[2] South Western Railway operate a limited service between London Waterloo and Yeovil Junction via Castle Cary.

From summer 2016 there was also a "seaside special" service between Weymouth and Salisbury or Waterloo via Yeovil Junction, but this was withdrawn in 2020 during the COVID-19 pandemic.

These were introduced in the late 2010s after they were released from the Thames Valley during the modernisation of the Great Western Main Line, although Class 158s are still occasionally used.

Past rolling stock has included locomotive-hauled trains, including British Railways Mark 2 coaches hauled by Class 67 used to strengthen high-demand summer Saturday services in 2008–2010 between Bristol and the seaside resort of Weymouth.

[1] A Bristol to Weymouth Rail Partnership was created in 1998 so that local authorities could support the line.
