Trees were accessories sold for the Thomas Wooden Railway primarily from 1993 to 2001. They originally came in packs of five, which included two maple trees and three pine trees. They were also sold in various sets. The maple trees had rectangular trunks from 1993 to 1999. From 1999 to 2012, they had rounded cone-shaped trunks. As of 2013, the maple trees are now one individual cut-out piece.
The trees come in many variations, including:
- Maple Tree
- Apple Tree
- Red-leaved Maple Tree
- Yellow-leaved Maple Tree
- Unpainted Maple Tree (Sold with Paint and Play Depot with Toby)
- Regular Pine Tree
- Snow-capped Pine Tree
- Gold Dust Covered Pine Trees (Sold with Gold Mine Mountain Set)
- Christmas Tree (Sold with Holiday Thomas and Countdown to Christmas Calendar)
- Since the pre-2013 maple trees have removable trunks, they can also be used as bushes.
