With 22887 and 22890 not working, and obviously 24121 & 27809 still inactive you have to question why bother with the ALXs at all. 22581 appears to have been repaired as planned using 24116 as donor so that will be at Stockton soon

24116 is still in service at Stockton so it's not donated anything.  It could be 24121 or 24169 that have donated parts as they are both in a cannibalised state at Stockton.
