The view above shows the same cylinder with the refurbished steel cladding fitted. The primary function of this is to retain the insulation but also provides a smooth surface for painting and allows for easier cleaning.

Above the cylinder can be seen the re-fitted steam heat pipe with white fibreglass lagging, steam for heating the carriages will eventually pass through this.

The circular bellows-like structure immediately on top of the cylinder is the right hand exhaust pipe. This will carry the spent steam from the cylinder to the blast pipe in the smokebox, where it will mix with hot gases from the firebox and exit through the chimney
