LRTA 1000 class
The LRTA 1000 class is the first-generation class of high-floor light rail vehicles (LRV) currently operated by the Light Rail Manila Corporation. It first entered service under the Light Rail Transit Authority in 1984. Purchase. The construction of the original section of the LRT Line 1 was funded by a ₱300 million soft and interest-free loan from the Belgian Government. Additional funding for the project was later sourced from a ₱700 million loan provided by the consortium of ACEC (Ateliers de Constructions Electriques de Charleroi), BN (Constructions Ferroviaires et Metalliques, formerly Brugeoise  et Nivelles), TEI (Tractionnel Engineering International), and TC (Transurb Consult). The trains were included in the second loan package, along with the power systems, signaling, and telecommunications. The trains were manufactured by BN (now Bombardier Transportation Belgium S.A.), while the electrical equipment supplied were from ACEC. A total of 64 trains were built between 1982 and 1983. Design. The LRV design is an 8-axle rigid body consisting of three articulated cars. It is the only 8-axle light rail vehicle in the entire rolling stock of the LRT Line 1, as subsequent trains since 1999 will be built to  the 6-axle design of the LRV. Car body. The LRV is made of BI sheet. Each car has a length of , a width of , and a height of . The 1000 class currently sports a white body livery with blue and yellow cheatlines. Prior to the first refurbishment, the 1000 class wore an orange and cream-white livery under the "Metrorail" branding, and notably had "mushroom-cap" roof-mounted ventilation. Prior to the 2003 refurbishment, each light rail vehicle had 12 roof-mounted forced ventilation units. A refurbished light rail vehicle has five roof-mounted air-conditioning units. Interior. Each  LRV has five door swing plug-type doors per side. Each train car has a capacity of 81 seated passengers and 293 standing passengers, carrying a total of 374 passengers. Seats are colored blue and are longitudinal-type. Mechanical. The bogies are of inside frame type. Each LRV has four bogies consisting of two motorized bogies at the ends of the LRV and two trailer bogies under the articulations. The primary suspension is a conical rubber, while the secondary suspension is a coil spring. Semi-permanent couplers are present at the ends of the non-cab section (section B) of  the light rail vehicles. Electrical. A thyristor chopper traction control system is installed in the trains, and the traction motors consist of direct current (DC) straight-wound motors. Ateliers de Constructions Electriques de Charleroi (ACEC) manufactured the electrical and traction equipment for the trains. The transmission is a right-angle link drive transmitted via gears and two elastic couplings. Braking system. Dynamic brakes are used as a service brake. There are two disc brakes per trailer bogies acting as a service brake and two disc brakes per motor bogies used as an emergency and substitution brake. Each bogie has two  electromagnetic track brakes for use in case of emergency. Operations. The trains originally ran on a two-car configuration. In 1999, it was converted into a three-car configuration when LRTA refurbished the trains and purchased seven four-car trains from Hyundai Precision. However, not all of the train cars are capable to be coupled to form three-car sets. Refurbishments. First refurbishment (1999–2001; 2003–2008). In the early 1990s, the line faced problems due to poor maintenance and overcrowding. In addition, the forced ventilation units could no longer cool the trains properly. From 1999 to 2001, 32 LRVs underwent refurbishment , carried out by the Belgian consortium of BN (Bombardier Transportation Belgium S.A.), ACEC Transport SA, Transurb Consult, and Tractebel. Generally, this involved the repair of the carbody. The project included the introduction of the new livery, replacement of seats and other interior modifications, installation of new components, and modification of the roof for the installation of air conditioning units. Replacement and cleaning of electrical components were not included. The 31 remaining LRVs that were not modernized in Phase 1 underwent refurbishment in 2004, carried out by the Light Rail Transit Authority. This involved the replacement of the electrical components of  the trains, along with additional works in the 32 refurbished LRVs. Refurbishment was completed in January 2008. Second refurbishment (2016–2017). In September 2012, the then-Department of Transportation and Communications (DOTC) and the Light Rail Transit Authority (LRTA) announced a rehabilitation program for the trains as part of the LRT Safety, Reliability and Capacity Improvement Program of the DOTC which aims to rehabilitate the line. 23 trains were planned to be repaired, including the rehabilitation of 21 1000 class vehicles. This plan however was not realized. When the Light Rail Manila Corporation (LRMC) took over the operations and maintenance of  Line 1 on September 12, 2015, only 77 LRVs across the three types of trains that run in the line were operational. To increase the running trains and reduce the headway, the company initiated the second refurbishment of the trains in 2016 worth . Twenty-five LRVs underwent restoration as part of the second refurbishment. The refurbishment includes the removal of rust from the carbody, repainting, replacement of flooring, and installation of new LED lightings and signaling systems. Out of service trains were also repaired and reentered revenue service. LRMC contracted Joratech Corporation for the second refurbishment of the trains. Restoration  of the twenty-five LRVs were completed in May 2017, increasing the number of available LRVs to 102. As of November 2020, there are 33 light rail vehicles that underwent the second refurbishment. Themed trains. When the Light Rail Manila Corporation took over the operations and maintenance of Line 1 in 2015, the railway operator began placing special themed decorations in the 1000 class LRVs since 2016. These include the yearly Christmas-themed and Valentine's-themed trains, special COVID-19 pandemic and vaccination-themed decorations, and a special ""Gabay Guro""-themed train for teachers. Gradual retirement and decommissioning. With the testing and  commissioning of the 13000 class LRVs, the 1000 class LRVs will be gradually decommissioned. As of 2021, there are eight decommissioned 1000 class LRVs. These were previously stored at the LRT Line 1 Baclaran Depot until these were transferred to the LRT Line 2 Santolan Depot due to the expansion of the former.
