Yes. One set resides at the Downpatrick preservation line along with two class 80 sets. In fact that Class 450 was very recently used in an episode of Derry Girls. Number 458 "Antrim Castle" to be specific. She has been living on the preservation line since 2014.
A great shame to see them go. i hope a set have been saved and gone to a Heritage railway.
Rest assured one Class 450 set went to the Downpatrick line and has been preserved since 2014. Can still be seen to this day.
Are any being kept for preservation?
