You can head west from Stratford by three different routes and arrive at Liverpool Street but one of these is of course the London Underground Central line and all three will take you to different parts of Liverpool Street so this may well not count and definitely would not if it has to be three different directions out of the platforms.

That won't be easy though since the WECA lacks the council tax precepting powers which the other combined authorities have.  It would appear that South Gloucestershire Council will not agree to the introduction of such powers.

No, it is part of the North Somerset Unitary Authority.

Looking at the list for the South West at https://www.gov.uk/government/news/find-out-about-every-new-transport-project-in-your-region it includes
When in reality it will be reopening the two stations on the existing line.

Also seems Plymouth is finally back to hourly throughout the day after what will have been more  than  three years with some two hour gaps in service.  Not sure about the diagramming but could this mean more single  Voyager workings?

Edited, I was thinking too much about that early arrival into Plymouth when I was typing that.

The early morning  fast Plymouth service is no more.  Instead, there will be 0600 via Bristol service, calling at Reading, Didcot  Parkway, Swindon, Chippenham, Bath Spa, Bristol Temple Meads, Bridgwater, Taunton, Tiverton Parkway,  Exeter St Davids, Newton  Abbot, Plymouth and as then as before  to  Penzance.  This does however still provide an arrival in Plymouth  before 1000 which I believe was one of the reasons the current 0637 was introduced.

A three hour public journey time to  Plymouth will still be possible though with the 1004 to run non-stop between Reading and Exeter (as it used to do when it was the 1006 Cornish Riviera before December  2019) with a public arrival time in Plymouth of 1304 (1305 WTT^▸ (Working Time-Table)).

Changes to the building regulations relating to hot water supply and systems, specifically a requirement that hot water storage systems must include a feature which  prevents the temperature of the stored water exceeding 100 degrees C and that any discharge safety devices must be to a location where it is visible but not cause danger to people in the building.

They are still shown in the May 2017 timetable and although I do not have a 2018 timetable in front of me, the change was almost certainly in December 2019 when the timetable was recast to give a regular stopping pattern for most services to Plymouth/Penzance.  I believe Virgin did the same with their named trains on both XC^▸ (Cross Country Trains (franchise)) and West Coast back in the 2000s.

The only named train shown in the December 2019 D timetbale is the Night Riviera.

One change I note is that the the first direct service of the day from stations on the Berks & Hants to Plymouth 1C85 (1436 from Paddington) will run to Paignton instead (arriving at 1744).  It will then form 1A98 departing from Paignton at 1902 (instead of the 1857 from Plymouth) and calling at Torquay, Torre, Newton Abbot, Teignmouth, Dawlish and Dawlish Warren where it is overtaken by 2U32 Penzance to Cardiff Central (not sure I've ever seen an intercity service to London getting overtaken by a regional service at Dawlish Warren before).  After reaching Exeter it then runs as previously to Paddington.

It's only fully hourly as far as Bristol, there are some two hours gaps west of there.

The DfT^» (Department for Transport - about) have published a prior information notice for a direct award which is anticipated to be for a duration of between three and six years.

6 is Penzance.

The 1982 WTT^▸ (Working Time-Table) shows a DMU^▸ (Diesel Multiple Unit) service from Reading to Bedwyn running roughly every 2 hours off peak and the 1989 Paddington Station Workings do not show any Paddington to Bedwyn services off peak so it would seem to be the case that the regular service from Paddington was not introduced until the arrival of the turbos.  I wonder if the turbo service from Paddington was initially all stations west of Reading or if the Reading to Newbury shuttle was introduced at the same time, giving Newbury 2 trains per hour from Reading off peak (quite an improvement from what was on offer in 1982)?
