Bristol PSB (Power Signal Box) still controls Bathampton junction to Keynsham, and Cogload jn to Parson Street (exclusive).  The first of these will transfer to TVSC» (Thames Valley Signalling Centre - about) in April 2019 when BASRE (Bristol Area Signalling Renewal and Enhancement) stage 3 goes ahead.  (Temple Meads was stage 4 - don't ask!). Bristol South resignalling has been postponed - no idea when the PSB will actually shut.

Yeah knew it had all gone a bit out of order, and Cogload to Parson St was staying for now, but didn't realise we still had Bathampton to Keynsham too...

Good job Stoke panel had already been switched out a while ago or Bristol PSB (Power Signal Box) would now still be controlling almost everything around Bristol except Temple Meads itself!

Oh for the day when I can catch a train from Mangotsfield to the Centre, Bath and Yate!  ;-)

When Bristol Panel box opened on 23/24 August 1969 it initially controlled Bathampton to Limpey Stoke only so a mirror of the de-commissioning Wink

Isn't Cogload controlled by Exeter PSB (Power Signal Box)?  I thought the border was around Fordgate for Bristol Panel and around Athelney with Westbury Panel on the Berks & Hants route.

At about 4pm and again just after 6pm last night there were major signalling problems around BTM (Bristol Temple Meads (strictly, it should be BRI) but BTM is a commonly used alternative)), was this related to these "improvements"?

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.
