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. They were usually pulled by Edward, Henry and James. Annie and Clarabel seem to be the only orange coaches left.
In the television series, the red coaches are usually pulled by Duck and Oliver on their branch line or by Edward on his branch line, but are also used by Henry and James on the Main Line. They were also pulled by Stepney on his branch line. Thomas pulls these when Annie and Clarabel are being repaired.
The branch line coaches are based on LBSCR Stroudley four-wheel coaches. Annie and Clarabel are also members of this basis.
- In the annual story, Pantomime Pranks, one of the orange branch line coaches was painted green. In the magazine story, Rain or Shine, one of the orange branch line coaches was painted yellow.
- In Hero of the Rails and The Lion of Sodor, one of the red branch line coaches is painted brown. Coaches painted blue, green, yellow, orange, black, and white were featured in a game on the Official Website.
- The orange branch line coaches resemble Annie and Clarabel.
- The orange branch line guard compartments did not have the duckets that feature on the red or LB&SC Railway examples. Instead a piece of card or plastic covers over this area.
- The duckets on the red branch line coaches are beaded. This makes them similar to the Stroudley coaches that received modification from 1911 onwards, as they were originally flush and fashioned from three sections of iron sheet.
- The red branch coaches also differ from the Stroudley coaches with their oil lamp pots, as they have a round base instead of the square base ones that were used on the LB&SC Railway.
