South Island Line (East)
Operational Ground-borne Noise Mitigation
Measures Plan
MTR Corporation Limited
July 2014
Background
Referred to the EP Condition 2.26 (EP-407/2010/D), MTRCL shall deposit with the Director of
EPD an Operational Ground-borne Noise Mitigation Measures Plan showing:
(a) Type 1a Trackform – Resilient Baseplate shall be installed at the track section
between Chainage 16730 and 16980 as shown in Figure 10; and
(b) any additional or changes in noise mitigation measures as required in accordance
with the Operational Ground-borne Noise Review Plan deposited under Condition
2.25.
Review of the upgraded trackform for SIL(E)
In accordance with the approved SIL(E) EIA report, Type 1a trackform was proposed along
the SIL(E) alignment. With reference to Section 3.5.2.3 of the approved SIL(E) EIA report, full
compliance with the ground-borne Acceptable Noise Level (ANL) could be achieved by the
use of incline turnout and Type 1a resilient baseplated trackform within the SOH station
between chainage 16730 and 16980. It was verified in the Operational Ground-borne Noise
Review Plan submitted under EP Condition 2.25 (EP-407/2010/D) with updated on-site
measured Line Source Response and ground vibration conditions.
With a more conservative approach for better performance and service to the community,
an upgrade of trackform would be employed in SIL(E). A review of the upgraded trackform
provision and the trackform proposed in the approved SIL(E) EIA Report is summarized in the
Table 1.1 below:

Remarks:
1. Type 1a Trackform is the resilient baseplated trackform with stiffness of 25 kN/mm
2. Type 1 BCT (Baseplated Concrete Tie) Trackform is the resilient baseplated trackform with track
slab casted in-situ with sleepers. The trackform assembly is the same as Type 1a and using Delkor
Alt 1 Baseplate with track stiffness of 20-25 kN/mm
3. Turnout Trackform is trackform at turnout location with resilient baseplate pad with overall
stiffness of 25 kN/mm and inclined at 1 in 20
4. Type 1 FST (Floating Slab Track) Trackform is the resilient baseplated trackform with precast slab
supported by rubber bearings underneath. The trackform assembly is the same as Type 1a and
using Delkor Alt 1 Baseplate with track stiffness of 20-25 kN/mm
5. Type 2 Trackform with Web Supported Baseplate is the resilient baseplated trackform with track
slab casted in-situ with sleepers. The baseplate is Vanguard Baseplate and track stiffness of 3-5
kN/mm
As shown in the Table 1.1 above, the type of trackform proposed in the approved SIL(E) EIA
Report would be upgraded to BCT Trackform, Turnout Trackform, FST Trackform with Delkor
Alt 1 baseplate or Type 2 Trackform with Vanguard baseplate. The track schematics of SIL(E)
are shown in Appendix 1 and results of performance test for different trackfroms are given
in Appendix 2.
The upgraded trackform is more resilience than that proposed in the approved SIL(E) EIA
report, and hence would have better vibration attenuation. With the upgrade of trackform,
the ground-borne noise impact from the operation of SIL(E) on the community will be less
than it is predicted in the EIA Report.
