I see the top set of images on that page are of Abbey Wood station, and the photos look very nice, focusing on the wooden ceiling inside the station.
What the photos don't tell you is that many locals are (rightly IMO) up in arms: Partly because the lifts to the station entrance keep constantly breaking down. And partly because the original submitted plans for the station showed a large number of trees being planted on either side of the station. And the station is long-since completed, as is the area South of the station where many of the trees were going. But the trees are nowhere to be seen: instead there are two large expanses of concrete, which look a lot less pleasant. Not only that but, just outside the area captured by the main Crossrail photo of the station are two newly built and completely inadequate bus shelters, both perched high on a the flyover, so very exposed to the elements, but offering very little protection - and both looking rather less generous than the impression given in the initial photos of what was to be built (though possibly Crossrail aren't to blame for that one - not sure if that was down to Council decisions).
Then there's an issue of full platform length canopies that actually offer very little protection from rain etc., and a complete lack of anywhere warm to wait for trains when the weather is cold.
Possibly the pictures give a better impression than is actually the case if you need to use the station.
