The LRTA 1200 class is a class of high-floor LRV of the Light Rail Transit Authority (LRTA) in Manila, Philippines, which began operation in March 2007.^[8]

Purchase[]

In 2005, Sumitomo Corporation and Itochu Joint Venture Company Limited received an order of 48 Light Rail Vehicles (LRV) and signed a construction contract between Kinki Sharyo and Nippon Sharyo to supply 48 vehicles.^[4] The trains were provided by the Manila Tren Consortium and were ordered as part of the LRT Line 1 Capacity Expansion Project Phase 2.^[9][10] The capacity expansion project was funded by Japan's official development assistance.^[11]

Design[]

Structure[]

The train car body is made of beadless lightweight stainless steel, with composite materials on the indoor panels and aluminum on the inner bone to reduce weight.^[4] The LRV design is a 6-axle rigid body consisting of one articulated section. 1200 class LRVs have 4 electronic sliding doors on both sides.^[4] The car body measures 26,000 mm (85 ft 4 in) in length, 2,590 mm (8 ft 6 in) in width, and 3,430 mm (11 ft 3 in) in height.^[8]

Each mono-articulated car has two roof-mounted air-conditioning units that has a cooling capacity of 41,000 kcal (170,000 kJ). In total, there are eight air-conditioning units in a four-car train set.^[8]

During the production of the 1200 class trains, a mock-up model was displayed at the LRT Line 1 Baclaran Depot in Pasay City in 2006. The length of the mock-up model is 14,000 mm (45 ft 11 in) long, or just 54% of the 26,000 mm (85 ft 4 in) vehicle length.^[9]

Interior[]

The interior is color-toned based on light and dark two-color green in the seats to complement the landscape of Manila. Seats are made of fiber reinforced plastic and has an aluminum bracket type cantilever longitudinal seat for reducing weight. Seating and grip sticks are designed to have ergonomic dimensions, aside from equipment arrangement inside the cab.^[8] A wheelchair-compatible space is provided beside the gangway of the intermediate car, alongside an equipped fire extinguisher.

Bogie layout and drive unit[]

The bogies are of inside-frame type, similar to the 1000 class. Like all LRT Line 1 rolling stock, the wheel diameter is 660 mm (25.98 in). Each LRV has three bogies consisting of two motorized bogies at the ends of the LRV and one trailer bogie under the articulation.^[4]

The traction control system is IGBT–VVVF that drives the four main motors of the two carriages. The resistors are mounted on the roof for backup regenerative brakes. The VVVF controller is manufactured by Mitsubishi Electric, and it has Electronic Command braking device supplied by Knorr-Bremse that uses air and regenerative brakes.^[5]

Formation[]

Details of the car designations are listed below:

• MC - motor lead car
• M - motor car

Operations[]

The 3rd-generation trains were handed over to the Philippine government on December 9, 2006, with Japanese Prime Minister Shinzō Abe and former President Gloria Macapagal Arroyo attended the handover ceremony of 1200 series as part of the transportation capacity enhancement of the Manila LRT Line 1.^[4] The trains subsequently entered service in March 2007.^[8]

On February 25, 2010, a 1200 class train was used in a test run of the LRT Line 1 North Extension and the MRT Line 3 as part of the MRT-LRT Closing the Loop project that intends to integrate the LRT Line 1 and MRT Line 3 operations, but the integration of operations has not been pursued.^[14]

Out of the 12 sets, only 11 sets remain operational, with three light rail vehicles inoperable after a collision as of 2013.^[15]

The 1200 class trains operate in a 4-car configuration. However, there are some occurrences of 1200 class trains operating in a 3-car formation.

Special themed trains[]

In September 2018, a 3G trainset was decorated with a special "Gabay Guro" decoration to celebrate the National Teachers' Month in the Philippines. The decoration has a library-themed look with images of books. The special themed train was launched on September 6, 2018 and ended a year later.^[16]

Incidents[]

• On February 18, 2011, two trains (1G and 3G) collided near Roosevelt Station in Quezon City at the reversing tracks, around a kilometer away to the east. There were no passengers on board when the incident happened.^[17] This caused the Roosevelt and Balintawak stations to remain closed for two months until the stations were reopened on April 11, 2011. An investigation was conducted and was shown that one of the drivers was texting when the incident occured.^[18] This however caused one of the 3G units to be in idle state and has not yet been restored for service.
• On May 23, 2015, thousands of passengers were stranded after two trains (1G and 3G) collided near the Monumento station. A train driver was hurt after the impact caused his head to slam into the dashboard of the train.^[19] The accident, later revealed to be caused by power fluctuation that affected the signalling system, forced passengers to alight from the station until services was restored around 1 pm at the same day.^[20]
