LRTA 1100 class


The LRTA 1100 class is a high-floor LRV of the Light Rail Transit Authority in Manila, Philippines, which began operation in 1999.

History

To enhance the transportation capacity of Line 1, between 1997 and 1998, 28 cars are produced by Hyundai Precision as its first manufactured light rail vehicle. The capacity extension project was due to traffic congestion and air pollution, which in turn led to an increased demand for public transport in Metro Manila by the LRT Line 1.
The handover ceremony and test-run of the 1100 series LRV was done with former President Joseph Estrada and former Vice-President Gloria Macapagal Arroyo.

Design

Structure

Similar to the 1000 class, the 1100 class have cheatlines of blue and yellow that run through its sides.

Interior

The trains have longitudinal seating. A wheelchair provision is present near the articulated portion of the intermediate cars.

Drive unit

Traction control system is IGBT-VVVF type. The traction motor is a three-phase induction motor.
The original VVVF controller is supplied by ADtranz, while the new VVVF controller done during the refurbishment period is supplied by Voith.

Operations

The 1100 class entered service in 1999, which raised the line's capacity by half. After 2001, many vehicles left the service owing to problems in operations and maintenance. Although spare parts had been substantially given in 2004, 14 cars remained out-of-service due to the lack thereof as of 2013, with two cars inoperable after a collision.
2 out of the 7 sets remained in service. Rehabilitation was initiated by LRMC in 2018, which aimed to restore the inactive fleet into serviceable conditions and increase the capacity of Line 1. LRMC and Voith signed an agreement to refurbish the said fleet which includes the control devices, traction systems, and automatic diagnostic displays of main circuits. The refurbishment was carried out between 2019 and 2020 and 6 out of 7 sets returned to operation with an extended vehicle life.
In addition, these trainsets are commonly used as "skip trains" or trains meant to target a particular station due to extremely high volume of passengers, especially at rush hours.
