KAFD monorail

Hi there!

As promised, here's a complete walkthrough on Bombardier's first Riyadh-bound Innovia Monorail 300 Train with los of pictures. Anything concerning design and tech specs... well, I probably won't have the answer, but feel free to ask anyhow, i'll try my very best.

Her we go:


Sitting on piece of concrete beamway that was temporarily installed just for the fair: pretty majestic.


She is a beauty...


The Riyadh layout is the shortest possible configuration of the train, two sections, 26 metres long together. Maximum is eight sections, which would make the train roughly 100 metres long. Sao Paulo will have seven-car trains.


Nice detail in the design of the bottom 'skirt':


Although there were roughly 50 other metros, trams, locos and high speed trains on display, the Innovia proved to be one of the most popular exhibits. Guess why.


A proud logo: yes, that is the Riyadh version.


And yes, that is metallic effect paint!


Boarding:


Come on inside:


Front Seat: This will be the kid's favourite spot. And all the Railfans', too!


The interior is very spaceous. No surprise at an overall width of 3.14 metres!


Same seating arrangement as in the Sao Paulo trains:


However, the interior elements are of a somewhat higher quality. See for example the seats, which are upholstered with a vinyl cover, whereas the SP seats, to my knowledge, are solid plastic.


'Emty tube' design: no structural element or technical components are protruding into the passenger compartment. So a change in seating plan or general passenger layout is possible anytime in the future.


Detail of the tinted glass framing the doorways:


One of the doors from the inside. Each car has two on each side, making a total of eight per train. I can't read arabic... must say something like 'welcome to the Innovoa 300...'


The inter-car passageway is only about one-third of the overall car width. This is due the Innovia, unlike other (japanese) monorails, being extremely low-floor. The Interior Floor is just 45 centimetres over the top of the running surface, yielding a lower centre of gravity, thus a shorter bottom skirt, thus a reduced overall height, thus a reduced net weight, thus thus a better net/load ratio (almost 1:1 !!!), lower energy consumption and less costs in material.
The load wheels (there's two of them on a single axle), along with the entire drive and gears are hidden under the slanted cover, just where the two gray seats are. The passageway allows free movement between cars right next to the drive.


Although the passageway is not super-wide, it has a fully flat floor and offers enough space for free movement of passengers.


This is the entire drive, including motor and gearbox, it's that tiny! At the front, on the silver parts, the brake disc attaches...


... whereas on the other side one can see the mount for the (rubber tired) load wheels.


Again, the entire drive is amazingly compact! And the motor is only the smallest part of it. from left to right: drive wheel axle attachment, gearbox (the big black box on the left houses the planetary gears, motor axis and drive axle are perfectly in line, making the entire setup even smaller!), then permanent magnet motor (the flat thing slightly to the right) and finally the mount for the disc brake.


The Passageway seen from the outside. Here under the covers sit two of the four drive units of the train. The front and the rear axle (under the 'noes') are also powered in the same fashion.


The driver's console open: this will only be used in yard operation or in an emergency situation. In normal operation, the lid will remain closed and the train be operated fully automatic without staff onboard.


Driver's view. Pretty rudimental console: a monitor for cctv, a headset for communication with operation control, a basic control panel with speedometer and buttons for doors open/close left/right, emergency power cut and a throttle drive/brake lever. That's it.


That's the way it will look during daily operation. Pretty boring. And: why is the windshield so far away...? What's under the covers??

The answer is: not really much! lot of air... But here comes the killer: the next generation train will have seats there. A full set of four seats in a row just like next to the inter-car-passageway, but facing forward. Now, that's gonna make me scream 'shotgun'!


A quick glance 'under the skirt':
Her you see, from top to bottom:
- Guidewheel (rubber tired) for lateral guidance along the concrete beam (left), together with emergency 'fall back' wheel for cases of a flat tire
- pick up shoe (2x) for the 750V DC current, one for pick-up, one for return 'neutral' current. Remember, the 'rail' of the innovia is made of concrete, so you cannot return current through the track as is done by metros. So, instead of one 'third rail', you have to have two 'second rails'
- support wheel, again with emergency backup. This one does not guide the train, but acts against axial torque on the guidway. Simply speaking: it makes the train stay upright on its beam.
One dirve Axle with two drive wheels, four guide wheel and two support wheels are mounted together on one bogie (-frame). Each car body rests on two bogies via air springs. The air springs can be seen (well not really, as the picture is to dark, but they're there ) to the right behind the guide wheel. More to the front, still on the right, there is an an hydraulic shock absorber, also part of the suspension system.


Difficult to photograph, but worth a try: this is a shot in between the top of the running surface and the underside of the train. Very narrow gap! The big black thing on top is a kind of a bumper. It sits directly behind the nose of the train and is attached to the carbody frame with hydraulic dampers. These will absorb energy in case of a crash.
the little thing with the yellow cables seem to be a horn...? Has anyone ever heard an Innovia honking???
And, most interestingly, on the far side, you can see the front load wheels which run on the top surface of the guideway beam and carry the weight of the train. Always two wheels on one axle. Again, these are also powered.


And last but not least: a big thanks to Peter Timan of Bombardier, chief engineer and 'daddy' of the Innovia monorail project, who told me nearly everything I wrote in this article - and much much more. It's always nice to see that great projects are always powered by people, who are compassionate about their work and really have fun putting their ideas into reality. It really showed on Peter's face when talking about his Team and the 'product'!

This project will be a really big for Saudi customs. Firstly will women be able to ride it? would they have a different section or a family section?

Also will Saudis themselves ride it or only expats? will the expats be treated fairly in seating's? for example if the train is full, would a expat (****,indian) give up the seat for a saudi?

^ these are all important questions that need answers

Question 1 on the first two pages.
Question 2 is A bit ridiculous (thus a bit self-explainatory)

It would be perfect, if I see monorail connections with future metro lines. All I found is monorail map on Bombardier website:

Yes, the monorail would be linked to future metro station at the KAFD.

Wow, Riyadh is surely getting what it deserves.
The monorail prototype was launched in Innotrans 2014 by Bombardier, and got great response by the spectators. I am waitng for the trial runs, which might take place in late 2017 on small stretches. By the way, are Siemens,Bombardier and Alstom seriously manufacturing railsets for different lines, or they form a consortium? Never heard of such a bidding before.
Anyway, I have only three words to say, ''Cheers Riyadh Metro''!

Wish some visionaries like yours could dream for Indian cities as well.........
