I have been to Polesworth railway station before, though on that occaision i drove to it and was only able to look through the locked gates. Polesworth is what is known as a "difficult" station. It has one train a day, and that arrives at the station before 7am! In order to arrive at Polesworth by train i had to travel from Birmingham New Street before 6am and then get the one train a day to Polesworth from Nuneaton.
It was worth it though, and i was the station's only user that day as no one else boarded or alighted! Afterwards i had a look around the village and then took a bus back to Nuneaton. You can see my photos here.
