MRT website is very informative! Good work from the developer. It got almost everything that u need; project updates, information about tenders, even reports on special events ex: protest on MRT at Bus Stand Klang last year.

Check it out!

LRT extension and BRT sunway should learn something from here.

I do get a sense that they may very well finish ahead of time?

Ahead of time, I don't know, however tunneling wise, a major milestone will be achieved soon

Very soon, Semantan 1 tunnel boring machine will reach KL Sentral station box



In the northern part of the line, more piers can be seen around Kota Damansara now.

Can't wait for it to finish. Its been long overdue. Hopefully it will ease the jam and the over-reliance on LRT & Monorail in the long run.

Not just it relieves over-reliance on LRT and monorail, ultimately this line will serve areas where there is no rail at all (i.e Damansara).

The beautiful thing about this line is that there might be some extra services which do not serve the whole line. That means frequency can be varied between different parts of the line.

Some MRT stations may have 3 tracks.

Woah... 3 tracks? As in functioning like a commuter or maybe an express line?

No, it is like this.

Case 1: Singapore North-South Line

The whole line is from Jurong East (NS 1) to Marina Bay (NS 27).

In Ang Mo Kio station (NS 16), they have 3 tracks, such as this...



The extra track, they used it to launch more frequent 'Lunch Time Xpress' during lunch hours from Ang Mo Kio to Marina Bay.

Oh... That.... That would be very useful.

Anybody check this vid already? MRT Bukit Bintang station got underground connection to Pavilion, Starhill and Fahrenheit88. Woohooo!

I help you fix this

Construction for the Klang Valley MRT Sungai Buloh-Kajang Line marked an important milestone today, as the first of nine Tunnel Boring Machines (TBM) named Semantan 1, made a breakthrough at the underground KL Sentral Station worksite. This would be the first breakthrough for the MRT Project.

The machine involved is the Earth Pressure Balance TBM, which was launched at the Semantan North Portal on 13 June 2013. The breakthrough follows an excavation of about 1.4km, boring a 6m diameter tunnel for trains that will head north towards Sungai Buloh.

The machine will now undergo maintenance works at the KL Sentral Station worksite before being re-launched for tunnelling through to Pasar Seni worksite next year.

A total of nine TBMs are going to be used to construct the tunnel for the 9.5km underground alignment of the Sungai Buloh-Kajang MRT Line, with 7 underground stations. They comprise of four Earth Pressure Balance TBMs which will be used for the Kenny Hills geological formation, and five Variable Density TBMs for the Kuala Lumpur Limestone geological formation. The underground works contractor is MMC Gamuda KVMRT (T) Sdn Bhd.

Currently, there are seven TBMs which are operational for the MRT Project and are at various stages of tunnelling. They are monitored by personnel who are stationed directly above where the TBMs excavate.

The first TBM was launch by YAB Dato’ Sri Mohd Najib Tun Abdul Razak at the Cochrane Launch Shaft on 30 May 2013, indicating the start of excavation works.

omg. wall pecah to photoshop ke? the tunnel boring machine rosak?

It is not rosak. It means tunneling work has reached to this distance
