It's a fair comment, but a bike rack cover and other unnecessary 'nonsenses' will be an insignificant proportion of the overall cost. The big ticket items (car park, pedestrian bridge, lifts, lighting, dealing with mine workings) are all done for a reason. The photo on the Wikipedia page suggests they've gone for a 'functional' rather than 'fancy' public realm - there's no gold/bronze cladding like Wakefield Westgate, tarmac platform surface rather than block paving etc.
But it all adds up. I seem to recall there was lots of palisade fencing around the site-why have this when people can get on the track from the platforms?
Lots of money spent on CCTV cameras but small waiting shelters, probably inadequate in the rain for the passengers- with seating comprising an uncomfortable narrow steel rail. As someone else has pointed out a direct exit from the westbound platform southward (not just to the cycleway) would have saved some passengers having to cross the footbridge and car park to reach the main road. Such an exit might have allowed the lift to be cut.
