Is it possible to turn trains around at Aldgate on the Green Line's platforms?

[NJTFAN1235!]

So at Aldgate, on the Green Line tracks, there's three tracks, one used for trains heading to Oxford Cross, another to turn trains that go to Beckton Jct and another track coming from the city center towards Simpleton.

If I wanted to make a shuttle service from Oxford Cross like say for example, The track on the Oxford Cross side is closed and no service operates further and terminate it at Aldgate, say for example, use the Simpleton track, how can trains get back to Oxford Cross?
