successfully, following Beijing, Tianjin, Hongkong and Shanghai. Guangzhou Metro Line 1 is the largest in urban construction projects since the founding of Guangzhou. It runs from east to west, begins at Xilang Station, passes through Pearl River Tunnel, goes under the central part of the city, and reaches at its terminal Guangzhou East Railway Station. The total length of Metro Line 1 is 18.48km (16,4km underground),with 16 stations, one depot, one operation control center(OCC).The investment budget is hour per direction, and the daily ridership is 1.13 million persons, which can meet the requirements expected in the year 2023.It is financed and constructed by Guangzhou Government. The capitals are funded from a variety of sources, such as governmental finance, societal raising, property development and foreign loans. Germany, Britain, Japan and USA supply the foreign funds, $541 million.Trains and most major electric and mechnic (E&M) systems installed in stations and tunnels are financed by the German Government, through the “Kreditanstalt fuer Wiederaufbau”, manufactured and supplied by a German Consortium of Siemens and ABB Daimler-Benz Transportation (A dtranz) under the leadership of Siemens.The training was executed by an international team of training experts under the responsibility of Hamburg-Consult, a subsidiary of HHA(Hamburger Hochbahn AG),Germany, in close co-operation with the nearby Hongkong Metro.An Initial Stage service from Huangsha to Xilang (5.4km) for visiting passengers already commenced on 28.06.1997,with a safe and reliable operation just from the very beginning, without any accidents or major incidents.From 16.02.1999 on (Chinese New Year) an extended service for visitors is foreseen on the entire Line1, shared with the remaining activities in commissioning, integrated test and trial operation. Hand-over of the Metro Line 1 to the public of Guangzhou for full revenue service is scheduled for 28.06.1999.2. State-of-the-art StationsGuangzhou Metro Line 1 has sixteen stations. XILANG and KENKOU are surface stations and others are underground stations. The decorations of the stations are spacious, bright and refined. There is no pollution due to use of power. Fresh air, comfortable temperature and humidity are kept because of the good ventilation and air conditoning systems. In the stations, there are bank offices, ATM, magnetic car phones, small shops as well as guiding zone for vision-handicapped people and hydraulic elevator for disable people. Mobile phones and pagers can be used in the underground stations. Shopping streets are providing for the passengers. The construction of Metro Line 1 was commenced on December 28, 1993. The construction methods include cut- cover tunnel (3.5 km), mining (7.2 km) and shielding tunnel (4.5 km) by 3 boring machines with a diameter of 5.2 meter. The immersed tubes are used in the underwater section (1.2 km) passing Pearl River.3. Advanced Metro EquipmentMetro is an industry with modern high technology. The performance of the equipment for Guangzhou Metro has reached the advanced level of the early 1990s in the world. There are 15 E&M systems imported from Germany, Britain, Japan and USA.All equipment is most advanced state-of-the-art Metro material.

Management and OperationUnder the leadership of the People’s Municipal Government of Guangzhou, Guangzhou Metro Corporation(GMC) was commissioned in 1992 to carry out the construction of the Metro network which is based on studies of leading Chinese Design Institutes, as well as to manage all urban rail transit facilities and develop other varieties of business in Guangzhou. The Metro is operated by OCGM (Operating Company Guangzhou Metro), a subsidiary of GMC.Since its establishment, the Corporation has made impressive achievements on metro construction. This great accomplishment reveals the firm and indomitable spirit and excellent teamwork of the metro staff.Guangzhou Metro Corporation stresses on high-qulity service and corporate culture. A staf team, full of vigor and vitality, can undertake all kinds of difficulties, is cultivated and established simultaneously with the metro construction.In 1999, the ticked fare for a whole journey is 6 yuan/person. The rate is decided on gradual bases. The initial price is 2 yuan/person. Proper discount will be given for passengers with value-stored pass, disabled soldiers and students in primary and secondary school. At present, the operating costs are almost balanced by ticket revenues, considering average daily 180,000 riders during revenue operation for 3 months.·Management ObjectivesAs a “window”profession to serve for the public, Guangzhou Metro assumes actively its own responsibilities. We take “advanced equipment and first-class service” as their management philosophy. In addition to focusing on excellent technical performance, great emphasis was also placed on training personnel to manage, operate, and maintain a safe, reliable, comfortable, and customer-service orientated Metro system.·Operation Management SystemIn order to realize safe and reliable operation with high quality and efficiency, simplified and efficient operation management organization and perfect operation management system are established by Guangzhou Metro. They organize the train operation and provide the operation service to the public according to the objective regulations of urban rail transit and the distinguished features.Under the principal of centralized dispatching and unified command, a series of rules and regulations are specified to standardize the activities of each department, such as operation organization, repair and maintenance of rolling stock equipment, equipment operation management and safety assurance etc. Centralized command and separate level control are performed with computers.4. Build Guangzhou’s New FutureGuangzhou’s objective is to build a modern metropolis in the world. However, traffic congestion and serious pollution has become day the bottleneck for the development. Guangzhou Metro Corporation has been making unremitting efforts for the development of Guangzhou’s traffic, striving to build a new future for the traffic in Guangzhou. Guangzhou Metro will be extended continuously in all directions. Up to the mid-21st century, an urban rapid rail transit network with seven lines (206.5km)will be formed in Guangzhou. It will come to the fact that“ride with metro and travel all over Guangzhou”.
