This seems very common in the middle east. I haven't seen it anywhere else in the world with the exception of certain long distance / express suburban trains.

Riyadh-Metro Map Anomalies

On this website:
http://tunneltalk.com/Saudi-Arabia-0...tro-Line-1.php
it quotes "...construction of Riyadh Metro Lines 1 and 2 (Blue and Green Lines)..." on the map accompanying that it shows the Line 2 (Green) as the one running East-West in the middle segment of Riyadh. But on the more recent maps Line 2 is shown as being coloured "Red", and with the "Green" colour allocated to the Line 5 running North-South next to the Riyadh Air Base. It also shows the Southern-most East-West Line 3 as being the "Red" one. This map is still being reproduced in many blogs and news-sites.

The story allocating the line contracts to the FAST Group, as here:
http://tunneltalk.com/Saudi-Arabia-2...-contracts.php
reinforces the colour schemes mentioned above.

However, the map showing the first seven launch shaft sites for some of the TBMs located here:
http://www.skyscrapercity.com/showth...632738&page=10 Post #190
shows Line 5 as being the "Green" one, and Line 3 as being "Orange"

The map shown at:
http://www.skyscrapercity.com/showth...632738&page=10 Post #197
also shows the latter colour scheme.

Which is correct? Which colours are allocated to which Line numbers, please?

Also the maps need to show which sections of line are underground, and which sections are elevated on viaduct?

There is actually an official website where numbers of lines are shown. Map posted in 2013 was published at the time when metro construction was in early stages, so more recent maps are correct.

At the moment there are no maps, which shows which sections are underground or elevated

First Alstom metro cars for Riyadh under construction
16 Nov 2015







SAUDI ARABIA: Production of the first of 69 two-car Metropolis trainsets for Riyadh metro lines 4, 5 and 6 has begun at Alstom’s Katowice plant in Poland.

Metro project promoter Arriyadh Development Authority expects to unveil a full-size mock-up of a trainset in Riyadh shortly, and is scheduled to take delivery of the first three completed Alstom trainsets in 2017.

The two-car driverless Alstom Metropolis trainsets sets will be 36 m long and 2 710 mm wide, with all axles powered to cope with gradients of up to 6%. The interiors will have standard, first and family classes, with LED lighting, air-conditioning and an ‘advanced’ passenger information system

[NEWS]24% of Riyadh Metro work done

Source Link

Quote:


RIYADH: The Arriyadh Development Authority (ADA) celebrated on Monday morning the arrival of the giant machine called “Jazlah” which is used for digging tunnels for the Riyadh Metro project
“We celebrate today the arrival of the drilling machine Jazlah at one of the train stations in Riyadh in the presence of the Italian premier,” said Ibrahim bin Mohammed Sultan, member of the ADA planning board. Jazlah is the fifth of seven machines needed for the project. Among the celebrants was Italian Prime Minister Matteo Renzi, who is currently in Saudi Arabia. He was welcomed by Sultan and other ADA officials and leaders of global companies.
“We haven’t gotten to the advance stages of implementing the Riyadh Metro project but we thank Custodian of the Two Mosques King Salman and Riyadh Gov. Prince Faisal bin Bandar for their support,” he said. He added that “it’s a giant project that affects all aspects of life in the city, which operates the program timetable.”
He noted that some 24 percent of the project has so far been achieved, adding that some 800 Saudi engineers are involved in the project.
The station is on the orange line of the King Abdulaziz Project for Public Transportation. It goes all the way to the Madinah-Prince Saad Abdulrahman Street in the Saudi capital.
Those present on the occasion watched the machine begin work at the terminal wall located at depth of 25 meters underground.
The machine will bore the tunnel for the orange line route from south of Prince Faisal bin Fahd Stadium in the Malaz district.
After penetrating the terminal wall, Jazlah continued its way down, digging a tunnel with a length of 6.5 km on the orange line which is 40.7 km long.

Hi guys,

I have enjoyed going through this thread. I have left Riyadh before the construction of the Metro started but I keep following thanks to this forum.

May I please ask if anyone of you works on this project? I'm trying to contact people in charge of the TBM to see how they deal with the wear troubles. Is the soil very hard? How do you protect the cutting disks?

Thank you!

I don't work on the project, but I have visited one of the TBMs. I didn't understand "wear troubles"?!

For the soil, actually as you know, there're more than one TBM in the project. and I will remind you, if you don't really know, Riyadh city is very large. So, the soil will be different form one particular place to another. I see the most easy soil is the one on the middle of Riyadh (San'ah) on the green line (King Abdullaziz Road). They have reached more than 43M/day which is near to the highest number globally (which is ~48-49M/day). And also, in the place of one of the TBMs that I have visited, they ware telling me that they are facing a problem with the water inside the soil and the earth itself! The machine which I visited is on the 3rd line (the orange line). And the name of it is (Jazlah).

And I will answer you from my point of knowledge (not like engineers ), they use a lot of water to protect the machines.



And guess what? The first and the fastest machine (Sana'ah) is going to finish (by the order of Allah) on March of 2016, which is before the scheduled date by 8 months!

Thanks for the answer iKhaledM.

What I mean by "wear troubles" is that basically, you dig the soil so the machinery parts will eventually get worn out as they are in contact with sand/rocks/soil....If the soil is very hard to dig, it can become costly to dig and it might get more time as you always have to stop the machine to repair/replace parts.
Solutions exist to increase the lifespan of the machinery parts and I was wondering if the people in charge of the TBMs were using it or if they didn't need it.

The only way for you not to need it is if the soil is not hard at all or if you have plenty of money to spend
