The Shenzhen Metro Phase 1 network, now in operation comprises two lines, Line 1 (L1) between Lo Wu and the "Windows of the World" in the east-west direction, and the first phase of Line 4 (L4) connecting Huanggang Boundary Control Point with Shaoniangong in the north-south orientation. Interchange between L1 and L4 is provided at Huizhanzhongxin Station. The Phase 1 network, comprising 20 stations, has been opened for service on 28th December 2004.
The Shenzhen Municipal Government plans to expand the rail network by constructing 8 new extensions, of which 4 are metro lines (new Lines 2 and 3, and extension of Lines 1 and 4) whilst the remainders are fast regional light rails (Lines 6, 8, 11 and 12) by 2010 (See Figure 1 for the proposed rail network for Shenzhen).
The extension of Shenzhen Metro L4, i.e. Phase 2, forms part of the major delivery programme of the overall rail development plan in Shenzhen. Shenzhen Network Shenzhen Network

:linkText:more Project Description
The Shenzhen Metro Line 4 Phase 2 project is a vital part of the Shenzhen overall rail expansion plan. It forms a logical extension of the Line 4 Phase 1 rail line, extending northwards from Shaoniangong Station (Juvenile Activity Centre) to Qinghu Station.
Line 4 Phase 2 is approximately 15.8 km long, consisting of approximately 5 km of underground section and 10.8 km of at-grade and elevated sections. It has 10 stations, i.e., two underground stations, one at-grade station, and seven elevated stations. In addition, a maintenance depot will be constructed at Longsheng Station. The two underground stations and the associated tunnels will be constructed using drill-and-blast method and Tunnel Boring Machine which is specially built for this project.
The total project cost is approximately RMB6.0 billion, which is 100% funded by MTR as an investment project. This investment railway project is expected to complete by September 2010. MTR has established a subsidiary company in Shenzhen, MTR Corporation (Shenzhen) Limited, to undertake the project management of this investment project in Shenzhen.
The project also involves the acquisition of property development rights from the Shenzhen Municipal Government along Line 4 with an aggregate gross floor area of 2.9 million m2.
On 26th May 2005, MTR Corporation initialled a Concession Agreement with Shenzhen Municipal Government on the investment, construction and operation of Shenzhen Metro Line 4.
On 4th November 2005, the groundbreaking ceremony for the Phase 2 Trial Section was held in Shenzhen. Mr Xu Zongheng, Mayor of Shenzhen Municipal Government was one of the officiating guests. :linkText:more Progress Update - September 2008
Design The feasibility study report ("FSR") is being reviewed by the National Development and Reform Commission. For civil design, preparation of the phase II architectural finishes drawings is in progress.
Procurement Tendering of all major civil works was completed. Advance trial section contracts have been awarded. Apart from the rolling stock and signalling systems, tendering of other electrical and mechanical contracts was completed. Advance E&M works contracts have also been awarded.
Construction
Underground Section For the tunnel section from Shaoniangong to Lianhuabei, drill and blast excavation is in progress. For the tunnel section from Shangmeilin to Minle, drill and blast excavation of 1068m tunnel was completed at the south of Danaoke Mountain and 1207 bored piles were completed at the open cut tunnel. For Shangmeilin Station, track slab, concourse slab and plant level slab were completed. For Lianhuabei Station, 85% of capping beams has been completed.
Viaduct Section All pile caps were completed at the Minle Station, Hongshan Station and Longsheng Station. For Longhuazhongxin and Qinghu Station, pile cap works are in progress whereas 73% of pile caps has been completed at Baishilong Station. For Longtang Station, concourse level structure was completed.
For the viaduct section from Longsheng to Longhuazhongxin, 46% of viaduct piers has been completed. For viaduct sections from Hongshan to Longtang and from Longtang to Longsheng, viaduct deck construction is in progress. For viaduct sections from Longhuazhongxin to Qinghu and from Minle to Baishilong, 91% of bored piles and 86% of bored piles have been completed respectively.
Depot Area 78% of bored piles and 32% of pile cap have been completed.
Electrical & Mechanical (E&M) Works Design works for building services and tunnel ventilation system, power supply system, trackside auxiliaries and automatic fire alarm system are in progress. Excavation at Lianhuabei Station
