Work has started on the boiler overhaul of 44422. The components in the smokebox are being removed to facilitate the removal of the superheater elements and large flue tubes. The superheater header will also be removed and checked. The elements will also be checked to ascertain if they can be re-used.
The blast pipe has succumbed to age (well over 50 years old) and has become thin which has caused a hole to appear in the base. A new one will be cast.
The boiler will eventually be removed from the frames so that a full internal and external examination can take place.
