train passes. Shops are shut down, and immediately re-opened just as soon as it brushes past.
3The trains that pass through the world's longest rail tunnel
Goods that until recently were carried on the route by a million vehicles a year are now able to go by train instead. The tunnel has overtaken Japan's 53.9km Seikan rail tunnel as the longest in the world and pushed the 50.5km Chunnel, linking the UK and France, into third place. (Source)
4The train that crosses an airport runway
Tasmania's Wynyard Airport also had a railway crossing on the runway, but moribund rail traffic forced its closure in early 2005. The Gisborne rail route functions between 6:30 in the morning and 8:30 at night.
One of the more appealing aspects of the railway line? When it passes directly on top of the runway, trains have to stop for clearance from the air traffic control to cross and continue down the line. (Source)

Germany. It was opened in 1927 exclusively for rail transport.
Before the causeway was built, the connection to the island was at the mercy of the tides, and in winter, the ice in the Wadden Sea formed an impenetrable barrier—the crossing took about six hours in adverse weather and flow conditions lasted longer. As the seaside resort of Westerland, became increasingly popular, officials started planning the rail causeway. Today, more than 100 trains pass over every day, with 50 of those ferrying cars (there is no road link to Sylt). Each year, the railway ferries more than 450,000 vehicles over the causeway. (Source)
7The Chinese train that plans to run 13,000 miles to the US
The proposed line beginning from China's could go through Siberia, the Bering Strait, Alaska, and Canada before reaching the contiguous U.S. Once the line is put to use, bullet trains can run at 350 km per hour, enabling passengers to travel from China to the US in less than two days. Russia, which is heavily dependent on rail transport like China, is also progressively advocating the idea.
Crossing the Bering Strait in between Russia and Alaska would require about 200 km of undersea tunnel. (Source)
8The trains that pass through Bloomer Cut
In 1862, Indiana State Representative William Holman remarked that the Transcontinental Railroad “could never be constructed on terms applicable to ordinary roads…it is to be constructed through almost impassable mountains, deep ravines, canyons, gorges, and over arid and sandy plains.” Representative Holman identified most of the obstacles that faced the construction of the Transcontinental Railroad, and Bloomer Cut is a stunning, historic example of how those obstacles were overcome. The cut is an engineering marvel and a testament to the strength and determination of the laborers who built it. (Source | Photo)
