Just a heads up.  The final stage of the Bristol area resignalling/recontrol between Bristol(excl) - Chippenham (excl) and Westbury (excl) is taking place over the weekend 11/12 May 2019.

To answer a question which this may raise in the minds of some Temple Meads watchers:

Quote
Project phases
...
»  April 2019 – Bath corridor relock and recontrol to TVSC» (Thames Valley Signalling Centre - about);
»  Control Period 6 – possible remodelling of Bristol East Jn.

On completion of this work, Bristol Panel remains in service with just the south line from Parson Street towards Taunton. There is a plan to re-open the original terminal platforms at Temple Meads to provide more general capacity for trains terminating here, but the Panel Box occupies the throat. To decommission the panel, proposals are in hand to recontrol Bristol south area to TVSC in CP6 (Control Period 6 - The five year period between 2019 and 2024) after 2019.

In addition, an FTN node is located within the box and would need to be relocated. There are also plans for a Bristol Metro, of which Stage 1 (service to Portishead branch) can be accommodated within the existing layout. Future phases will be helped by the proposed remodelling of Bristol East Jn.

Fixed Telecomms Network - according to the Rail Engineer article.   (So is a node an exchange in other words?)

A FTN Node is a concentrator for the local hard wired network which then transmits/receives over a fibre optic link to/from a central point (aka an exchange).

Is this the work that was originally going to close Bath Spa for a few days over the Easter period?

I had a couple taken out a few years ago, when I was a bit poorly. There may be another use for the abbreviation, though.

(My bold)
Patchway/Parkway Phase 2, the introduction of Bi-Di through Filton Abbey Wood platform 2, Patchway, and Up Moves being allowed on the Down Tunnel (Patchway to Parkway) and Down Filton Main (Filton Abbey Wood to Parkway) and through Parkway platform 2, due for installation in November 2019.

Railway projects rule #4; there's never enough money to do it properly; there's always enough money to do it twice.

I seem to remember that when the full Plymouth/Cornwall scheme got postponed to CP6, there was a plan that when it did go ahead, control would move to Exeter rather than Didcot and that Exeter would also take over Bristol south.  Now that the full Cornish scheme has been delayed at least until CP7 and possibly CP8 (along with Glocuester and Worcester), I wonder what the latest plan for the remaining panel on Bristol PSB (Power Signal Box) is, the article above was written in 2016.

Yes, but thats not really a 'Stage' just tidying up and commissioning parts of a previous one that would have made ready at the original stage. Wink

Does this herald the fairly imminent closure of the signal control building at Temple Meads next to platform one or is this unrelated?

CP6 after 2019.

Meaning by the end of 2024, unless further delayed. Hopefully, it will be a lot earlier than that.
