C7 No 2202 is heading south with a secondary express and a TPO behind the tender. My guess is that it's heading for Newcastle (or York?) and the wayside station would be on the ECML between Edinburgh and Newcastle (or York?). Can anybody identify the station, please?

Thanks to John Smart, the station has been identified as Longniddry, on the outskirts of Edinburgh. Other details about the working have also been resolved, helping make sure this picture will shine in "LNER trains etc." Vol.2 about the Secondary Services (now renamed by Ian Allan as: "Secondary, Branch Line and Non-Passenger Services").
Confirmation comes from Paul Tetlaw who has just travelled along the ECML, the curve and houses all fitting in, some three-quarters of a century later! (2-5-15)
