3979 has presumably finally been fitted with a new engine and sent back to Deptford as she is no longer at the back of Saltmeadows.
5267 is the next Coaster being prepared for repaint.
8228 is still having panels replaced.
5304 has also just recently arrived at Saltmeadows, presumably for general maintenance.
5229 is still at Saltmeadows in Northern, while sister 5230 is not visible. It is possible that she has already entered the paint shop to receive what is rumoured to be a striking pink livery.
