2 Introduction to Manila Urban Rail Transit System Manila rail transit lines LRT1: country’s oldest light rail transit system started commercial operation in 1984 LRT2: newest rail transit system started commercial operation in 2004 MRT: built under Build-Operate-Transfer (BOT) mode; in 35 years will be state-owned Philippine Ministry of Transportation responsible for railway infrastructure construction. Responsibility divided between LRTA and MRT. Most of LRT1 and MRT equipment is old and frequently fails Status of railway SI LRT2 Telecom: STE MRT: Signaling: Bombardier LRT1 and LRT2 Signaling: Siemens *DOTC LRTA MRT LRT1LRT2 * Dept. of Transportation and Communications

3 MRT Purple Line (MRT Line 2) MRT line 2 is 13.8 km long with 11 stations, including 1 underground and 10 overhead stations, 6 transformers, 1 depot, and 1 OCC. Electronic network equipment includes SDH (Alcatel), CCTV, PBX (E&M), radio, public address, PIDS, Clock, SCADA, AFC (Thales), and signaling (Siemens). Unified multiple service communications over fixed network includes signaling, AFC, and SCADA. Single wireless network for analog radio system (TAIT of New Zealand). DEPOT (OCC)

5 Existing Network Solution Unified, multiple-service SDH STM-1 backbone network; optional X 1650SM-C on each station. Signaling system uses 4-wire RS485 and 4-wire audio to connect to backbone. SCADA uses 4w RS465 to connect to backbone. Public Address System (PA) uses audio tunnel to connect to backbone. Clock and PIDS use 4w RS485 tunnel to connect to backbone. AFC connects to router through Ethernet interface and router connects to SDH through E1. Radio connects to backbone through E1. CCTV is connected through optical fiber tunnel. PBX is connected through E1 tunnel. DEPOT (HQ) SANTOLAN ANONAS J. RUIZ PUREZA RECTO LEGARDA V.MAPA GILMORE CUBAO KATIPUNAN SDH RING SCADA CCTV PBX Clock SCADA PIDS APS IL AFC TC Radio
