Longest Time a Loco or Unit has been Stored & then Reinstated

[The Prisoner]

Frequently pass Crewe and see a selection of 90s and 92s stored, some of which have clearly been there for an age and look as if they will never work again.

Also aware of various 60s & 67s which are stored, some long term, and there are other units and locos of all types stored all over the country.

Question is do any of these long term stored locos and units ever come back into use after years, maybe decades out of use?

What is the longest a loco or unit has been stored for and then come back from the dead and been put back into use? Will qualify that this back into use on the network for some form of day to day service - not being repaired for a heritage line, and also going to dismiss complete reclassification (47 > 57, 56 > 69 etc).

92020 had been out of action for 17 years, stored in 2001 and returned to use in 2018. I think this has to be a contender?

41001 (43001)?

 

[61653 HTAFC]

141001 deserves a mention, spent its entire pre-refurbishment life as a Neville Hill 'Christmas Tree' until finally entering service as a face-lifted 141/1.
333009 similarly spent longer awaiting parts and having various bits "borrowed" than it had in service, until the mid-life refurbishment a few years ago.
