Old Oak Common (OOC) Enabling Works - GWML

[59CosG95]

Couldn't find a good place to start with the enabling works on the GWML for Old Oak Common "conventional" station, so here goes.

Colas Rail & the South Rail System Alliance (SRSA; of which Colas is a part) have been doing a fair bit of tweaking on the GWML to allow work at OOC to begin.

Old Oak Common Continue To Make Progress!

#TeamOOC have been been working hard on the Early Works Package A for the new rail systems alignment of the Great Western Main Line!


Over the last few weeks the team have:

✅Completed installing 1000m of ground and elevated trough route for the ATF and run out all the cables
✅Installed two new OLE structures to facilitate a headspan shortening
✅Installed two new OLE structures to transfer to a portal in the coming weeks

Keep up the great work team!

Looks like the headspan shortening follows the removal of the old reception line for OOC EMU depot (Reception Line 1) and plain-lining of all associated S&C. The two headspans in the pictures, J05/29 (1st pic) & J05/26 (2nd pic) were both 5-track and will now be 4-track.
The team have also installed new switches west of Acton Main Line to facilitate easier isolations around OOC: https://cutt.ly/xOvt1sO.

Thanks @mr_moo!
Passing through OOC just now, both the headspans mentioned above have now been shortened, and the new Series 1 anchor portal has now gained its boom.
The Up Side Double ATF feeder (2 cables on 1 insulator) is still on the old masts, but that looks set to go into the ground troughs. I suspect the old masts will go after that's done.

Yes the Relief Lines have been blocked on a few Saturdays and many Sundays due to the work required. The reception line still remains available for access to OOC depot for the Elizabeth Line, although one of the sidings/lines associated with the HEX depot has I think being marked OOU.

Can confirm that the Up side ATF has now been removed and presumably put in the 1000m of ground trough. The insulators remain but are bare.

Yep, removed by SRSA and converted to cabled ATF in troughing. It's sub-section 8001D for the Reliefs ATF.
