What have they in common?
Westbury Station seems like a strong theme to me

I'll let others answer the remaining question

Indeed ... and your avatar seems to have a similar theme

It's simply a whole lot of pictures I've taken since 21st June - start of summer ... with a little bit less stress on trains and a bit more on places you can go and things you can do by train.
I'll be going back a few weeks in my pictures at some stage and add more variety in ... it's very strong on TransWilts and Heart of Wessex at the moment.
