Mystic Quartz is a very friendly engine and is always quick to make friends.


Mystic Quartz was originally based on an 0-4-0 saddle tank believed to have been built by the Avonside Engine Company of Bristol with components from Hunslet of Leeds and other builders. She had a 2-4-2 wheel arrangement and a coal bunker based on that of 0-4-0 well tank No. 8069 "Tabamar", built in 1911 by Borsig, under contract from Decauville. "Tabamar" is preserved at the Chemin de fer des Chanteraines in Paris, France. In 1995, Tabamar visited the Ffestiniog Railway, where it served on drive-an-engine duty at Boston Lodge.

When she returned in Stories From Sodor:Future she was redesigned to be based on a Colombian Steam Motor engine built by Sentinel Waggon Works Ltd. All four of these engines have been scrapped. These engines were designed and built to run on metre gauge rails, whereas Mystic Quartz is standard gauge. Gator and Peacock Topaz are also based on one of these engines.


Originally, Mystic Quartz was painted lavender with rainbow colored lining and her rainbow colored gem on her coal bunker.

Since her redesign, she has been painted mauve with light blue lining and a light blue bufferbeam and footplate.


  • There are differences in the appearance of her gemstone between A Keystone Trip and Rainbow Colored Friends:
    • It changes in colour from a rainbow to pink, purple, and blue.
    • The shape of the facet changes from diamond to a pentagon
