Ouch, this has coincided with an open day at Bath University and an event at the racecourse.

Horrendous scenes at Bath Spa railway station — where hundreds of people are stranded due to delays and cancellations.

Isn't the road outside Bath Spa shut too?

I think 1 is Weymouth. 

17:37 Swindon to Westbury due 18:22
18:35 Westbury to Swindon due 19:17

18:35 Westbury to Swindon due 19:17 will be cancelled.
This is due to a fault with the signalling system.

Cancellations to services between Chippenham and Bristol Temple Meads

Due to a fault with the signalling system between Chippenham and Bristol Temple Meads all lines are blocked.
Train services running through these stations may be cancelled, delayed or diverted. Bath Spa and Chippenham will not be served. Disruption is expected until 19:30 13/06.
Customer Advice
The signals outside of Bath Spa station have failed. This is severely affecting our ability to run trains in the Bath Spa area.

Train services between Bristol Temple Meads and London Paddington are diverting, running straight to Swindon. Services between Bristol Temple Meads and Westbury are subject to delay or alteration. There are currenrly very few services running through Bath Spa. Road transport has been requested but with no reasonable timescale on when this might be in place.

We are expecting some road transport to operate from Bath Spa station. However, the first of these is not expected until about 19:30. Customers at Chippenham are advised to travel to Swindon and change for diverted services to Bristol Temple Meads.

There still are summer Saturday trains from Pembroke Dock to London Paddington - today's at 10:02 and 15:02

https://www.railwaymagazine.co.uk/25448/from-the-archive-the-fishguard-boat-express/ is an interesting potted history of the Fishguard train but does not give an exact date it last ran.  From https://historseye.wordpress.com/2017/03/26/britains-last-boat-trains/:

From the Western Telegraph:
There were a number of Wales and West services into London Waterloo to support Eurostar when it ran from there from places such as Manchester and Maesteg - and I have vague memories that there might have been one from Milford Haven?  Otherwise it was a long time ago

Just to clarify, these are planned cancellations due to the Berks & Hants Line closure for engineering works.

A shame that some form of shuttle service couldn't have operated between Paignton and Exeter/Taunton or perhaps even Westbury.

Normal service resumes from next weekend.

Last Saturday and today GWR have cancelled all London-Paignton trains advising travellers to change trains where necessary.

Last Saturday and today GWR have cancelled all London-Paignton trains advising travellers to change trains where necessary. Today of the seven diagrams covering Paignton-Exmouth the are four two car 150s diagrams The others being 2 x 3 car turbos and a 3 car 158) on the busiest day of the week.

As I understand it, there I much more freedom to choose your child's school these days and so the travel distances have gone up, and walking and cycling may be practical for less.  I was, perhaps, unusual but not unique in travelling by train to school - Petts Wood to Sydenham Hill and then to Sevenoaks, totally beyond walking distance - but walking to and from the stations.  On rare occasions, I cycled to Sevenoaks but even in those days the roads were far from cycle friendly.   I have vague recollections of there being Mum's or Dad's taxis  used for some at both schools, but as I used other entrances, I have no idea of volume.

Just on Thursday afternoon, I saw the 555 bus arrive at the top of our street and drop off half a dozen school children from Corsham.  This is a double deck school service and I understand it is very fully loaded - to the extent that there is no encouragement to market it further though general public may use it if they wish.  Other buses and coaches pick up from Melksham Market Place and it's educational to see the volumes picked up there on a school day for various other towns on both early service buses and special school runs.


Dead right.  It needs to be safe and practical. Our local secondary school has recently had a "new" path opened from the new build estates to the school, at massive expense (many consider it over-engineered) and that save a long walk around 3 sides of a square, including o a shared cycle and walking path on the side of the A365 which is really far too narrow for the traffic it was taking.  Interesting, I write "new" - there has been a public footpath across the fields since before the school was located there, but it was rarely used by any school child; I can recall just one occasion when out walking the dog, mid-winter - seeing a boy using it, and stepping in and through the mud getting his shoes and trousers covered.   

Drop off time may be an issue; pick up time is worse with all the parents arriving early to be there and close to save the little darlings having to walk too far.  Car parking is inadequate for pickup, and unrestricted roads close to the school become linear car parks for a while.
