Rainhill and Rainford are fairly descriptive.
When I first passed through Rainham (Kent), on the second Network Day in 1986, it pretty well summed up the weather of that day. Though I believe the climate in this area is generally relatively dry.
To paraphrase Robert Louis Stephenson, to arrive at Hope station can be a disappointment.
Oh I don't know. On a nice day it's a pretty nice area. (Disclaimer: all my visits were in the late 90s, arriving at Hope having done the classic walk from Edale on the southern ridge)
Canterbury West is north of the city centre, Canterbury East is south of it
I found the geography of central Canterbury a bit confusing when I first visited in 1986 (same trip as Rainham, see above), arriving at West and departing from East. For some reason I imagined West to be on the south side and East to be on the north side, but that's maybe because I arrived from the Ashford direction (i.e. south of Canterbury) and departed in the Faversham direction (i.e. north of Canterbury).
Dean (Wilts) is in a valley (which is the meaning of 'dean' in most cases), but more normally, a 'dean' is a steep-sided valley in chalk country. Dean (Wilts) instead has a steep ridge (Dean Hill) to the south, but perhaps three or four miles of gradually rising land to the north before dropping away similarly steeply north of that - so not really a classic 'dean'.
