HA NOI (VNS) — The
Ministry of Transport (MoT) issued a press release yesterday saying that the
controversial wavy line of an under-construction urban railway project observes
the release, the 13-km Cat Linh-Ha Dong Urban Railway project, which has
stirred public debates lately as it is being built in a wavy instead of straight
line, has been examined for all criteria. It has been found to meet the technical
standards to ensure safety once it becomes operational, the release added.
is built following China's Code for Design of Metro GB50157, in which a slope
is allowed from 0 to 30 per mille of the total stretch. In the case of Cat
Linh-Ha Dong Urban Railway, the slope for arrival and departure at each
station has been measured maximally at 23 per mille, the allowed range.
The MoT assured
that the project will become operational only once it passes every safety requirement.
Linh-Ha Dong Urban Railway project is built in EPC
(engineering-procurement-construction) mode under China's official development
assistance in line with a contract signed in 2008 between the governments of
Viet Nam and China.
The railway line
has been designed on the 1,435mm-track gauge with 12 stations. Under the
project, 13 Chinese-made trains were purchased recently, which will be operated
on the frequency of one train every two minutes. The designed speed is 35kmph.
when the public raised questions about the logic and safety of the wavy line,
Le Van Duong, deputy director of the project management unit, said that the
rails were deliberately designed that way to optimise the operation of trains
in terms of efficacy and energy consumption.
He explained that the railroad's design was based on the principle that a
train went up when entering a station, which requires braking, and went down
when leaving the station, when it needs to speed up. — VNS
