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, the first train completed in December 2005.[4] The trains were provided by the Manila Tren Consortium and were ordered to as part of the LRT Line 1 Capacity Expansion Project Phase 2.[6][7] The capacity expansion project was funded by Japan's official development assistance.[8]

Design

Structure

The 1200 class' carbody is made of beadless lightweight stainless steel, with composite materials on the indoor panels and aluminum on the inner bone to reduce weight.[4]

Each LRV is bi-articulated with inside-frame bogies which are 26 mm (1.0 in) in length. The carbody 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.[5]

1200 class LRVs have 4 electronic sliding doors on both sides.

Each mono-articulated car has two roof-mounted air-conditioning units that can generate 41,000 kcal (170,000 kJ). In total, there are eight air-conditioning units in a four-car train set.[5]

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.[5] A wheelchair-compatible space is provided beside the gangway of the intermediate car, alongside an equipped fire extinguisher.

Drive unit

The bogie is inside frame type with 660 mm diameter, the wheels are the same as the 1100 series, and the traction motors are Three-phase AC Induction motor producing 105 kW (141 hp).

The traction control system is IGBTVVVF 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.[9]

Safety Systems

The 1200 class are operated with Automatic Train Protection and Automatic Train Stop and has disc brakes on the bogies.

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.[5]

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.[11]

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.[12]

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.[13] 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.[14] 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.[15]
