I - managed - to leave Calne out of my "spoiler" list.   This has often struck me as a branch which - had it survived a further 20 years - would now be the terminus of a service from Bristol ... calling at stations along the way that remain, plus Saltford, Bathampton, Box, and Corsham.

 
Ah, Highworth. I visited the station site using the relatively frequent bus service, on a sunny day post Covid, when Highworth came across as stunned rather than sleeping. The wall in the photo alongside the alley from the road called 'Windrush' was a puzzle. On the site of the goods shed, it doesn't align with the structure, but looks to be built partly with bricks reclaimed from the platform face.

That aside, the railway, on a rural site, obliterated by the later housing, at the edge of which a length of trackbed untouched since the line closed immediately asserted itself.

On old maps, the line through Highworth station very much suggests intentions to head on, but it's not clear to where - though at some distance and across the young Thames, the Fairford branch beckoned. If it's ok I'll imagine a Bristol to Oxford train service via Witney - a rather unlikely relief for the capacity issues on the Didcot to Oxford line.
