Without doubt it's Victoria Station looking out towards the station approach.
My Dad was a porter-cum-lamp man there in the 1950's and 60's and I spent may hours of my childhood accompanying him to work where he regularly pushed me along the platforms on the back of a luggage trolley. He also allowed me to secure the lamps on the front and back of trains whilst they were parked at a platform, but I don't think @Elf n Safety' would be too happy with that. He also took on the station announcer's role advising travellers of incoming trains and the destination of outgoing trains. Once he'd done the announcing, and unknowingly to me, he used the microphone to contact Father Christmas's fairies to order a supply of goodies for me such as spangles, lucky bags, Fry's Five Boys chocolate bars and sherbet dips, but my wife thought I was stupid. (Only joking. I was only 6 or 7 at the time).
Happy days!
