I agree with the writer of the letter of LRT breakdown - rethinking the automated LRT . We certainly do not need another LRT extension to Subang Jaya with all its inherent problems. Let us compare both LRT technologies being used in Kuala Lumpur.
The Putra LRT uses a unique linear induction magnetic technology that is a proprietary of Bombardier of Canada. Whereas, the technology used in the Star line is more 'open' standard and can be supplied by Siemens or Hitachi.
There has not been any major breakdown in the Star line since its inception. There were some minor interruptions but they were solved within an hour or so.
In terms of comfort level, I find that the Star line provides more comfortable andspacious seating as compared to the 'cramped' feeling of the Putra LRT coaches. The Star LRT also reminds me of Singapore MRT's seating and standing arrangements.
Therefore, I do suggest that the government rethink their strategy to extend the Putra LRT line to Subang Jaya. A better alternative solution would be to extend the Star Sri Petaling Line to Subang Jaya.
I would suggest the following extension route for the Star LRT line:
Sri Petaling -Bandar/Taman Kinrara - Puchong Jaya - Summit/USJ SS 15/KTM station - Sunway - Kelana Jaya
Kelana Jaya would serve as an interchange for the Star and Putra LRT lines.
