Was the one planned for a return to traffic?
I know 92020/032 were out fora long time a few years ago.
But 040 has been a long term demic for nearly 15-20 years now surely?!
The four GBRf-owned (ex-Europorte) 92s that are still stored are all at Brush now - 021, 040, 045 and 046. All were originally EPS (European Passenger Services) owned and all stored 24 April 2001 - so 19 years now.
There may have been on and off plans in the past, but no recent plans to reinstate any of these and they've all been used as spare donors to varying degrees (most of them a lot!) for the active 12 locos in the GB fleet. I'd be very surprised if any more came back - certainly as a traditional 92.
020 (also ex-EPS and stored at the same time) was reinstated in late 2018 after almost 18 years in store.
006 (ex-SNCF and stored in Feb 06) was reinstated in summer 2019 after 13 years in store.
032 was another ex-EPS one stored in April 2001 when Nightstar had died a death and EPS couldn't find buyers for their 7x 92s. It was returned to traffic in late 2009 after Europorte bought it (along with the other ex-EPS 92s) in 2007.
