Larimar is a new gem engine.
Larimar is a kind-hearted engine, who wishes to make others happy.
Larimar is based on an 0-4-0 saddle tank believed to have been built by the Avonside Engine Company of Bristol, but with components from Hunslet of Leeds and other builders. Percy and Matthew are also based on this engine, as was Padparadscha before her overhaul.
Larimar is painted cyan with blue lining. She has blue piston rods. Her light blue gem is on the sides of her coal bunker.
