This drama has a scene filmed onboard what appears to be a Class 455 EMU, the views outside the window show the area around Southwark and Bermondsey. There is also a scene filmed at London Paddington station.

The view out of the train window shows The Gherkin in the centre distance. Does anybody know precisely where this view is?
