Action note: In: Summary: ABSTRACT: The national government has focus its attention in solving worsening road traffic problems in the metropolis by providing a mass transportation system such as Light Rail Transit. At present, there are three LRT lines that servicing at least 850,000 commuters daily. These three lines composed of Line I- form Baclaran to Monumento, built in 1985 using 100% ballasted track; Line 2- from Santolan to Recto Ave., completed in 2004 using 100% direct fixation track; and Line 3- from North Ave. to Taft Ave. constructed in 2000 utilizing approximately 55% direct fixation and 45% ballasted track. The study aims to compare the conventional ballasted track to direct fixation track. It also applies to determine the advantages and disadvantages of each track support system. The study will also set sight on the introduction of railway standards to our prevailing codes that will guide engineers with regards to international railway practice. A descriptive method of research was used to compare the track support system. Interviews were conducted to those people with extensive experience in the design, construction and maintenance of railway track system. A survey was also conducted to determine which truck support system in advantageous in the long run. The study concludes that for elevated structures, direct fixation is the better choice. On the other hand, at-grade construction will favor ballasted track due to its lower construction cost but after 16 years of operation the difference in construction cost will balance out due to its high maintenance cost. Finally, direct fixation tract is recommended as the better choice between the two track support system due to its economical, structural and practical advantage over ballasted track.
