The Magic Buffers are a set of old buffers located by Diesel 10's Mountain and the Sodor Wishing Well on the Kirk Ronan Branch Line.
The buffers send anyone through the Magic Railroad.
Thomas and Percy were discussing while delivering the mail how Mr. Conductor travels between Sodor to his hometown. They figured out that there must be a set of buffers that goes through a secret railway, which Diesel 10 overheard and told Splatter and Dodge that they must find the buffers and destroy Mr. Conductor once and for all.
They only appeared in Thomas and the Magic Railroad.
- In the original script, Diesel 10's original motivation was to just smash all the buffers so the steam engines can derail.
- The buffers are illustrated as crossing gates in the book.
