Carbon Limestone Co. No. 3 (Myrtle) is a 2-4-0 steam locomotive it was built in 1943 by H. K. Porter for Carbon Limestone Company and named Myrtle.

The locomotive was design to haul sugarcane for the Carbon Limestone Company until it was retired in 1945.

It was also originally used to move limestone from the carbon limestone quarry to a nearby crusher/distribution facility.

The LKPRR similarly altered the appearance of this engine, but gave it a slightly more modern appearance, representative of a typical oil-burning engine from the early 20th century.

Today it is restored by the Lahaina, Kaanapali and Pacific Railroad in Lahaina, Hawaii.
