History

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.

The 3rd-generation trains started operations 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.

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.

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.

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

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

  • Wheelchair strap and space, and fire extinguisher

Drive unit

The bogie is inside frame type with 600 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)

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.

Operations

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

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. No passengers were injured.
