Yeah, I was thinking more shoppers or people who had other business in Tamworth rather than commuters. I have family who used to live in Dordon (which is basically Polesworth if you dont know the area, we certainly used to walk between the two places as kids) and they seemed to consider the whole area a suburb of Tamworth, I guess my opinion is influenced by that. People might get the train in and come back by car or something. It's not something you can build a routine around, obviously but it's just the only real use case I can think of for Polesworth station with it's current level of service.
It's probably worth saying that while the situation at Polesworth isnt idea I think on the whole the current LM timetable has been a big plus for North Warwickshire, with Tamworth (Staffs I know, but whatever) Atherstone, Nuneaton & Rugby having a fairly good rail connection amongst themselves for the first time in donkeys years.
