on strike, paralyzing Line 1 operations from July 25 to August 2, 2000. Consequently, the LRTA did not renew its operating contract with METRO Inc. that expired on July 31, 2000, and assumed all operational responsibility. At around 12:15 pm on December 30, 2000, a bomb—later learned to have been planted by Islamic terrorists—went off in the front coach of a Line 1 train pulling into Blumentritt station, killing 11 and injuring over 60 people in the most devastating of a series of attacks that day, now known as the Rizal Day bombings. The Line 2 project (2003–present) With Japan's ODA amounting to 75 billion yen in total, the construction of Line 2 began in the 1990s, and the first section of the line, from Santolan to Araneta Center-Cubao, was opened on April 5, 2003. The second section, from Araneta Center-Cubao to Legarda, was opened exactly a year later, with the entire line being fully operational by October 29, 2004. During that time the Line 1 was modernized. Automated fare collection systems using magnetic stripe plastic tickets were installed; air-conditioned trains added; pedestrian walkways between Lines 1, 2, and 3 were completed. In 2005, the LRTA made a profit of ₱68 million, the first time the agency made a profit since the Line 1 became operational in 1984. A two-station, extension of Line 2 eastward from Marikina up to Masinag, Antipolo in the province of Rizal opened to the public on July 5, 2021. Line 1 concession (2015–present) On September 12, 2015, Light Rail Manila Corporation (LRMC), a joint venture company of Metro Pacific's Metro Pacific Light Rail Corporation (MPLRC), Ayala Corporation's AC Infrastructure Holdings Corporation (AC Infra), and the Philippine Investment Alliance for Infrastructure's Macquarie Infrastructure Holdings (Philippines) PTE Ltd. (MIHPL), started a 32-year concession for the operation and maintenance of Line 1 and the construction of a ₱65 billion extension project to Bacoor, Cavite. Infrastructure Stations With the exception of Katipunan (which is underground), the LRTA's 33 stations are elevated. They follow one of two different layouts. Most Line 1 stations are composed of only one level, accessible from the street below by stairway, containing the station's concourse and platform areas separated by fare gates. The boarding platforms measure long and wide. Baclaran, Central Terminal, Carriedo, Balintawak, Roosevelt and North Avenue stations on the Line 1, and all Line 2 stations are composed of two levels: a lower
