This turned up as a suggested video this morning. it is a mainly cab view of a service in 1980 from Epping to Ongar, back to Epping, then non-stop to Loughton Platform 1. On arrival at Loughton the camera is moved to the platform and the train moves off signalled by the shunt signal with an indicator reading 4. After a couple of minutes the train (I assume the same one) reappears heading eastbound in the siding adjacent to Platform 1. The quality isn't great as I suspect at that age it was transferred from VHS.
At school they taught me how to be, so pure in thought and word and deed, they didn't quite succeed Pet Shop Boys - It's a sin (1987) ___________________________________________________________________________ District Dave's London Underground Site Webmaster
