05:17 Gloucester to Southampton Central due 08:09
05:17 Gloucester to Southampton Central due 08:09 has been delayed at Swindon and is now 26 minutes late.
This is due to a problem currently under investigation.

Wonder if it's the train or the line ...

According to a Tweet to GWR from a passenger, the train had to reverse and run into another platform due to being too long.  My theory is that as it seems to be detaching a unit at Westbury this week as a means of getting units out of Gloucester due to the Filton Blockade, it was routed into Platform 2 Bay in error.   Due to run as 5E17 to Warminster to work 2E17  0723 Warminster to Bristol TM

Ah - which explains why that train from Warminster was also late for the same reason.

I'm surprised that in these days one sophisticated systems, there's nothing in the signalling that check train lengths into the Swindon bay ... it's not the first time ...

One of the few times I had any professional dealing with railways was investigating the use of a transponder system to detect and measure exactly where trains are. There are obviously ways to do that, but for a really reliable system the ideal is multiple senors based on different principles. What interest we got for the idea was to detect and count vehicles, both within the train and from fixed equipment. I was told then that the top of the wish list for better detection was train length - traditional signalling can't measure it directly. That came from someone doing metro systems, but I'm sure the same is true of heavy rail. Of course an axle counter does this too, but AFAIK the actual counts never get sent onwards to the signalling system.

12:20 Westbury to Swindon due 13:02 will be terminated at Chippenham.
It will no longer call at Swindon.
It is being delayed at Westbury.
This is due to a fault on this train.
