73133 and 37602. 37602 arrived on 14th February 2019 for wheelset repairs, for worn tyres, but was stored in September, at which time it was on stands in the works. The bogies under 37602 at arrival were of cast type but it is now on a pair of fabricated bogies, and these are not particularly clean, where one could speculate that these are not for further revenue use.
87002 arrived on works on 22nd November, and was being shunted in this rubbed down condition. 86101 was much more advanced when photographed on 15th January.
47815 appears to have completed its repairs, and was removed from works on Friday 7th.
