This is a highly developed and precision engineered chuff pipe that can bring the real sound of a working steam loco.
It is machined from solid brass to a design that has been proven, through extensive testing and customer trials, to give an excellent chuff.
The chuff pipe consists of a jet within a narrow throat. This has a specially designed sounding slot, hand cut into the machined body. The body above the slot is machined out to give the maximum volume for resonance, which, when mounted within the chimney of the loco, amplifies the sound.
This model is suitable for the following Accucraft locomotive:
