Bumpers are small track pieces. Bumpers connect to track and end the respective line. Bumpers were sold in the 2 Bumpers & 2 Signs pack with a stop sign and a railroad crossing sign and have also been featured in several sets as well as exclusive Toys R Us track packs. Currently, bumpers can be ordered individually from the Official Website.
- Within the Thomas and Friends series, bumpers are referred to as "buffers."
