Brief Encounter Locations

Photo 1 on your "Brief Encounter" section, is Willesden Junction.
The mainline platforms have since been removed, so it is no longer possible to take a "now" picture. The suburban side of the station still exists.
I got this information from this video: www.video125.co.uk
It doesn't mention Willesden in the text, but it does in the actuall video. There is also the comment that train drivers complained of being blinded by the intense arc lights, used to create the dramatic, back lit smoke effects in the title sequence.
