Seven of the class have been preserved but only six engines have run in preservation (46428 is undergoing restoration from scrapyard condition to working order at the East Lancs Railway).
Three members of the class have also operated on the mainline in preservation: No's 46441, 46443 & 46521.

46443 Became a popular mainline engine in the 1980s when it was one of the engines used during the 150th anniversary of the Great Western Railway traveling along many old branchlines including the old Bristol Harbour Railway.

46521 Saw use on the mainline in the 1990s but only saw a limited amount of use hauling excursion trains with one of its runs being on the GWML in December 1994.

46441 Was one of the smallest tender engines to operate on the former BR system during the 90's.
As well as being a regular at Carnforth and working at its home on the East Lancashire Railway it was also used for the regular steam on the met programme working trains alongside other steam engines.
46441 in recent years has been on static display inside the museum at the Ribble Steam Railway in Preston awaiting an overhaul.
In April 2018 the engine was moved by road to its new home at the Lakeside and Haverthwaite Railway, it is presently the only tender engine based at the railway.
The locos current owner Chris Beet who also owns LMS Jubilee no 45690 Leander is having the engine overhauled for use on the railway but it will not be returning to the mainline.

* Named in preservation
Only 46428 has yet to steam in preservation.
