Management Authority for Urban Railways Chapter 5 – Service Operations Plan
5.3.2 Structure of Services
126. The schedules of service will start at 5.00 a.m. and finish at 12.00 p.m. On working days the
peak periods are considered to be 6.30 a.m. to 8.30 a.m. and 4.00 p.m. to 6.30 p.m. (based on the
transport demand distribution). Evening service will operate for 4 hours, from 8.00 p.m. to 12.00 p.m. It
is anticipated that on Sundays and holidays the demand distribution will have less significant peaks.
5.3.3 Service frequency
127. Table 5.3-1 summarizes the service frequency for years 2015, 2025 and 2035. Service
frequency for the peak period is derived from the design demand (pphpd) described in Section 5.2 and
train capacity of 695 passengers per 3-car trains (5 passengers per m 2 ) in 2015 and 1,390 passengers
per 6-car trains in 2025 and 2035. For off-peak, evening service, Sundays and holidays, the service
frequency is determined based on the assumed proportional demand described in Section 5.2, with a
minimum acceptable service frequency of 12 minutes.

5.3.4 Commercial Speed
128. The commercial speed for Line 2 – Ben Thanh – Tham Luong was estimated taking into
account the running time between stations, the reserve time (and, thus, running time with coasting)
and station dwell time. The running time and reserve time between stations was calculated with
specific tool used for the Paris Transit system (RATP) called MATYS, taking into account the train and
line’s characteristics described in the previous chapter. The dwell time was calculated based on
estimated boarding and alighting per station, the number of doors (4 doors per car) and lanes per door
(2 lanes per door) in the train, the passenger flow rate (1 passenger per lane per second), the
headway, and the time required for technical reasons (door opening, door closure warning time and
door closing).
129. The total estimated running time from Ben Thanh to Tham Luong (Track 1), a distance of 9.53
km, is 930 seconds, with a resulting commercial speed of 36.9 km/h. From Tham Luong to Ben Thanh
(Track 2), the total estimated running time is 945 seconds, with a resulting commercial speed of 36.3
km/h. The Technical Paper Operations Plan, provides a detailed description of total running times,
including speed/distance between station diagrams.
5.3.5 Fleet Size Calculation
130. The calculation of fleet requirements to meet the forecast patronage demands at 2015, 2025
and 2035 are given below. Fleet requirement is determined by the total estimated running time
detailed in the previous paragraph, plus the last stations’ track changing time and regulation time at
terminal (280seconds at Tham Luong and 320 seconds at Ben Thanh), divided by the target schedule
presented in Table 5.3-1 for the peak period.
