During two 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.
A further shutdown will be required to tie in rail systems (e.g. signalling, communications) in mid-February.
Works also continue on the principal shared path (PSP) alongside Whatley Crescent. A section on the western end of site has been asphalted. On the eastern end, part of the existing PSP needs to be demolished and rebuilt to meet the new alignment. Once completed, the asphalt will need to set for 28 days before line markings can be applied.
The section of the PSP located within the site boundary will remain closed until all construction 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.
At the eastern end of the site, the 25kV Track Sectioning Cabin has been connected to the overhead power supply infrastructure within the dive structure. Located next to the Bayswater tunnel portal building, automated switches within the cabin control the 'neutral zone', a non-electrified section between the Airport and Midland lines.
Works are also wrapping up in and around the portal building, with earthworks and drainage installation underway on the outside and commissioning activities in the lead up to the final energisation ongoing on the inside.
Demobilisation of crib rooms and equipment is scheduled for the beginning of March.
