The Ballast Spreader is an unusual-looking machine who replaces ballast on the North Western Railway. Unusually, he/she appears to be wearing glasses in the illustration.
In the Wooden Railway range, the Ballast Spreader is known as the "Sodor Railway Repair". However, this title is technically inaccurate, as he/she belongs to the North Western Railway and is not strictly used for repair.
The Ballast Spreader is painted yellow and carries the words "SODOR CHAIN LOAD UNDERCUT" on his/her side.
The Ballast Spreader's specific basis is currently unknown, however it is based on a Ballast regulator, a piece of rail transport maintenance of way equipment used to shape and distribute the gravel track ballast. They are often used in conjunction with ballast tampers when maintaining track.
