Where is this GE station?

Attached are two stills from the 1948 version of The Winslow Boy showing the arrival of a Holden F6 (7228) with a quin-art set (10A). At the time of filming, 7228 was allocated to Stratford. Does anyone recognise the station which was presumably on the GER section somewhere close to London (the film was made at Denham Studios, so they wouldn't want to go far to film the scene!)

Whoever knows can helpfully update this database.

Just a guess because I never really knew the GE suburban route out of Liverpool Street all that well especially the route from Bethnal Green to Cheshunt but maybe it is on the double-track section of the route starting just beyond Hackney Downs station that goes through Stoke Newington, Seven Sisters, Tottenham, Silver Street, Bruce Grove, Southbury and on towards Cheshunt?.

I'm don't think it's an Enfield line station; most were either on embankments or in cuttings.
My first impulse is Cheshunt, looking south from the up platform. The line is level and the station buildings appear to be on the downside. Also, the footbridge is about the right place (though I haven't seen any early pictures of Cheshunt to compare)
