1 Line2 (Ben Thanh An Suong Section) Feasibility Study on HCMC UMRT Line2 (Ben Thanh An Suong Section) E&M System : Rolling Stock Tsukuba Express (Japan) Odakyu Line (Tokyo, Japan) MARCH 2008 JAPAN RAILWAY TECHNICAL SERVICE (JARTS) Under Financial Assistance by METI, JAPAN Definition of The Study The Study was conducted by JARTS under METI FS scheme, JAPAN The Study Period was 2months, February March 2008 The Collaboration with ADB Study Team for Lines 2 and 3 was made, based on the discussion between METI and ADB in January METI Study Team was provided the demand forecast results, inventory of buildings, and other information from ADB Study Team. iii

2 Line2 (Ben Thanh An Suong Section) Objectives of The Study To assess the possibility to apply Japanese Railway Technology to the rail system for HCMC UMRT Line2. To assess integration of the operation and maintenance of the rail system as UMRT Network with Line1 system, which has been financed by JBIC and to be applied STRASYA specification. Overall Route and Alignment of Line2 Route Length : 11.4km Number of Station: 10 Stations Gauge: 1,435 mm Electrification system: DC 1,500V Overhead Catenaries iv

3 Line2 (Ben Thanh An Suong Section) Basic Concept of Civil Engineering Design 1. Eastern Terminal is Ben Thanh Station for Phase1 for flexible extension route for Phase2 to Thu Thiem New Urban Center. 2. Access Track between Line1 and Line2 is proposed, which become possible to utilize the workshop of Suoi Tien (Line1) for full inspection of Line2 rolling stocks. 3. Location of Platform of Ben Thanh is arranged just below the Line1 platform for convenience of transfer passengers 4. Applied Multiface Shield Tunneling Method with required width of 11m only. 5. Distance between stations is adjusted around 1km for all the residents along the route to be convenient to access to Line2. Keep flexibility to access to Thu Thiem New Urban Center Thu Thiem Urban Development Master Plan Ben Thanh Station Viewed from A point End of Phase1 section A For flexible Access to Thu Thiem New Urban Center Viewed from B point C B Viewed from C point Access to Thu Thiem New Urban Center v

4 Line2 (Ben Thanh An Suong Section) Ben Thanh Junction Station Line2 plat form should be at below Line1 platform for convenience of transfer passengers Connecting Line between Line1 and Line2 is provided for common use of Suoi Tien Workshop for full inspection/maintenance Ben Thanh Junction Station shall be implemented together with Line1 construction works. Ben Thanh Terminal Line2 platform to be located just below the Line1 Platform Access Track Application of Multiface Shield Machine Mutliface shield tunnel to apply Narrow section of Cach Mang Thang Tam Street. No affected buildings above the shield tunnel except cut & cover sections for station construction. vi

5 Line2 (Ben Thanh An Suong Section) Application of STRASYA Specification The urban railway in Japan transport 50 million passengers daily with an average delay time of less than one (1) minute. STRASYA has been compiled by Japanese Railway Operators using their own specifications. It is unlike the systems proposed by manufactures. STRASYA emphasized to apply advanced signaling system to minimize the potential for train collision, and the train designed to be light weight which requires less energy to operate, less noise, and less deterioration to the track. Standardization of the size and basic structure of the cars is the key to the STRASYA specification. The profile and interior of the cars can be designed respectively. Philosophy for Integration with Line1 Common use of Workshop Access track between Line1 and Line2 to be provided Demension of Rolling Stocks should be same as Line1 Unification of Passenger Service Facilities Ticket system, Fare adjustment rule, Passenger information manners Integration of OCC in Suoi Tien Depot at Line1 To reduce backup staff Same O&M Company to manage the both Lines To reduce O&M Staff about 120. vii

Finishing Work) E & M Rolling Stock Depot Construction / Procurement Civil Works (incl.

By shortening 1 year of Project Implementation Period, the cost saving for Price escalation is about 60. Institutional Plan (O&M Company) O&M Company for HCMC UMRT Network is under preparation by Line1 Project, with 470 staff considering outsourcing the maintenance staff. If the same O&M company takes management activities for Line2, about 365 additional staff for Line2 O&M will be required. Assuming 120 staff would be saved if compared with the case that a separate O&M company be set up for managing Line2. ix

8 Line2 (Ben Thanh An Suong Section) Economic and Financial Evaluation Economic Evaluation Financial Evaluation IRR EIRR = 16.0% FIRR = 1.3% NPV NPV=327.3 NPV=744.9 Very high economic viability of Line2, but critical condition in financial viability, due to low setting of ridership and fare. The results indicates that the project should implemenent as early as possible for economic development of HCMC, but the financial back up for the government should be essential. It is desireble that Vietnamese Government shall apply foreign soft loan such as JBIC STEP Loan with very low interest and long grace period. Loan Repay ability Option A:JBIC STEP Loan: Interest: 0.2% Repayment :40 years (10 years grace Period) B: Other Loan: Interest: 4.0% Repayment: 25 year (8 years grace period) Total Balance 939 1,726 Maximum deficit ,792 Turning year to be positive annual balance Turning year to be positive cumulative balance 2043 Loan condition is much affected to financial condition of O&M implementation. The difference of total balance for 50 years are more than 2,700, by which two more MRT Lines could be developed in HCMC. ー x

9 Line2 (Ben Thanh An Suong Section) Conclusions of METIFS for Line2 STRASYA is applicable for Line2, which can be flexible to change in the detailed specifications, Demand forecast for Line2 is reasonable, with 14,700 pax/hour/direction in 2015, which is about 1.5 times of Line1. Phase1 of Line2 shall be Ben Thanh Tan Thoi Nhat of 11.4 km, but the cost should be further reviewed base on the detail geological and topographic investigations. Project Implementation period is set up with 6.5 years after signing of Loan Agreement with donors, if direct order of GC is conducted by HCMCPC. The loan condition is highly affected to the financial conditions of O&M bodies. It might be two more MRT Lines can be constructed by saving expenses if JBIC STEP Loan of 0.2% interest, 40 years repayment period, and 10 years grace period, is applied. Recommendations by METIFS Team 1. Inter operability of Line1 and Line2 should be secured for common use of workshop and other facilities, 2. Detailed topo survey, geological investigation, utility survey should be conducted by MAUR to grade up the accuracy of cost estimation and project implementation program, 3. EIA and RAP formulation should be done by MAUR to apply soft loan, such as JBIC STEP Loan. It is required to complete the EIA and RAP at least 4 months before appraisal of the loan. 4. MAUR shall request JBIC to conduct SAPROF to follow up the Line2 technical issues, which will be included field investigation, designing of Ben Thanh Stations, standard design of undergroud and elevated stations, details cost estimate of underground works and etc. xi
