Callan is a station on Sodor in the television series, located on the Misty Valley Branch Line. It was here where Oliver pulled S. C. Ruffey apart. Tom Tipper delivered mail here. Its name comes from the River Callan. The station building is just like the building at Arlesburgh West in the Railway Series.
There is also a yard located beside the station.
- Callan's design appears to be based on Arlesburgh West as it appeared during Gunvor and Peter Edwards's time as the illustrators of the Railway Series.
- As a result, Callan's design is based on Ravenglass railway station, which is also the basis of Arlesburgh West in the Railway Series.
