Each coach is also equipped with two units of mounted air conditioners. Each train has its own Public Address System PAS from which a recorded computerized announcement of each station stop emanates. The PAS could transmit music for a relaxing journey.
Designed to be commuter-friendly especially for the mobility-impaired, all elevators in all terminals of the Purple Line are with an engraved Braille, while all station concourses and platform levels are installed with path finding tactiles to guide persons with disabilities, specifically the visually-impaired.
In keeping with the fast-paced computerization and modernization of the world, the Purple Line is the first in the country to use two novel innovations in the mass rail system.
The OCC networks necessary internal and external linkages for an efficient, safe and secured service to commuters. These allow the on-the-spot recording and confirmation of all goings-on in all the stations.
The Supervisory Control and Data Acquisition is responsible for the remote control management of the power supply to the depot and the entire The Building Management System takes care of the Katipunan underground air-conditioned station. The Centralized Paging Information System is the public address system that connects the management to their frontliners and passengers.
The schematic diagram aids the OCC engineers know the problem track areas of the computerized trains which have their own black boxes similar to those of aircraft carriers. With the goal of the national government through the Light Rail Transport Authority to provide the public with an alternative means of transportation, it is believed that Megatren or the Purple Line results in less traffic congestion on the roads, reduction in air pollution, a cleaner environment, considerable savings in travelling time, great economic benefits and a higher quality of life for commuters.
The ease and convenience for large numbers of people to access the stations produce commercial, retail, and office development opportunities that contribute to faster urban renewal. Friend's Email Address. Your Name.

Since a light rail track can carry up to 20, people per hour as compared with 2,, vehicles per hour for one freeway lane, light rail could theoretically deliver significantly more congestion-reduction potential per dollar as incremental freeway lanes in congested urban areas.
For example, in Boston and San Francisco, light rail lines carry 9, and 13, passengers per hour, respectively, in the peak direction during rush hour. Combining highway expansion with LRT construction can save costs by doing both highway improvements and rail construction at the same time.
The project came in under budget and 22 months ahead of schedule. LRT cost efficiency improves dramatically as ridership increases, as can be seen from the numbers above: the same rail line, with similar capital and operating costs, is far more efficient if it is carrying 20, people per hour than if it is carrying The Calgary, Alberta C-Train used many common light rail techniques to keep costs low, including minimizing underground and elevated trackage, sharing transit malls with buses, leasing rights-of-way from freight railroads, and combining LRT construction with freeway expansion.
Its operating cost per passenger was also much lower because of its higher ridership. Search Search for:. Light Rail Transit Light rail or light rail transit LRT is a form of urban rail public transportation that generally has a lower capacity and lower speed than heavy rail and metro systems, but higher capacity and higher speed than traditional street-running tram systems.
Comparison to other rail transit modes With its mix of right-of-way types and train control technologies, LRT offers the widest range of latitude of any rail system in the design, engineering, and operating practices.
Train operation An important factor crucial to LRT is the train operator. The cars have sidewall heaters for passengers. The trains have heavy thermal insulation, too.
Door thresholds are no longer heated, as they have been in older cars. Metro Transit said it has had corrosion problems with older light-rail cars on the Blue Line, so it made sure the undersides of Green Line cars had corrosion-inhibiting paint that also makes for a quieter ride. Metro Transit said the trains underwent more than 1, customizations, large and small, with Minnesota in mind. Hit the brakes The trains have several kinds of braking systems that can be used sequentially.
First, electric motors slow the vehicle by changing operating modes. Second, huge disc brakes slow the trains further. Third, a sand-spraying system kicks in if the wheels begin to slide. Fourth, if necessary, magnetic brakes are activated. Shared or converted railroad alignments, center boulevards, exclusive lanes, and short aerial or underground structures are the usual means of accelerating LRT to improve trip time.
Simple, traditional street operation is effective only when travel volume is sufficient to justify LRT on its productive efficiency rather than its speed. For maximum efficiency, LRT must often closely integrate its service with that of a local bus network, but on long, fast radial lines serving a central business district, integration, although desirable, may not be a necessity. Conditions under which LRT works best range from long, fast, low-density suburban lines to short, slow, high-density inner-city lines.
