Given that the driver for the works is to provide step-free access I suspect that there will be at least one ticket machine. I can't imagine that TfL would add an entrance these days without oyster readers, but my guess is that they'll be the stand-alone type rather than a gateline (which would cost more and possibly require additional staffing).

I saw that, but I hope the entrance will be open most of the time (not like the daft arrangements at Epping). Also, I'm surprised that EFDC own the footway and ramps. I'd have though as a public footpath, it'd be the County Council.
This project is coming along and looks like a very good job in terms of workmanship.
There are stand alone Oyster readers - which are up and running (at least the one on the eastbound platform). The entrance isn't in use yet.
With no barrier, at the end of a relatively isolated alley, at the opposite end of the platform from the ticket hall, the entrances do seem vulnerable to antisocial behaviour. That might have been reduced with a barrier, at the entrance to the walkway, but there isn't space. I hope that they are kept open, but suspect they might eventually end up locked with some form of intercom to the booking hall if needed. Walking to Buckhurst Hill from my house, the entrance will shave off 5 minutes, because I can directly enter the Westbound platform from the subway.
If they installed ticket gates they would have to be staffed and I believe Buckhurst Hill only has one CSS on duty at a time. Also the gateline would have to be covered as I'm not sure rain etc. would be good for the electricals
