From the aerial photos I have seen I would have guessed that it had been heading away from Sandilands, but I may be being misled by the angle at which it is lying. Of course, we can't assume that it had actually stopped at Sandilands if it had come from that direction and could have been travelling at quite a high speed if it had not stopped there.
The direction is still not clear but the number of passengers involved in the morning peak would suggest inbound from New Addington towards Croydon. Downhill from the tunnel and failing to negotiate the left-hand curve towards Sandilands.
However, it does seem this most basic piece of information is not yet confirmed.
