Read in the past few editions of both Steam Scene and Depot Diary, available on their website.
The tender of 5711 is apparently going to Chullora for major restoration at some point soon, I do not know any more.
1022 has had axle boxes and wheel bearings installed with the frame ready to be lowered.
1308 has apparently had major work done on the side tanks and other components.
I could be wrong with this information, I am not associated with them in any way
