There are two types of branch line coaches on the North Western Railway. There were a number of orange four-wheeled coaches used on secondary and branch line services. As of the third season, Annie and Clarabel appear to be the only coaches of this kind left. However, two orange coaches appear in an eighth season learning segment. The red coaches are usually pulled by James, Duck and Oliver on their branch line in the television series, but are also used by the smaller engines on the Main Line.
