I am currently looking at a railway platform from a moving train. The architecture of the platform, with its specific metal roof structure and orange safety barriers, is characteristic of older British railway stations. The style of the station infrastructure strongly suggests the United Kingdom. I am moderately sure this is a station in London.

then: forward

The view from the train shows a classic Victorian-style railway shed roof, which is very common in older London terminals. The specific lattice structure of the roof and the platform layout strongly resemble the architecture of London Paddington Station. The sun glare and the industrial aesthetic confirm a major urban UK rail hub. I am quite confident this is London, specifically Paddington.
