My clue on the first one is that you could actually see a DLR line in the background - therefore its either a station near an interchange, or an entrance a looong way from the platforms. It was the latter, from Google Earthing it.
I struggled with the second, until I noticed the double set of fluorescent lights, it turns out not many DLR (red handrails on the stairs, blue girders holding the platforms up) stationcould be s have these, once WIQ noted as a possible answer, the roof structure was also found to match.
I still have no idea where I've seen a similar picture before...
