Re­tain­ing wall work starts at sta­tion

Kalamunda Reporter - - News -

WORK is pro­gress­ing on the For­rest­field sta­tion in High Wy­combe as part of the For­rest­field-Air­port rail link.

The first 18 of 92 pre-cast con­crete pan­els, which will form a re­tain­ing wall along the east­ern side of the sta­tion, have been craned into place.

The re­tain­ing wall will run the length of the sta­tion and sep­a­rate the ground-level bus interchange from the train line, which sits at a lower grade.

Ex­ca­va­tion work also con­tin­ues at the Air­port Cen­tral sta­tion

Con­struc­tion of the sta­tion box struc­ture is con­tin­u­ing in readi­ness for the ar­rival of tun­nel bor­ing ma­chine Grace in the new year.

Ground-level slabs have been com­pleted and ex­ca­va­tion to concourse level is al­most 70 per cent com­plete.

The con­struc­tion team have so far ex­ca­vated to a depth of 8.5m. When com­plete, the train line within the sta­tion box will sit 15m be­low ground level. Works are also on track at Bayswa­ter. The tem­po­rary re­lo­ca­tion of the Mid­land line is tak­ing shape, with much of the re­quired track near Rail­way Pa­rade now laid.

A se­ries of out-of-hours works is re­quired in late Novem­ber and early De­cem­ber to en­able con­struc­tion close to the ex­ist­ing rail, with­out trains op­er­at­ing.

The tem­po­rary line is ex­pected to be ready for its first train in mid-De­cem­ber, af­ter which the ex­ist­ing Mid­land line will be re­moved to al­low for the con­struc­tion of the Bayswa­ter dive struc­ture.
