Does anyone know how the yellow line will cross the number 7 highway?  The skinny monorail pillars go up to the edge of the motorway (which is elevated here).  How will it span that huge road?  It is seven lanes inbound at that point and 6-7 lanes outbound with no divide between where they can erect a pillar.  There would easily be 2-3 pillars in that space normally, but they can't have any.

Is it going to be a mini suspension bridge?  Or truss?  Just curious to know.

So watching this develop I still have no idea how it will get across.  They have now built support columns either side of the motorway and they are much thicker than the usual supports.  But it is 50/55 metre span between them so I don't see how it can be done in one go, but they obviously will do it somehow (normally the supports seem to be no more than 20 metres apart).  Anyone know?

Interestingly also as soon as it has crossed the motorway it dives down to go underneath the ARL - it also splits in two to go around an ARL support column which is right in the way - before climbing immediately back up into Pattanakarn station.  Seems quite steep too.  I wonder why they didn't go over the ARL as it looks like a lot of extra work to go under.

The Airport Link easily span over 8 lanes of traffic around Makkasan. Maybe something Similar.

But, I agree it is a long span over 12 lanes of traffic.

Not sure.  This is 13 lanes and a different kind of construction as the monorail beams are single pieces and pretty thin.

Maybe steel girders. See page 150-151.

Nice find, thanks!  I would say definitely a steel girder then as they say maximum length is 60m and I reckon it is 50 metres there.  Also the pillars on either side of the motorway are thick just like these in the picture.  So I reckon that's it!

Inner geek satisfied.  Still would like to know the reasoning for diving down underneath the ARL then straight back up.  Just seems logical (and less engineering) to go over it but I am sure there is a very good reason.

In a distant future a high speed rail line will connect Don Mueang, Swampy and Utapao. I imagine it will run partially parallel to the ARL along this section and maybe the high speed rail line is to tall for the moon rail to pass above it.

Actually, the Eastern HSR line will take over the ARL. The ARL will need to be shut down at some point once the ext to DMK is done first in order to do install a new signalling system and finally replace the substandard chinese built rail.

 

However, as mentioned in the previous page the SRT Light Red Line is still planned to be extended to Hua Mark so that will require a new viaduct along the ARL.

I was looking for some renders but could not find them. However, you can see in the route video around the 2 min mark the configuration of the line when it passes the Chonburi Motorway. Larger cross support beams will be built on the south side of the motorway. 

 

The reason why the line passes under the ARL is so that the station can be built at a reasonable height as otherwise the station would have to be much higher and the interchange to the ARL would be more cumbersome to construct. It also allows air space for the future SRT Light Red viaduct to be more easily built.

6 October 2017

I mentioned in the previous update that I would post a summary of new rolling stock orders;

 

A) BEM Blue Line (MRT) -

BEM finally placed an order with Siemens a few weeks ago for new rolling stock!!! Originally, they were going to order more stock in 2008 but had to defer due to debt restructuring issues so it has been a long wait! BEM has ordered 35 new 3 car sets which will be delivered in 3 stages ; 


1) 3 sets in late 2018,
2) 15 sets in early 2019,
3) 17 sets in late 2019.
(Note: BEM should be moving to 4 or 5 cars sets by now as expected pax after the extension are 750k-800k rising to 1m by 2022)

 

B) BTSC Dark Green (Suk) line  (BTS) -

1) The BTSC has ordered for 22 new 4 car sets from Siemens in May 2016 for the when the Samut Prakhan extension. These are being built in Turkey with expected deliveries in late 2018 & early 2019.

2) At the same time, the BTSC ordered 24 more 4 car sets of CRRC (Chinese) for the North ext to KuKot/Lam Lukka rd. These should be delivered in late 2018.

(Note: 4 sets will be kept for reserve/repairs etc)

 

C) BSR Pink and Yellow line (MRT) monorail orders -

1) Pink Line: BSR has ordered 42 Bombardier Innovia Monorail 300 sets  (4 cars)

2) Yellow Line: BSR has ordered 30 sets (4 cars) of the same model.

 

D) SRT Dark and Light Red suburban lines -

Hitachi has the contract to supply rolling stock by 2020. However, the exact number of sets is unclear.

 

E) SRTET Airport Line (ARL) -

1) The order for 7 new 5 car sets is still pending. However, the SRT has promised to place it by the end of the year.

 

Summary:

That's a total of 81 heavy rail sets (3 & 4 cars) and 72 monorail sets (4 cars) on order!

 

BSR MRT Pink line and MRT Yellow line monorail orders

The first sets for both lines have been assembled and shipped on 4 Sept to Thailand. They should arrive by the end of the month.

All other sets will be progressively delivered during next year with final deliveries expected by 1st quarter of 2022.

Thanks LG, I was hoping you would pop up with information.  Very interesting and makes sense, thanks for sharing.  I had been wondering about that for a long time.

They actually look really cool, and much bigger / wider than I was expecting.

Silom line S4 construction update - Suksa Witthaya

The construction of one of the 2 original missing stations (S4 & N6) is now 50% complete with an expected opening by March 2021.

What was the reason to build Suksa Witthaya station?
