1. MRT is different compared to LRT. The economic impact is also different. Judging from Singapore experience.
2. The rail system that we are talking today comes under a unified company and is better managed, integrated as well as regulated. We are also talking about having commercial within rail and creating multi-modal hubs with high focus on feeder buses. All these came only in recent years.
3. Long time ago, our LRT was built to cater to Commonwealth Games and subsequently used mainly by working people going to KL city. However, the traffic and parking condition today is far far more severe than before creating a massive desire to put people onto urban rail.
4. There is also a changing demographics where more and more younger people are working or studying in city or locations near the LRT/MRT. KL has many times more outstation people today too and our foreign tourists have tripled over the last 10 years.
5. Working people today are also more keen on public transport as long as the quality improved and it connects their home to office or shopping malls. People want convenience and saving time, rather than stuck in jams, no-parking situation and a seemingly prefer walking through "air-con" condition. This explained the drastic surge in ridership over the last few years and if the trend continues, our Rail system will have brighter chance to improve.
6. Locations within the current LRT have seen property prices moving upwards. Last time, Kelana Jaya is not worthwhile, but now is a different story.
7. The MRT that we are planning in coming years will be of a high-impact one. Developers believe alot of quality and affordable homes will be built near MRT causing a price hike in the location-specific, partly because those MRT locations have scarcity in land. Also, Prasarana is venturing into integrated property for the first time (they have not done so with LRT so many years).
8. I believe, likewise in Singapore, there'll be some regulatory change whereby entering the City Centre would require car drivers to pay more. Hence forcing more people to get onto the trains. The objective is because the Govt has intention to increase the public transport share by 2020.
Bother, it took Singapore > 30 years, to have superb public transport connection today.
& only last 5 years Singapore started to build extra links non stop.
While I am sad, Malaysia like to build LRT & ktm from initial, and still poor connections 10 years back... Most of the time, I really cannot understand and appreciate the initial planning...
Anyway, MRT will be the KL dream comes true.
