The Ballast Spreader is an unusual-looking machine who replaces ballast on the North Western Railway. Unusually, he/she is seen wearing glasses.
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 unknown, however he/she 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.
