When Thomas arrived in Alice Springs, he heard a black Australian Engine blowing her horn loudly.
The Australian Engine is based on a SAR 400 Class 4-8-2+2-8-4 Garratt. Two members of this class are preserved.
She is painted black with a red bufferbeam.
- Thomas Crosses Australia (does not speak)
- Although she is a steam engine, she has a horn, which is the same as Mavis' current seventeenth season one; which is actually Diesel's from Misty Island Rescue to the fourteenth season.
- She is the first cape gauge engine to be introduced into the franchise.
