During the recent 56-hour shutdowns in February and March the final shift of the Midland Line tracks was completed and the new section of the alignment commissioned.
These tracks are now located in their permanent locations just south of their original location, following temporary relocation in December 2017 to make room for the construction of the Bayswater Junction dive structure.
Next steps include noise and vibration monitoring during the month of April, as well as a series of nightworks:
|Dates and hours of works
||Activity and equipment
Monday April 26 to Friday April 30
9pm - 4.45am
Activities will include:
- rail cutting and welding
- installing a signal foundation
- moving ballast
- survey works
- working within the dive structure.
Equipment includes front end loader, franna crane, digger, plate compactor, excavator, dump truck and hand tools.
A further shutdown will be required to tie-in rail systems (e.g. signalling, communications etc.) later this year.
Works also continue on sections of the principal shared path (PSP) alongside Whatley Crescent. This includes installation of services, fences and asphalt.
The section of the PSP located within the construction boundary will remain closed until the project is completed, with the current diversion along Whatley Crescent staying active. While work and heavy vehicle movement is still ongoing, this is the safest option for cyclists and pedestrians.
Planting of trees and other vegetation along the alignment will be undertaken in spring 2021 when asphalting works around the PSP are complete.
Fit-out of the portal building is ongoing, with recent works including fitting of louvres to enable airflow to the tunnel ventilation fans. Scheduled for April is the installation of the lift car, which can transport passengers from the tunnel to the surface in case of an emergency.
