The difficulty with Norton Bridge is that no one really lives there! It isn't so much the station closing that is the surprise, but the fact it ever opened!!
Etruia was different, that was an area, but is slowly disappeared with redevelopment, etc, and suddenly Etruia isn't really a place anymore. I suspect most people would not know where Etruia is now if you asked them. The station clung on as the last remaining relic of the name, but in the end had to go, as the area had simply gone.
Norton Bridge has never been a big place, and hasn't grown. Even if every Norton Bridge resident caught the train, it still wouldn't produce many passengers.
Wedgwood and Barlaston are different. Barlaston is a sizeable village, and the station is close to the village centre. I think it is the sensible one to have trains calling. Wedgwood, doesn't really have many houses close enough. It would serve the factory and visitor attraction, but unless trains come and go to serve factory shift times, it is of little use to workers. It is also located on private roads (belonging to Wedgwood) so access can be tricky, and there is a weight limit on a bridge, and height restriction too. Barlaston the better bet to reopen
