Thanks for the updates.

The Spanish media say:
Quote:
Area 1 is delayed by a segment of two to three kilometers of the structure, which was executed by a consortium of Chinese and Arab builders, which has not been received because it is in poor condition.
The solution, agreed in recent days with the SRO client, has been to provide a parallel or hook-up route to complete the works.
Where can it be, near the KAIA airport (Area 2) or near Makkah?
Thanks

I wanna go to Umrah for 10 days.
I'm told it's best if I stay inJwddah and commute TO makkah via train as living costs in Makkah during thelast 10 days of Ramadan are just outrageous

Please advise

Click the link for a recent map of railway lines in Saudi Arabia.



gree line: Line in operation
red line: Line section U/C


Hope this may help understanding the ambitious Saudi Arabian railway infrastructure construction program. Also check out the line cutting through high dunes in the central desert (activate "aerial view")...

Haramain

Talgo train reaches 310km/h on Saudi HS line IRJ.
Quote:
TESTING of Saudi Arabia’s 453km Haramain high-speed line reached a milestone on June 15 when a Talgo 350 train reached 310km/h on the section between King Abdullah Economic City (KAEC) and Medina, exceeding the maximum commercial operating speed of 300km/h for the first time.

In the coming weeks speeds will be incrementally increased to 330km/h (maximum speed +10%) as the train fleet moves towards final approval for passenger operation.

Talgo says dynamic testing is proceeding satisfactorily in extreme environmental conditions, with outside temperatures of up to 50oC and windblown sand.

The trains are equipped with a so-called “desert pack” encompassing more than 30 additional technologies developed specifically for the project. Features include certified thermal resistance of up to 50oC and an auxiliary power supply which is capable of keeping the air-conditioning system operational for more than two hours in the event of an overhead electrification failure.

The trains are also equipped with blowers positioned close to the wheels to clear sand off the track, positive atmospheric pressure, military-grade air filters, reinforced door seals to prevent dust ingress, and polyurethane sheeting on the driving cab windows to reduce wear from blowing sand.

Talgo is supplying 36 of the 215m-long trains (including a royal train) with an option for 20 more. The manufacturer will maintain the fleet for 12 years.

El Talgo Haramain alcanza en pruebas los 330 km/h

Quote:
The Talgo Haramain reaches in tests the 330 km/h.

The Operation Backup Control Center is already running, which controls the traffic of the line

The stretch in which the tests are being conducted is located between the cities of Medina and KAEC. At the end of July, the train will reach the city of Jedahh on the shores of the Red Sea covering 370 kilometers of line, 80 percent of the 449 between Mecca and Medina. Both cities will be united in less than two and a half hours with intermediate stops at Jedaah, King Abdullah Airport and KAEC.

Haramain

Photograph of the transfer of a composition Talgo 350 SRO from Rivabellosa (Álava) to Las Matas (Madrid) where the locomotives will engage and test the train.
Once checked, each car is separated and moved to Barcelona by truck to embark for Jeddah.

Haramain anti-dust protection

According to the spanish engineering consultant INECO, this is what will be put as protection against powdered sand in the most problematic sections of the Haramain HSR:

First there is a retaining wall, then a zone of stabilized material with a bituminous mixture, a zone of controlled uptake of sand and finally ballastless track covered with a waterproof bituminous layer.




The same in another version:

Pretty similar to what you see on the highways in the eastern province.
Many thanks to HiJazzey!

Not only is the AVE trademark, exclusively for Spain (the trademark will be: Haramain), is the order of the stations. The correct order is Makkah-Jeddah-KAIA-KAEC-Madinah
Last City should be Makkah
So the screen will show the correct information if you are in Madinah Station. Train to Makkah with stops at kaec, Kaia, Jeddah and Makkah

They are not issuing that authorization

The problem with sand(-storms) is surely an engineering and operational challenge. However, I think that only 5% or so of the entire line are affected, concentrated on 3 or 4 sections. So it should be possible to closely monitor those crucial parts.

One of such sand threatened sections:
http://www.retrofutur.org/retrofutur...034)&mt=hybrid


However I still wonder how a precise track alignment can be guaranteed despite the significant temperature differences between day and night.

In Italy in order to attenuate extreme heating up of rails under the sun those get sprayed with white color...

In contrast the 2015 opened North-South railway runs through the immense desert of central Saudi Arabia. The line is supposed to be run at 200km/h (though I doubt this) by CAF built diesel trainsets.
In the linked aerial imagery below one can distinguish two rails: In the upper part of the image (dated 2015) one can see the dark and still clear ballast of the trackbed as it should be, in the lower part one can see the trackbed already submerged by sand:
http://www.retrofutur.org/retrofutur...445)&mt=hybrid
(Zoom out to get an idea about the size of this desert...)

It was not an opinion, it is official information of Adif and Renfe.

Another one, and from last week:

You have to put the image to make it look:


He says that after Jeddah (21:30) there is Madinah (22:15), so it is wrong.
He has to put Makkah 22:15

Yes, I know him.

These are the problematic sections:


According to Adif will be dilating devices. This is Type A for Spain, I do not know if it will be a special one.


Basically, with the heat the rail slides on the outside for continuity to alignment.
I do not know how to explain it better in English. Sorry!

Interesting. Are those dilation devices used in plain sections of high speed lines in Spain? Usually those are placed next to the abutments of bridges ("para puentes"), but if I get you right you mean those are also inserted in plain line? There must be many of them if so...

No, only on bridges. In the lines on ballast are used the dilation joints, much simpler.

They will be used in Arabia (Adif said they would be used, but I have not seen photos) because of the great difference in temperature.
In Spain it is very hot (Seville, Cordoba, Malaga) but there is not so much difference between day and night.

I have to go. If you have any more questions I will look again this afternoon.
