Eh? Wolverhampton Station might not be smack bang in the middle of town like Walsall's, but it's not far at all! Google has it at 7 mins walk or 0.4 miles to the Mander Centre (if you consider that the main shopping area). Slightly less to Dudley Street, the main high street.
But if you're going somewhere to go shopping, you don't want a 10 minute trudge from the station, particularly if it's chucking down with rain. And that's on the way there - if you're laden with shopping a couple of hours later, you don't want to be dragging that 10 minutes up the road until you get to the station.
That, perhaps, is why the bus is more attractive - despite a slower journey it is more convenient.
Compare that '10 minute walk' with the situation at New Street or Moor Street where you're right by the shopping areas.
