Above and below photographs of the boiler cradle show the steam pipe from the smokebox to the front ball joint being tacked together.
Above, the steam pipe is tacked together and removed from the job for welding, whilst below, a start is made on the steam pipe to the hind ball joint.
At each end of the boiler cradle, a steam ball joint, steam pipe expansion joint and exhaust ball joint provide the flexibility famous in the Garratt design.
