There was an Occupation scheduled 4 weeks ago (see earlier in this thread) to install those points. Looks like something wasn't ready and they missed the window.
Yes, I was surprised to see the turnouts had not yet been constructed. Note: it COULD be a second turnout, I did look along the track and did not see a turnout stub coming from the east line. As stated the speed of the train makes detailed observations quite difficult.
I do not THINK the turnout rail kit was there, the original turnout kits used on the SG conversion came from Europe, Germany I believe (the pack has a metal label tied to it, giving its id and origin) and it appears to take ages to get these.
