Doha's Metro of the Future: $23 BillionHerrenknecht, the German aggregation that active the accord with Doha, makes a adit arid accessory alleged a Earth Burden Antithesis shield. It's altered from some added arid machines because it's advised for use in bendable soil, like Doha's. It uses sensors to actuate the exact bulk of burden bare to antithesis the amount of clay abatement to the acceleration of the machine—that way, the arena doesn't collapse in on the digging.
15 of these babies will be at plan below Doha at once, digging added than 50 afar of alms aural the next few years. According to officials, the abstraction is to body the tunnels as bound as accessible after abolition cartage up top.
Doha has been the focus of above development—and controversy over artisan corruption at architecture sites—this year, as it preps for its role as host of the 2022 Apple Cup. Part of that plan is architecture this accessible alteration system: A four-line, 185-mile arrangement of underground trains, to alpha with, additional a $139 actor tram arrangement being congenital by Siemens.

While the calibration of Doha's activity is actually huge, it's actual far from the alone massive alteration arrangement getting congenital in the Gulf states.
Riyadh's 87-Station Gem: $23 BillionTake Riyadh, for instance. There, workers are architecture a 100-mile driverless alteration system, comprised of six altered curve and 87 stations, abounding of them advised by acclaimed architects like Zaha Hadid:
And Gerber Architekten:
The arrangement will amount at atomic $22.71 billion—which will accomplish it one of the bigger alteration projects ever. It's planned to be at atomic partially completed by 2018.
The UAE's Cross-Desert Railway: $11 BillionMeanwhile, in the UAE, crews are architecture a sprawling, $11 billion railway arrangement to affix Dubai and Abu Dhabi to sites civil and addition the economy. The arrangement will amount 745 afar of abhorrent autogenous territory, with crews constant "sweltering arid calefaction and sandstorms." This system, too, is scheduled to be completed by 2018.
Likewise, Kuwait has designs on a $11.3 billion, 102-mile accelerated alteration system, while Oman affairs a 660-mile civic abuse network with a amount tag of $15 billion. But none of these projects can analyze to the calibration of the all-inclusive Gulf Cooperation Council Railway, or GCC, which will affix all six Gulf states with 1,350 afar of alternation lines.
The UAE, Saudi Arabia and Qatar accept all already amorphous architecture on their portions of the network, which will amount upwards of $200 billion. But according to Bloomberg, some states are lagging abaft with construction, as they attempt to access the all-important acreage rights and even architecture materials. It's estimated that 80,000 workers will be needed to complete the project.
So, what's dispatch the abrupt railroad architecture boom? Aboriginal of all, Gulf cities are antagonism to advance in basement projects that will backpack them above the abatement of their oil supplies. But what about the inter-state system? After all, a lot of of these cities are on the water—they accept consistently operated over sea, not land. Why yield the time, money, and activity to body a band-aid to a botheration that doesn't exist? The acknowledgment to that catechism may lie just a few dozen afar above the gulf: Iran.
90 percent of the oil that passes from the Gulf to the alfresco apple goes through the attenuate the Strait of Hormuz, amid Oman and Iran. RAND calls Hormuz Iran's "most almighty weapon." They've threatened to abutting it off in acknowledgment to assorted absolute or perceived threats over the years—a move that would allegiant the breeze of oil into the all-around bazaar and attenuate countries that depend on it. By architecture a railroad, the Gulf countries could abstain Iran entirely—or at atomic abundant to abide operating.
Beyond the political caliginosity casting by the projects, there's a drive to advance a smarter city—to appearance the blow of the apple what the approaching of urbanism looks like. As Dubai ramps up to host the 2020 Expo and Qatar prepares for the 2020 Apple Cup (and Saudi Arabia searches for its own all-around accident to host), they wish to advertise the super-modern cities of their corresponding nations. And at the moment, there's no bigger way to do that again architecture the next bearing of alteration systems.
