London - King's Cross station, looking N in the W bay of the trainshed 2015-06-04

Built in 1851-2 for the Great Northern Railway to the designs of Lewis Cubitt. The arches supporting the roof were originally of laminated timber, but were replaced with wrought-iron plate in 1886-7. List description: list.historicengland.org.uk/resultsingle.aspx?uid=1078328 .

I think that a fault had resulted in this half of the station being virtually deserted - the train that I was about to catch usually leaves from one of these platforms, but departed from platform 0, on the east side of the station, to the confusion of people who were expecting to find a different train there.
