The main question to be asked is why KTMB making this proposal and not Prasarana nor RapidKL? After all, Prasarana and RapidKL were given the task to integrate the public transport networks in the Federal Territory of Kuala Lumpur and the Inner Klang Valley while KTM Komuter were expected to move people in and out of KL.

There are proposals to build a KL-Kepong-PJ-Seri Petaling LRT ring line, by extending the Ampang line from Seri Petaling through Petaling Jaya and from Sentul to Sg Buloh. These lines would meet in the Damansara area.

While the proposed KTM Outer Ring Rail line would serve a wider area than the KL-Kepong-PJ-Seri Petaling LRT ring line, there still will be areas where KTM and RapidKL will end up as direct competitors.
