The Narrow Gauge Breakdown Train is composed of one crane and conflat. It is often hauled by Rusty and used to mend the line and put engines back on the rails. The crane was also seen on the Mid Sodor Railway in the television series. Unlike the North Western Railway's breakdown train, the Narrow Gauge breakdown train does not have a works unit coach for the workmen. However, it is occasionally equipped with a brake van.
A secondary type of Breakdown Train mounted on an open-wagon truck and accompanied with a brown brake van.
The primary Narrow Gauge Breakdown Train is based on a French Magnard six ton crane used in World War I.
From the fourth series to the sixth series, the primary breakdown train was painted a reddish-brown all over. From the seventh series onwards, the crane itself became green while the conflats remained red.
